Abstract
Dental implant (1) and piece (11) to be connected to a dental implant (1), characterised in that both (1, 11) are capable of being connected to each other by an internal connection to the dental implant (1). The internal connection principally comprises an anti-rotational part (6, 16) and a cylindrical part (8, 18), with the anti-rotational part being formed by the repetition of a series of anti-rotational components (20, 20'), each of them formed by a series of arcs (21, 22, 23, 24, 25, 21 ', 22', 23', 24', 25') tangent to each other. This design of the anti-rotational part enables better performance to be obtained than with known anti-rotational designs.
Description
DENTAL IMPLANT PIECES TO BE CONNECTED TO A DENTAL
IMPLANT, AND THE INTERNAL CONNECTION BETWEEN THE
DENTAL IMPLANT AND EACH PIECE
DESCRIPTION
Technical field The present invention relates to the connection between a dental implant and a prosthetic/prosthodontic element or, in general, any part or piece to be connected to a dental implant, where said connection is of the type known as an "internal connection", as it is made inside the implant.
Prior art A dental implant is basically a surgical piece with certain biological properties that is inserted into the maxillary bone of a patient and to which is connected a prosthetic element, wherein said prosthetic element is a piece that supports one or more artificial dental pieces. The insertion procedure of the implant is coinplex, although this can be summarised by an initial creation of an alveolus in the patient's maxillary, a subsequent insertion of the implant, the optional wait involving a specific tiine for the osseointegration of the implant in the maxillary bone to occur, and the final fitting of the prosthetic element by means of its connection to the dental implant and the subsequent connection of a screw that connects the prosthetic element with the dental implant.
In relation to this last step, the prior art contains inultiple types of designs of connections between implants and prosthetic elements, wherein a "connection" is understood as the design of the parts of the iunplant and the prosthetic eleinent that must be asseinbled and connected to each other.
Generally speaking, the connection between an implant and a prosthetic eleinent lnust meet diverse requirements, the principal one being that said connection presents a substantially indefinite duration, i.e. that the robustness of the connection is not reduced during the use of the prosthetic eleinent or tooth throughout the life of the patient. This requirement is translated into other more specific ones such as that the distribution of forces or loads to which the prosthetic element is subjected has to be as uniform as possible all the way along the iinplant so that it does not arise that one part of the implant is especially overloaded leading to the possible deterioration of the connection between the implant and the maxillary bone, due to alterations in the homeostasis or to a physiological replacement of the peri-implant bone tissue or the bone tissue that surrounds the iinplant (a normal biological process during the life of the patient). Maintenance of an osseointegrated implant during an entire lifetiine is conditioned by mechanical factors dependent upon the stresses and load that the iinplant experiences and which it may transmit to the bone tissue impacting on the calcification or stability of said tissue.
An implant must also be capable of being connected to another type of piece such as the transporter (a piece that is used to transport or transfer the dental implant to the mouth of the patient and to insert and thread the dental iinplant in the patient's maxillary bone) or other types of prosthodontic eleirients. These connections must meet their own requireinents. An example of these requirements, as far as the connection between the implant and the transporter is concerned, concerns the capability of transmitting the maximuin rotation torque between transporter and implant (it should be boxne in mind that the transporter allows the implant to be threaded into the patient's bone, as a consequence of which there must be as high a transmission of rotation torque in the connection between transporter and implant in order to facilitate the threading of the implant without causing the plastic deformation of the implant).
There are two different types of connection between a dental implant and a prosthetic/prosthodontic element or, in general, any piece to be connected to an iinplant: external connections and internal connections.
External connections are those in which the assembly zone between the iinplant and the piece is situated outside the implant, i.e. the iinplant presents a male character and the piece a female character. In contrast, in internal connections, the connection zone is situated inside the implant, as a consequence of which the implant can be considered the feinale piece and the piece to be connected to the iinplant can be considered the male piece.
IMPLANT, AND THE INTERNAL CONNECTION BETWEEN THE
DENTAL IMPLANT AND EACH PIECE
DESCRIPTION
Technical field The present invention relates to the connection between a dental implant and a prosthetic/prosthodontic element or, in general, any part or piece to be connected to a dental implant, where said connection is of the type known as an "internal connection", as it is made inside the implant.
Prior art A dental implant is basically a surgical piece with certain biological properties that is inserted into the maxillary bone of a patient and to which is connected a prosthetic element, wherein said prosthetic element is a piece that supports one or more artificial dental pieces. The insertion procedure of the implant is coinplex, although this can be summarised by an initial creation of an alveolus in the patient's maxillary, a subsequent insertion of the implant, the optional wait involving a specific tiine for the osseointegration of the implant in the maxillary bone to occur, and the final fitting of the prosthetic element by means of its connection to the dental implant and the subsequent connection of a screw that connects the prosthetic element with the dental implant.
In relation to this last step, the prior art contains inultiple types of designs of connections between implants and prosthetic elements, wherein a "connection" is understood as the design of the parts of the iunplant and the prosthetic eleinent that must be asseinbled and connected to each other.
Generally speaking, the connection between an implant and a prosthetic eleinent lnust meet diverse requirements, the principal one being that said connection presents a substantially indefinite duration, i.e. that the robustness of the connection is not reduced during the use of the prosthetic eleinent or tooth throughout the life of the patient. This requirement is translated into other more specific ones such as that the distribution of forces or loads to which the prosthetic element is subjected has to be as uniform as possible all the way along the iinplant so that it does not arise that one part of the implant is especially overloaded leading to the possible deterioration of the connection between the implant and the maxillary bone, due to alterations in the homeostasis or to a physiological replacement of the peri-implant bone tissue or the bone tissue that surrounds the iinplant (a normal biological process during the life of the patient). Maintenance of an osseointegrated implant during an entire lifetiine is conditioned by mechanical factors dependent upon the stresses and load that the iinplant experiences and which it may transmit to the bone tissue impacting on the calcification or stability of said tissue.
An implant must also be capable of being connected to another type of piece such as the transporter (a piece that is used to transport or transfer the dental implant to the mouth of the patient and to insert and thread the dental iinplant in the patient's maxillary bone) or other types of prosthodontic eleirients. These connections must meet their own requireinents. An example of these requirements, as far as the connection between the implant and the transporter is concerned, concerns the capability of transmitting the maximuin rotation torque between transporter and implant (it should be boxne in mind that the transporter allows the implant to be threaded into the patient's bone, as a consequence of which there must be as high a transmission of rotation torque in the connection between transporter and implant in order to facilitate the threading of the implant without causing the plastic deformation of the implant).
There are two different types of connection between a dental implant and a prosthetic/prosthodontic element or, in general, any piece to be connected to an iinplant: external connections and internal connections.
External connections are those in which the assembly zone between the iinplant and the piece is situated outside the implant, i.e. the iinplant presents a male character and the piece a female character. In contrast, in internal connections, the connection zone is situated inside the implant, as a consequence of which the implant can be considered the feinale piece and the piece to be connected to the iinplant can be considered the male piece.
It has been demonstrated how the internal connections present certain advantages in relation to the external connections, such as, in the case of a connection between implant and prosthetic element, ininimising the possibilities of a loosening between the prosthetic element and the implant, and enabling an improved distribution of stresses and a greater stability of the implant/prosthetic element unit in the event of overloading. Furthermore, as an implant with an internal connection can present a head with a smaller height than an iinplant with an external connection, the former is more suitable for applications in which the implant is inserted in the maxillary bone of the patient in a submersed way, in which, during osseointegration, the iinplant is hidden beneath the gum. Additionally, an internal connection facilitates the insertion of the prosthetic element, as it is easier to position and fit a male element in a female element than to conduct the opposite process.
The prior art contains inultitude types of designs of internal connections between dental implants and prosthetic/prosthodontic elements or, in general, any piece to be connected to a dental implant. The present invention is an alternative to said designs.
Brief description of the invention It is an object of this invention to provide a dental implant and a prosthetic/prosthodontic element or, in general, any piece to be connected to a dental implant, wherein the implant and the piece are capable of being connected to each other by an internal connection, i.e. by a connection in which the piece behaves as a male element and the dental implant behaves as a female element. The inventive internal connection guarantees great strength and at the saine time does not compromise the manufacturability or the cost of the dental iinplant and the piece to be connected to the dental iinplant.
The internal connection between the iinplant and the piece principally comprises an anti-rotational part and a cylindrical part. The anti-rotational part inust coinplete a series of functions and requirements. Firstly, its main function is to prevent the piece from rotating in relation to the dental implant.

The inventive internal connection guarantees great strength and at the saine time does not compromise the manufacturability or the cost of the dental iinplant and the piece to be connected to the dental iinplant.
The internal connection between the iinplant and the piece principally comprises an anti-rotational part and a cylindrical part. The anti-rotational part inust coinplete a series of functions and requirements. Firstly, its main function is to prevent the piece from rotating in relation to the dental implant.
Furthermore, in the event that the piece is a prosthetic eleinent, the anti-rotational part must guarantee the resistance of the iinplant during the insertion phase of the prosthetic eleinent and facilitate the positioning and insertion of the prosthetic element, creating a guide to facilitate the asseinbly of the prosthetic element on the dental implant. Additionally, in the event that the piece is a transporter, the anti-rotational part inust have the capacity to transinit the necessary torque to insert the iinplant without causing permanent deformation on the implant.
In the inventive internal connection, the anti-rotational part is formed in a geometry based on arcs that are tangent to each other. This geometry of the anti-rotational part meets the aforementioned requirements, as can be seen in the detailed description of the invention. Furthermore, because the anti-rotational part is based on tangent arcs and, therefore, uses only rounded forms, it prevents the accumulation of stresses at specific points of the anti-rotational part and, by extension, at specific points of the implant and the piece connected to the implant.
In addition, the geometry of tangent arcs is such that there are controlled clearances or gaps between the piece and the implant, and the point of contact between the anti-rotational zones of the piece and the implant is created as far away as possible from the centre of the geometry or the longitudinal axis of the implant and the part (where said axis constitutes the axis of rotation of the piece), thereby increasing the transmission of the rotation torque from the piece to the iunplant in relation to known designs of anti-rotational parts in which the contact occurs at points that are closer to the longitudinal axis of the implant and the piece.
With regard to the specific embodiment of the dental iunplant provided with the aforementioned connection, said dental implant comprises a blind hole coinprising, in addition to a threaded zone for the connection of a screw, an anti-rotational zone and a cylindrical zone to provide the aforeinentioned anti-rotational and cylindrical parts of the internal connection. Said blind hole presents a conical inlet that facilitates the insertion of the prosthetic element.
In addition, the dental implant preferably presents a neck in cylindrical form finished optionally in a conical threaded zone. The conical threaded zone iinproves the stability of the iinplant during the first phase of surgery (the insertion of the implant in the maxillary bone of the patient), as it increases the 5 friction between implant and bone as the iinplant is introduced into the bone.
The area of contact between the iinplant and the bone is increased in this area by means of a physical/chemical -treatment, such as preferably acid etching of said surface. Optionally it is coated with a preparation with osteoinductive and osteoconductive properties (such as the plasma rich in growth factors described in W00044314A1), by virtue of which the osseointegration of the iinplant is accelerated and improved.
The dimensions of the dental implant are calculated to offer optimal strength without resulting in an excessively large iinplant. Said dimensions are detailed in the description of the figures.
The piece to be connected to the inventive dental implant also presents an anti-rotational area and a cylindrical area to provide the aforeinentioned anti-rotational and cylindrical parts of the internal connection. Both the anti-rotational area and the cylindrical area present a bevelled end to facilitate the insertion of said piece in the blind hole of the dental implant.
Brief description of the drawings The details of the invention can be seen in the figures attached, which do not aim to restrict the scope of the invention:
- Figure 1 shows a partially cross-sectioned elevation of an embodiment of a dental implant according to the invention.
- Figure 2 shows a top view of the dental implant of Figure 1.

- Figure 4 shows a bottom view of the prosthetic eleinent of Figure 3.
- Figure 5 shows a partial view of an anti-rotational coinponent of the anti-rotational area of the iinplant of Figure 1.
In the inventive internal connection, the anti-rotational part is formed in a geometry based on arcs that are tangent to each other. This geometry of the anti-rotational part meets the aforementioned requirements, as can be seen in the detailed description of the invention. Furthermore, because the anti-rotational part is based on tangent arcs and, therefore, uses only rounded forms, it prevents the accumulation of stresses at specific points of the anti-rotational part and, by extension, at specific points of the implant and the piece connected to the implant.
In addition, the geometry of tangent arcs is such that there are controlled clearances or gaps between the piece and the implant, and the point of contact between the anti-rotational zones of the piece and the implant is created as far away as possible from the centre of the geometry or the longitudinal axis of the implant and the part (where said axis constitutes the axis of rotation of the piece), thereby increasing the transmission of the rotation torque from the piece to the iunplant in relation to known designs of anti-rotational parts in which the contact occurs at points that are closer to the longitudinal axis of the implant and the piece.
With regard to the specific embodiment of the dental iunplant provided with the aforementioned connection, said dental implant comprises a blind hole coinprising, in addition to a threaded zone for the connection of a screw, an anti-rotational zone and a cylindrical zone to provide the aforeinentioned anti-rotational and cylindrical parts of the internal connection. Said blind hole presents a conical inlet that facilitates the insertion of the prosthetic element.
In addition, the dental implant preferably presents a neck in cylindrical form finished optionally in a conical threaded zone. The conical threaded zone iinproves the stability of the iinplant during the first phase of surgery (the insertion of the implant in the maxillary bone of the patient), as it increases the 5 friction between implant and bone as the iinplant is introduced into the bone.
The area of contact between the iinplant and the bone is increased in this area by means of a physical/chemical -treatment, such as preferably acid etching of said surface. Optionally it is coated with a preparation with osteoinductive and osteoconductive properties (such as the plasma rich in growth factors described in W00044314A1), by virtue of which the osseointegration of the iinplant is accelerated and improved.
The dimensions of the dental implant are calculated to offer optimal strength without resulting in an excessively large iinplant. Said dimensions are detailed in the description of the figures.
The piece to be connected to the inventive dental implant also presents an anti-rotational area and a cylindrical area to provide the aforeinentioned anti-rotational and cylindrical parts of the internal connection. Both the anti-rotational area and the cylindrical area present a bevelled end to facilitate the insertion of said piece in the blind hole of the dental implant.

Detailed description of the invention Figure 1 shows a partially cross-sectioned elevation of the preferred embodiment of a dental implant (1) according to the invention. The dental implant (1), like all dental implants, is a piece that is fundamentally lengthened according to a longitudinal axis (5) and finished at the top part by a top surface (7). The main part of the dental implant (1) is a threaded body (27) to be fixed to the maxillary bone of the patient.
In the top part, the dental implant (1) comprises a cylindrical neck (2), with said neck (2) being finished in the area opposite the top surface (7) in a threaded conical area (19), so that the threaded body (27) begins with a conical part in the form of said threaded conical area (19). The neck (2) has a height (hl) of preferably between 0.5 and 2.5 min.
Furthermore, the dental implant (1) presents a blind hole (3) that constitutes the area of internal connection between the dental implant (1) and the prosthetic/prosthodontic element, i.e., the piece to be connected to the implant. Said blind hole (3) opens from the top surface (7) and comprises a conical inlet (4), an anti-rotational area (6), a cylindrical area (8) and a threaded area (9).
The conical inlet (4) facilitates the introduction of the piece in the blind hole (3) of the dental implant (1). Said conical inlet (3) presents an inclination in relation to the longitudinal axis (5) of preferably between 30 and 60 .
- Figure 7 shows a view of the superimposition or connection of the anti-rotational zones of the dental implant and the prosthetic element of the previous figures.
- Figures 8A and 8B show two perspectives of the dental implant of the previous figures.
- Figure 9 shows a perspective of the prosthetic element of the previous figures.
Detailed description of the invention Figure 1 shows a partially cross-sectioned elevation of the preferred embodiment of a dental implant (1) according to the invention. The dental implant (1), like all dental implants, is a piece that is fundamentally lengthened according to a longitudinal axis (5) and finished at the top part by a top surface (7). The main part of the dental implant (1) is a threaded body (27) to be fixed to the maxillary bone of the patient.
In the top part, the dental implant (1) comprises a cylindrical neck (2), with said neck (2) being finished in the area opposite the top surface (7) in a threaded conical area (19), so that the threaded body (27) begins with a conical part in the form of said threaded conical area (19). The neck (2) has a height (hl) of preferably between 0.5 and 2.5 min.
Furthermore, the dental implant (1) presents a blind hole (3) that constitutes the area of internal connection between the dental implant (1) and the prosthetic/prosthodontic element, i.e., the piece to be connected to the implant. Said blind hole (3) opens from the top surface (7) and comprises a conical inlet (4), an anti-rotational area (6), a cylindrical area (8) and a threaded area (9).
The conical inlet (4) facilitates the introduction of the piece in the blind hole (3) of the dental implant (1). Said conical inlet (3) presents an inclination in relation to the longitudinal axis (5) of preferably between 30 and 60 .
The cylindrical area (8) reinforces the dental implant (1) distributing the lateral loads and guiding the entrance of the piece. The depth (h3) of this cylindrical area (8) must be the maximuin that guarantees sufficient material on the wall of the dental implant (1) in order to support the loads to which the dental implant (1) is subjected. For this purpose, tlie cylindrical area (8) has a depth (h3), measured from the top surface (7) of preferably between 1.3 and 3 mm.
The threaded area (9) provides the area of connection of the screw that links the dental implant (1) to the piece. The diameter of this threaded area (9) must be reduced to guarantee an elevated wall thickness of the dental implant (1) and an elevated strength of the dental implant (1), and at the saine tiine it must be elevated to favour the integrity of the screw in the face of the forces that said screw must withstand. To achieve this, as a compromise solution by means of which these two opposing criteria are met adequately, the invention conteinplates threaded area (9) diameters of preferably between 1.1 and 2.5 mm.
The anti-rotational area (6) generally has a depth (h2), measured from the top surface (7) of preferably between 0.7 and 2 n:un. By means of these dimensions the anti-rotational area (6) is sufficiently deep for it to present a correct anti-rotational behaviour, but at the saine tiine not sufficiently deep for it to reach the threaded body (27) and have the thickness of the walls of the implant reduced problematically. At the same time, the threaded area (9) preferably has a depth (h4) measured from the top surface (7) of between 3.5 and 7.5 nun. These dimensions ensure a sufficient number of threads in the threaded area (9) to ensure that the connection between the implant and the screw that connects the dental iinplant and the piece is a suitable connection.
The top surface (7) of the dental iinplant (1) is totally flat in order to ensure a correct connection with the piece to be connected to the dental implant (1). The size of this top surface (7), delimited by the extent of the blind hole (3) and the diameter of the neck (2) of the dental implant (1), must be sufficiently large to ensure that the connection between the dental implant (1) and the piece can be capable of withstanding the vertical loads without being permanently defonned.
Figure 2 shows a top view of the dental iinplant (1), wherein the top surface (7), the conical inlet (4), the anti-rotational area (6) and the cylindrical area (8) can be seen. The anti-rotational area (6) presents in this preferred embodiment a total of four lobules (28). The specific fonn of the anti-rotational area (6) is detailed in subsequent figures. It can be seen, however, in the figure that the cylindrical area (8) is inscribed in the anti-rotational area (6), with the diameter of the cylindrical area (8) being substantially the same as the smallest diameter (D) of the anti-rotational area (6).
Figure 3 shows a cross-section elevation of an embodiment of a piece (11) to be connected to the inventive dental implant (1), with said piece (11) in this case being a prosthetic element (11). The prosthetic element (11), like the majority of prosthetic elements, is a fundamentally lengthened piece according to a longitudinal shaft (15) and provided with a central through hole (13) in order to insert the screw that connects the prosthetic element (11) to the dental implant (1). Said central through hole (13) includes a support area (14) on which the head of the aforementioned screw rests.
The prosthetic element (11) is provided with a contact surface (17) designed to be supported on the top surface (7) of the dental implant (1).
Said contact surface (17) must be perfectly flat to ensure correct closure with the dental implant (1).
From said contact surface (17) projects an anti-rotational area (16), which in turn ends in a bevelled area (10). Said bevelled area (10) softens the contact that occurs between the prosthetic element (11) and the dental implant (1) until the anti-rotational areas (16, 6) of both are correctly oriented during asseinbly.
Following the bevelled area (10), the prosthetic eleinent (11) includes a cylindrical area (18) that projects from said bevelled area (10) and which ends in a second bevelled area (12). This second bevelled area (12) facilitates the entry of the cylindrical area (18) in the conical inlet (4) of the dental iinplant (1).
The cylindrical area (18) facilitates the entry of the prosthetic eleinent (11) in the blind hole (3) of the dental implant (1). Thus, in a first phase of introduction it is easy to enter the cylindrical area (18) in the anti-rotational area (6) of the dental iunplant (1). Additionally, the cylindrical zone (18) absorbs a certain part of the load suffered by the unit formed by the dental implant (1) and the prosthetic element (11) already installed in the mouth of the patient, thereby preventing the load from falling on the anti-rotational area (6) and achieving a more uniform distribution of the stresses on the dental implant (1).
The bevelled area (10) presents an inclination in relation to the longitudinal axis (15) of preferably between 30 and 60 . The anti-rotational area (16) has a depth (h12), measured from the contact surface (17), of preferably between 0.2 and 2 inm. These depths of the anti-rotational area (16) guarantee the operating capacity of said anti-rotational area (16) in the face of lateral loads.
Figure 4 shows a bottom view of the inventive prosthetic eleinent (11).
The anti-rotational area (16) presents in this embodiinent a total of four lobules (28'). The specific form of the anti-rotational area (16) is detailed in the figures below.
Both the anti-rotational area (6) of the dental iinplant (1) and the anti-rotational area (16) of the prosthetic element (11) are made with a preferably symmetrical outline, i.e., one that presents a certain periodicity or repetition. In the case of the dental implant (1) and the prosthetic element (11) of the figures, the anti-rotational areas (6, 16) consist of the repetition of an anti-rotational component (20, 20') a total of four times, rotated 90 each tiine until the circumference is coinpleted. Other inventive einbodiments with a larger, or smaller number of repetitions of the anti-rotational component (20, 20') are contemplated, giving rise to a larger or smaller nuinber of lobules (28, 28').
Figure 5 shows the anti-rotational component (20) of the anti-rotational area (6) of the dental iinplant (1). The anti-rotational component (20) comprises in this case a total of five arcs (21, 22, 23, 24, 25), tangent to each other and determined by respective radii (Rl, R2, R3), where the closest 5 point (26) of the anti-rotational component (20) to the longitudinal axis (5) determines the smallest diaineter (d) of the anti-rotational coinponent (20) and the anti-rotational area (6). As has been stated, the cylindrical area (8) is inscribed in the anti-rotational area (6) and its diaineter preferably coincides with this smallest diameter (d).
In the embodiment of the figure, the centre of the end arcs (21, 25) of the anti-rotational coinponent (20) is situated on the longitudinal axis (5).
In addition, the ratio between the radius (R2) of the arcs (22, 24) and the radius (Rl) of the end arcs (21, 25) is between 1:2 and 1:3, and the ratio between the radius (R3) of the central arc (23) and the radius (Rl) of the end arcs (21, 25) is between 3:1 and 4:1.
Figure 6 shows the anti-rotational component (20') of the anti-rotational area (16) of the prosthetic element (11). The anti-rotational component (20') comprises in this case a total of five arcs (21', 22', 23', 24', 25'), tangent to each other and detennined by respective radii (Rl', R2', R3'), where the closest point (26') of the anti-rotational component (20') to the longitudinal axis (15) determines the smallest diameter (d') of the anti-rotational component (20') and the anti-rotational area (16). The cylindrical area (18) is inscribed in the anti-rotational area (16) and its diameter preferably coincides with this smallest diameter (d').
In the embodiment of the figure, the centre of the end arcs (21', 25') of the anti-rotational component (20') is situated on the longitudinal axis (15).
In addition, the ratio between the radius (R2') of the arcs (22', 24') and the radius (Rl') of the end arcs (21', 25') is between 1:2 and 1:3, and the ratio between the radius (R3') of the central arc (23') and the radius (Rl') of the end arcs (21', 25') is between 1:1 and 1.5:1.
Different embodiinents of the anti-rotational coinponents (20, 20') are conteinplated with a number of arcs (21, 22, 23, 24, 25, 21', 22', 23', 24', 25') other then five, giving rise to a variable total number of lobules (28, 28').
Figure 7 shows the anti-rotational part that results from the connection between the anti-rotational area (6) of the dental iinplant (1) and the anti-rotational area (16) of the piece (11). As can be seen, the different ratio between the radii (R3, R1) of the anti-rotational area (6) and between the radii (R3', Rl') of the anti-rotational area (16) enables the appearance of a series of clearances (29), so that the areas of contact (30) between the dental implant (1) and the piece (11) are substantially as distant as possible from the longitudinal axis (5) without the anti-rotational part being prevented from operating as such. In this way the transinission of torque between the piece (11) and the dental implant (1) is increased, being this an interesting effect when the piece (11) is a transporter (1).
The radii (R1, Rl') are preferably coinprised between 2.5 and 4 mm, dimensions that enable a compromise solution to be reached between the interest in having a high radius (Rl, R') to increase the distance from the area of contact (30) to the longitudinal axis (5) and thereby increase the transmission of torque, and the interest in having a reduced radius (Rl, Rl') so that the top surface (7) is large so that the connection between the iinplant (1) and the and the prosthetic element (11) can withstand forces or lateral loads.
Figures 8A and 8B show two perspectives of the inventive dental implant (1) detailed in previous figures. Figure 8A shows a high number of eleinents detailed in previous figures, with the elements contained in the blind hole (3) that originates from the top surface (7) being particularly appreciable. Thus, it can be seen how said blind hole (3) begins in its uppermost part by the conical inlet (4), and continues with the anti-rotational area (6), the cylindrical area (8) and the threaded area (9). The anti-rotational area (6) consists of four equal anti-rotational coinponents (20), with each one of these anti-rotational components (20) being formed by five arcs (21, 22, 23, 24, 25) tangent to each other. The cylindrical area (8) is inscribed in the anti-rotational area (6). Figure 8B shows more clearly the exterior of the iinplant, and details the neck (2), the threaded body (27) inherent to the entire dental iinplant (1), and the conical threaded area (19) of the inventive iinplant.
Figure 9 shows a perspective of the inventive prosthetic element (11).
This figure shows how, from the contact surface (17), the elements that are to be housed in the blind hole (3) of the dental iinplant (1) originate: the anti-rotational area (16), finished in a bevel (10), and the cylindrical area (18), finished in a bevelled area (12). It can be seen how the anti-rotational area (16) coinprises various anti-rotational components (20'), and that each anti-rotational component (20') is coinposed of five arcs (21', 22', 23', 24', 25') tangent to each other.
It should be pointed out that the concave part corresponding to the central arc (23') of the anti-rotational component (16) is extended along the entire depth of the cylindrical area (18). This facilitates the fabrication of the piece.
By analysing Figures 8A, 8B and 9, an additional advantage of the inventive internal connection can be seen, nainely that the cylindrical areas (8, 18) are inscribed in the anti-rotational areas (6, 16), thereby achieving that during the insertion of the prosthetic element (11) into the dental implant (1) a guide is created from the moment at which the cylindrical area (8) of the prosthetic element (11) is introduced into the anti-rotational area (18) of the dental implant (1).
Furthermore, with regard to the piece (11) of Figure 9, it should be pointed out that the embodiment of pieces (11) not provided with the anti-rotational area (16), but which are compatible with a dental implant (1) that is provided with an anti-rotational area (6), is also contemplated. An example of this type of piece (11) is the transepithelial (a piece that enables the connection of inultiple prostheses to one or two dental iinplants and which for this purpose acts as an adaptor between the dental implant and the prosthetic element bearing multiple dental pieces). These types of pieces (11) inust enable the insertion of a bridge bearing inultiple dental pieces in the mouth of the patient, respecting the relative position of an iinplant with respect to another and at the same tiine facilitating the insertion of the bridge. For this reason, this type of piece coinprises only a non-anti-rotational area (18) from the contact surface (17).
The inventive internal connection presents a behaviour that is such that it can be valid for dental implants (1) and pieces (11) of widely varying sizes.
Thus, its application is envisaged in dental iinplants (1) of a length of between 7 and 35 mm (and even others), threaded body (27) diameters of between 3.3 and 7 mm (and even others), and top surface (7) diaineters of between 3.5 and 6.5 mm (and even others). Furthermore, it is envisaged that for a single unit or family of dental implants (1) and pieces (11) made up of implants (1) and pieces (11) of different sizes, the internal connection presented by all of them (1, 11) can be of the same size so as to achieve compatibility between all the dental iinplants (1) and all the pieces (11).
The invention also contemplates the embodiment of the internal connection in any scale or dimension, on any design of dental iinplant, and even the application of the internal connection to other types of implants or pieces that are not exclusively dental.
The threaded area (9) provides the area of connection of the screw that links the dental implant (1) to the piece. The diameter of this threaded area (9) must be reduced to guarantee an elevated wall thickness of the dental implant (1) and an elevated strength of the dental implant (1), and at the saine tiine it must be elevated to favour the integrity of the screw in the face of the forces that said screw must withstand. To achieve this, as a compromise solution by means of which these two opposing criteria are met adequately, the invention conteinplates threaded area (9) diameters of preferably between 1.1 and 2.5 mm.
The anti-rotational area (6) generally has a depth (h2), measured from the top surface (7) of preferably between 0.7 and 2 n:un. By means of these dimensions the anti-rotational area (6) is sufficiently deep for it to present a correct anti-rotational behaviour, but at the saine tiine not sufficiently deep for it to reach the threaded body (27) and have the thickness of the walls of the implant reduced problematically. At the same time, the threaded area (9) preferably has a depth (h4) measured from the top surface (7) of between 3.5 and 7.5 nun. These dimensions ensure a sufficient number of threads in the threaded area (9) to ensure that the connection between the implant and the screw that connects the dental iinplant and the piece is a suitable connection.
The top surface (7) of the dental iinplant (1) is totally flat in order to ensure a correct connection with the piece to be connected to the dental implant (1). The size of this top surface (7), delimited by the extent of the blind hole (3) and the diameter of the neck (2) of the dental implant (1), must be sufficiently large to ensure that the connection between the dental implant (1) and the piece can be capable of withstanding the vertical loads without being permanently defonned.
Figure 2 shows a top view of the dental iinplant (1), wherein the top surface (7), the conical inlet (4), the anti-rotational area (6) and the cylindrical area (8) can be seen. The anti-rotational area (6) presents in this preferred embodiment a total of four lobules (28). The specific fonn of the anti-rotational area (6) is detailed in subsequent figures. It can be seen, however, in the figure that the cylindrical area (8) is inscribed in the anti-rotational area (6), with the diameter of the cylindrical area (8) being substantially the same as the smallest diameter (D) of the anti-rotational area (6).
Figure 3 shows a cross-section elevation of an embodiment of a piece (11) to be connected to the inventive dental implant (1), with said piece (11) in this case being a prosthetic element (11). The prosthetic element (11), like the majority of prosthetic elements, is a fundamentally lengthened piece according to a longitudinal shaft (15) and provided with a central through hole (13) in order to insert the screw that connects the prosthetic element (11) to the dental implant (1). Said central through hole (13) includes a support area (14) on which the head of the aforementioned screw rests.
The prosthetic element (11) is provided with a contact surface (17) designed to be supported on the top surface (7) of the dental implant (1).
Said contact surface (17) must be perfectly flat to ensure correct closure with the dental implant (1).
From said contact surface (17) projects an anti-rotational area (16), which in turn ends in a bevelled area (10). Said bevelled area (10) softens the contact that occurs between the prosthetic element (11) and the dental implant (1) until the anti-rotational areas (16, 6) of both are correctly oriented during asseinbly.
Following the bevelled area (10), the prosthetic eleinent (11) includes a cylindrical area (18) that projects from said bevelled area (10) and which ends in a second bevelled area (12). This second bevelled area (12) facilitates the entry of the cylindrical area (18) in the conical inlet (4) of the dental iinplant (1).
The cylindrical area (18) facilitates the entry of the prosthetic eleinent (11) in the blind hole (3) of the dental implant (1). Thus, in a first phase of introduction it is easy to enter the cylindrical area (18) in the anti-rotational area (6) of the dental iunplant (1). Additionally, the cylindrical zone (18) absorbs a certain part of the load suffered by the unit formed by the dental implant (1) and the prosthetic element (11) already installed in the mouth of the patient, thereby preventing the load from falling on the anti-rotational area (6) and achieving a more uniform distribution of the stresses on the dental implant (1).
The bevelled area (10) presents an inclination in relation to the longitudinal axis (15) of preferably between 30 and 60 . The anti-rotational area (16) has a depth (h12), measured from the contact surface (17), of preferably between 0.2 and 2 inm. These depths of the anti-rotational area (16) guarantee the operating capacity of said anti-rotational area (16) in the face of lateral loads.
Figure 4 shows a bottom view of the inventive prosthetic eleinent (11).
The anti-rotational area (16) presents in this embodiinent a total of four lobules (28'). The specific form of the anti-rotational area (16) is detailed in the figures below.
Both the anti-rotational area (6) of the dental iinplant (1) and the anti-rotational area (16) of the prosthetic element (11) are made with a preferably symmetrical outline, i.e., one that presents a certain periodicity or repetition. In the case of the dental implant (1) and the prosthetic element (11) of the figures, the anti-rotational areas (6, 16) consist of the repetition of an anti-rotational component (20, 20') a total of four times, rotated 90 each tiine until the circumference is coinpleted. Other inventive einbodiments with a larger, or smaller number of repetitions of the anti-rotational component (20, 20') are contemplated, giving rise to a larger or smaller nuinber of lobules (28, 28').
Figure 5 shows the anti-rotational component (20) of the anti-rotational area (6) of the dental iinplant (1). The anti-rotational component (20) comprises in this case a total of five arcs (21, 22, 23, 24, 25), tangent to each other and determined by respective radii (Rl, R2, R3), where the closest 5 point (26) of the anti-rotational component (20) to the longitudinal axis (5) determines the smallest diaineter (d) of the anti-rotational coinponent (20) and the anti-rotational area (6). As has been stated, the cylindrical area (8) is inscribed in the anti-rotational area (6) and its diaineter preferably coincides with this smallest diameter (d).
In the embodiment of the figure, the centre of the end arcs (21, 25) of the anti-rotational coinponent (20) is situated on the longitudinal axis (5).
In addition, the ratio between the radius (R2) of the arcs (22, 24) and the radius (Rl) of the end arcs (21, 25) is between 1:2 and 1:3, and the ratio between the radius (R3) of the central arc (23) and the radius (Rl) of the end arcs (21, 25) is between 3:1 and 4:1.
Figure 6 shows the anti-rotational component (20') of the anti-rotational area (16) of the prosthetic element (11). The anti-rotational component (20') comprises in this case a total of five arcs (21', 22', 23', 24', 25'), tangent to each other and detennined by respective radii (Rl', R2', R3'), where the closest point (26') of the anti-rotational component (20') to the longitudinal axis (15) determines the smallest diameter (d') of the anti-rotational component (20') and the anti-rotational area (16). The cylindrical area (18) is inscribed in the anti-rotational area (16) and its diameter preferably coincides with this smallest diameter (d').
In the embodiment of the figure, the centre of the end arcs (21', 25') of the anti-rotational component (20') is situated on the longitudinal axis (15).
In addition, the ratio between the radius (R2') of the arcs (22', 24') and the radius (Rl') of the end arcs (21', 25') is between 1:2 and 1:3, and the ratio between the radius (R3') of the central arc (23') and the radius (Rl') of the end arcs (21', 25') is between 1:1 and 1.5:1.
Different embodiinents of the anti-rotational coinponents (20, 20') are conteinplated with a number of arcs (21, 22, 23, 24, 25, 21', 22', 23', 24', 25') other then five, giving rise to a variable total number of lobules (28, 28').
Figure 7 shows the anti-rotational part that results from the connection between the anti-rotational area (6) of the dental iinplant (1) and the anti-rotational area (16) of the piece (11). As can be seen, the different ratio between the radii (R3, R1) of the anti-rotational area (6) and between the radii (R3', Rl') of the anti-rotational area (16) enables the appearance of a series of clearances (29), so that the areas of contact (30) between the dental implant (1) and the piece (11) are substantially as distant as possible from the longitudinal axis (5) without the anti-rotational part being prevented from operating as such. In this way the transinission of torque between the piece (11) and the dental implant (1) is increased, being this an interesting effect when the piece (11) is a transporter (1).
The radii (R1, Rl') are preferably coinprised between 2.5 and 4 mm, dimensions that enable a compromise solution to be reached between the interest in having a high radius (Rl, R') to increase the distance from the area of contact (30) to the longitudinal axis (5) and thereby increase the transmission of torque, and the interest in having a reduced radius (Rl, Rl') so that the top surface (7) is large so that the connection between the iinplant (1) and the and the prosthetic element (11) can withstand forces or lateral loads.
Figures 8A and 8B show two perspectives of the inventive dental implant (1) detailed in previous figures. Figure 8A shows a high number of eleinents detailed in previous figures, with the elements contained in the blind hole (3) that originates from the top surface (7) being particularly appreciable. Thus, it can be seen how said blind hole (3) begins in its uppermost part by the conical inlet (4), and continues with the anti-rotational area (6), the cylindrical area (8) and the threaded area (9). The anti-rotational area (6) consists of four equal anti-rotational coinponents (20), with each one of these anti-rotational components (20) being formed by five arcs (21, 22, 23, 24, 25) tangent to each other. The cylindrical area (8) is inscribed in the anti-rotational area (6). Figure 8B shows more clearly the exterior of the iinplant, and details the neck (2), the threaded body (27) inherent to the entire dental iinplant (1), and the conical threaded area (19) of the inventive iinplant.
Figure 9 shows a perspective of the inventive prosthetic element (11).
This figure shows how, from the contact surface (17), the elements that are to be housed in the blind hole (3) of the dental iinplant (1) originate: the anti-rotational area (16), finished in a bevel (10), and the cylindrical area (18), finished in a bevelled area (12). It can be seen how the anti-rotational area (16) coinprises various anti-rotational components (20'), and that each anti-rotational component (20') is coinposed of five arcs (21', 22', 23', 24', 25') tangent to each other.
It should be pointed out that the concave part corresponding to the central arc (23') of the anti-rotational component (16) is extended along the entire depth of the cylindrical area (18). This facilitates the fabrication of the piece.
