This is a reissue patent application from U.S. Pat. No. 5,741,500, issued on Apr. 21, 1998.
1. Field of the Invention
The instant invention relates generally to holding devices and more specifically it relates to a gum growth pad.
2. Description of the Prior Art
Numerous holding devices have been provided in prior art. For example, U.S. Pat. Nos. 3,510,053 to Focke; 5,197,882 to Jernberg; 5,267,862 to Parker and 5,326,685 to Gaglio et al. are all illustrative to such prior art. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.
U.S. Pat. No. 3,510,053 of Focke, Heinz, for “Pouch Made of a Single- or Multiple-Ply Synthetic Plastics Sheet Material, Preferably for TobaccoU.S. Pat. No. 3,510,053 The invention ”, provides a pouch made of a single- or multiple-ply synthetic plastics sheet material, particularly polyethylene, for the reception of a material such as tobacco. The pouch is preferably formed by longitudinally folding over a continuous sheet of plastic material, so that it has a short wall and a longer wall which latter serves as a wrap-around flap. The pouch is sealed at three edges and has an opening sealed by a substantially air-tight closure so constructed that it can be easily torn open.
U.S. Pat. No. 5,197,882 of Jernberg, Gary R. , for “Periodontal Barrier and Method for Aiding Periodontal Tissue Regeneration AgentsU.S. Pat. No. 5,197,882 A ”, discloses a periodontal barrier and method incorporating chemo-therapeutic agents is disclosed for aiding and guiding periodontal tissue regeneration.
U.S. Pat. No. 5,267,862 of Parker, Jonathan A. , for “Intraoral ApplianceU.S. Pat. No. 5,267,862 Dental ”, discloses dental appliances formed using this method provide with projections of the appliance itself which provide the necessary gripping forces rather than extraneous wires or other parts. The projections are formed by cutting grooves in casts of the teeth arches which will result in a projection, which will bear against the teeth, when the cast surface is duplicated in plastic. A first embodiment forms upper and lower plastic components, each having projections from the casts using the lost wax technique. These components are joined together in a predetermined relationship using a wax bit registration taken while the patient held his jaw in the predetermined relationship, and a dental articulator. A second method forms the plastic components directly over the casts. In this method the components are joined together, while mounted over the patient's arches, with the patient holding his jaw in the predetermined relationship. Both methods can be used to produce a single component with no joining of components then being required.
U.S. Pat. No. 5,326,685 of Gaglio, Thomas J. Santoriello, Luigi et al., for “Viscous Fluid Dispensing ApparatusU.S. Pat. No. 5,326,685 This is ”, discloses an applicator for applying a viscous fluid to a surface. There is a flexible backing material of a closed-cell material and a flexible dispensing material of an open-celled material disposed over and carried by the flexible backing material. The open-celled material has an internal structural spacing sized relative to the viscosity of the fluid, so as to absorb and allow the fluid to slowly pass therethrough. Preferably, the flexible backing material and the flexible dispensing material are sealed together about the periphery thereof to form a hollow pocket. The fluid in the form of a gel, salve or the like, is disposed in the hollow pocket. The pocket can be filled with an oxidizing agent and used for tooth whitening and/or gum treatment. The pocket can be attached to an adhesive backing to make adhesive bandages which apply various medications to the underlying skin area. This approach can be employed for treating wounds and blemishes. The pockets can also be used for dispensing a variety of other materials including makeup remover, moisturizer, polishes, cleansers and the like.
A primary object of the present invention is to provide a gum growth pad that will overcome the shortcomings of the prior art devices.
Another object is to provide a gum growth pad that fits snugly and comfortably between the gums and buccal mucosa, since it does not buckle or rotate when in place and does not interfere with speech.
An additional object is to provide a gum growth pad that will deliver medication at a controlled rate directly onto the gums, by diffusing slowly through a semi-permeable membrane and into the saliva.
A still additional object is to provide a gum growth pad that is placed high up or low down, abutting the junction between the buccal mucosa and the gum, to allow greater contact between the medication and the gum tissue, with less likelihood of the medication being swallowed.
A further object is to provide a gum growth pad that is simple and easy to use.
A still further object is to provide a gum growth pad that is economical in cost to manufacture.
Further objects of the invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
Various other objects, features and attendant advantages of the present invention will become more fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
FIG. 1 is a perspective view of a head and upper torso of a person with parts broken away, showing the instant invention in dotted lines in place.
FIG. 2 is a front view taken, in the direction of arrow 2 in FIG. 1, with the exterior of the head shown in phantom.
FIG. 3 is a side view taken in the direction of arrow 3 in FIG. 2, showing the outline of the head complete.
FIG. 4 is an enlarged elevational view of the instant invention per se.
FIG. 5 is a side view taken in the direction of arrow 5 in FIG. 4.
FIG. 6 is a further enlarged cross sectional view taken along line 6—6 in FIG. 4, showing the internal structure thereof.
FIG. 7 is a diagrammatic cross sectional view taken along line 7—7 in FIG. 1, showing the positioning of the instant invention between the buccal mucosa and the gums of the teeth.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views. FIGS. 1 through 7 illustrate a gum growth pad 10 comprising a nonporous first layer 12 with an absorbent second layer 14 placed upon the nonporous first layer 12. A medication 16 in a liquid form is impregnated within the absorbent second layer 14 and then dried. A semi-permeable third layer 18 covers the absorbent second layer 14 with the dried medication 16. A facility 20 is for sealing the nonporous first layer 12 to the semi-permeable third layer 18 about a periphery thereof. The medication 16ismay be a gum tissue growth substance 21. The nonporous first layer 12 is applied high up or low down against the gum tissue 26 of the teeth 28 in the mouth of a person 24, with the semi-permeable third layer 18 against the buccal mucosa 22. Saliva in the mouth of the person 24 will penetrate through to the semi-permeable third layer 18 and cause the dried gum tissue growth substance 21 in the absorbent second layer 14 to liquify and diffuse through the semi-permeable third layer 18, to enhance the growth of the gum tissue 26, reverse age related gum recession, protect against gingival disease and loss of teeth 28. The nonporous first layer 12 contributes stability, but allows flexibility, so that the pad 10 can adapt to the cavity without buckling or curling.
As best seen in FIG. 3, the nonporous first layer 12 is a synthetic thermoplastic sheet 30. The absorbent second layer 14 is a sponge-like cushion 32. The semi-permeable third layer 18 is a thin membrane sheet 34. The sealing facility 20 is a hot-bond adhesive 36.
The gum growth pad 10, as best seen in FIGS. 4 and 5, has an elongated generally tubular shaped body 38 with bulb shaped ends 40, to supply a large posterior area of the gum tissue 26 and help stabilize placement between the buccal mucosa 22 and the gum tissue 26 of the teeth 28. The nonporous first layer 12 is flat, while the semi-permeable third layer 18 is curved on the tubular shaped body 38, so as to fit snugly and comfortably between the buccal mucosa 22 and the gum tissue 26 in the mouth of the person 24.
The gum tissue growth substance 21 can be a drug diphenylantoin sodium known as by the trademark name DILANTIN, which is ordinarily used to treat and prevent seizures, with a well known side effect for gingival hyperplasia. DILANTIN has recently been shown to stimulate the formation of bone, as well as gum tissue.
The gum tissue growth medication 16 can also be an immuno-suppressant agent, such as cyclosporin or nifedipine. Immuno-suppressant agents are also known to stimulate gum growth. The gum tissue growth medication 16 can also be a nerve growth factor, a protein gene product, or a bone growth protein. Bone growth protein stimulates the repair of bone and tooth-anchoring connective tissue. All these substances have the potential of preventing and treating periodontal disease.
To use the gum growth pad 10, the following steps should be taken:
1. Apply the nonporous first layer 12 high up or low down against the gum tissue 26 of the teeth 28 in the mouth of the person 24.
2. Make sure that the semi-permeable third layer 18 is against the buccal mucosa 22.
3. The dried gum tissue growth substance 21 in the absorbent second layer will become liquified when saliva in the mouth of the person 24 penetrates through the semi-permeable third layer 18.
4. The liquified gum tissue growth substance 21 will diffuse through the semi-permeable third layer 18, to enhance the growth of the gum tissue 26.
5. The gum growth pad 10 will not interfere with speech and cause no discomfort.
6. Application of the gum growth pad 10, two to three times weekly, will regenerate the tooth anchoring connective gum tissue 26 to help protect against gingival disease.
