(Cl. 18-5.7)
The present invention relates to a device for providing a cavity in a molded denture for the purpose of receiving a suction-cup adhering device.
The cavity is located on the surface of the denture which engages the mucous membrane of the mouth. The cavity is adapted to receive and retain a suction-cup device formed entirely of resilient material in such a manner that the active edges of the suction-cup are eliectively liush with the surface of the denture. This causes the denture to be more comfortable than conventional dentures equipped with suction-cups.
Briefly, the device of invention comprises a cylindrical body having a tapered tail-piece which is adapted to be inserted in the mold or model from which the denture is to be made. The tail-piece extends from a cylindrical body, an annular flange being disposed between the tailpiece and the body. A cup-shaped socket member is detachably mounted on the body and forms a part of the completed denture when it is removed from the mold. This cup-shaped member serves as a socket for receiving and firmly holding a central projecting knob portion of the liexible suction-cup. A stack of flexible discs is clamped'between the flange and the cup-shaped socket. The number of discs included in the stack determines the depth of the outer portion of the cavity which receives and surrounds the cup portion of the suction-cup.
The invention will be more fully understood by reading the following specilication with reference to the accompanying drawing forming a part hereof.
Referring to the drawing:
Figure 1 is an exploded perspective view showing an embodiment of the invention.
Figure 2 is a perspective view showing the device of Fig. 1 assembled for use.
Figure 3 is a side elevational view, partly in section, showing a modied form of the invention.
Figure 4 is a perspective view which shows two of the devices mounted on a mold or model from which the denture is to be made.
Figure 5 is a sectional view taken along the line V-V y of Fig. 4.

terior of which the ball shaped projection, or central knob 3 of a suction cup 4, can be inserted.
The central knob portion 3 permits the suction-cup 4 to be fixed in a cavity 5 (Fig. 6), the knob 3 being held securely in the socket member 2. The cavity 5 is of such dimensions that the suction-cup 4 will be completely enclosed within the cavity 5 when the suction-cup 4 is llattened for adherence to the mouth of a wearer of the denture 1. Thus, the presence of the suction-cup 0 4 is not felt by the wearer.
The cavity 5 is formed and the socket member 2 is fixed in the denture by means of the device which is the subject matter of the present invention.
This device comprises a cylindrical body 7 from which a tapered tail-piece 8 extends. An annular ange 7' is disposed between the body 7 and the tail-piece 8. The rigid cup-shaped socket member 2 is detachably secured to and surrounds the `body 7. A stack of superposed flexible discs 9 is clamped between the socket member 2 and the ilange 7.
A hole is drilled in the model 10 (Fig. 4) and the tail piece 8 is secured therein by means of a special cement. The stack of flexible discs 9 is caused to adhere to the surface of the model 10 as shown in Fig. 5. The denture 1 is then formed using the model in the usual manner.
When the denture 10 is completed, the socket member 2 will remain iixed in the center of the cavity 5 for engagement by the central knob portion 3 of the suctioncup 4 as shown in Fig. 6. The depth of the cavity 5 is determined by the number of discs 9 which are assembled in stacked relationship on the body 7.
In a modified form of the invention, as shown in Fig. 3, the body 7 is provided with a pin 6 which extends through the bottom of the socket member 2. The pin 6 serves to secure the socket member 2 detachably to the body 7 as by a force lit or a light soldering of the pin 6 to the socket member 2.
I claim:
1. A device of the character described for forming a cavity in a denture for receiving a suction cup adhering device comprising a cylindrical body with a tapered tail piece, an annular flange between the body and tail piece, a rigid cup-shaped socket member detachably mounted on and surrounding the body, and at least one disc clamped between the cup-shaped member and flange.
2. A device of the characterdescribed for providing a cavity in a molded denture for receiving a suction cup adhering device, said first-named device comprising a cylindrical body, a tapered tail piece extending from said body, an annular flange disposed between said body and said tail piece, a rigid cup-shaped socket member detachably secured to and surrounding said body, and a stack of superposed flexible discs clamped between said cupshaped member and said llange.
3. A device according to claim 2, further comprising a pin extending axially between said body and said cupshaped member.
