JPS6041938Y2 - Simple complete denture - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a simple complete denture.

Conventionally, simple complete dentures have been made in the shape of natural teeth because it has been judged that the shape of natural teeth is the best.

However, in the case of complete dentures with a natural tooth shape like this, the occlusal surfaces of the molars are sloped, so if the upper and lower molars are biting together with even a slight deviation from side to side, the entire upper and lower dentures will shift from side to side. In addition to not being able to masticate reliably, large amounts of lateral pressure were applied to the gums, which sometimes caused pain.

In order to eliminate this problem, products are manufactured in which a metal ribbon bent in a zigzag pattern is embedded in the occlusal surface of molars of the same type as natural teeth, but since the metal ribbon is molded and embedded in the molars, the alignment of the teeth is affected. However, it required highly sophisticated manufacturing technology and was expensive.

Therefore, the present invention solves the above drawbacks at once by forming the molars with continuous metal teeth with a flat occlusal surface and multiple grooves, and by attaching plate-shaped anterior teeth to the cleft side of the continuous metal teeth. The purpose of this project is to provide a simple complete denture that not only improves the appearance of the teeth, but also has new advantages.

Hereinafter, one implementation of the present invention will be described in detail based on the drawings.

In the simple complete denture 1 shown in the drawing, 2 is an upper denture and 3 is a lower denture.

Both dentures 2 and 3 are integrally implanted on synthetic resin floors 4 and 5, respectively.

6.6 is a metal continuous tooth corresponding to the first premolar, second premolar, and first molar of the upper jaw, and has a flat occlusal surface 6a and a plurality of grooves 7, 7, and 7 on the occlusal surface 6a. ... are installed in parallel.

The continuous teeth 6, 6 are integrally implanted in the floor 4 at positions corresponding to the first premolars to the first molars.

8.8 is a continuous metal tooth corresponding to the first premolar, second premolar, and first molar of the lower jaw, and has a flat occlusal surface 8a and a plurality of grooves 9, 9 on the occlusal surface 8a. ... are installed side by side.

These continuous teeth 8, 8 are integrally implanted on the floor 5 between the first premolar and first molar at positions corresponding to the molars.

The continuous metal teeth 6, 6 on the upper jaw and the corresponding continuous metal teeth 8, 8 on the lower jaw are formed in such a way that the grooves 7, 9 intersect with each other to improve the efficiency of mastication. I'm trying to increase it.

10 is a plate-shaped front tooth, each metal continuous tooth 6゜6.8.8
The tips are attached at positions corresponding to the first premolar portion 11, the second premolar portion 12, and the first premolar portion 13 of the occlusal surfaces 6b, 8b so as not to protrude from the occlusal surfaces 6a, 8a.

The simple complete denture 1 constructed as described above uses continuous metal teeth 6, 8 as molars, the occlusal surfaces 6a, 8a of which are flat and have grooves 7, 9, and the occlusal surfaces 6a, 8a are inclined. Therefore, even if the upper and lower continuous metal teeth are shifted from side to side during meshing, no lateral force will be generated.

Therefore, the upper and lower dentures 2 and 3 do not move from side to side 1, and since the grooves 7 and 9 are provided, it is possible to masticate reliably, and there is no lateral pressure applied to the gums, which prevents them from becoming painful. There isn't.

Furthermore, plate-shaped front teeth 10 are attached to the round sides 6b, 8b of the metal continuous teeth 6, 8, so that the appearance is good.

Moreover, since the metal continuous teeth 6 and 8 are formed separately from the plate-shaped front teeth 10, they can be easily molded, and the front teeth can be easily arranged and provided at low cost.

Claims (1)

[Scope of Claim for Utility Model Registration] A complete denture in which the denture is integrally implanted on a base made of Hewei resin, the positions of which correspond to the first premolar, second premolar, and first molar of the complete denture. Then, continuous metal teeth corresponding to each of these teeth are integrally implanted, and these continuous metal teeth are formed into a flat occlusal surface, and multiple grooves are arranged in parallel on the occlusal surface. A simple complete denture characterized in that plate-shaped front teeth are attached to the positions corresponding to the first premolar part 1, the second premolar part, and the first premolar part on the cleft side of the continuous teeth.
