A removable partial denture and its manufacturing process

Abstract

The invention discloses a removable partial denture and its manufacturing process. The denture includes a bracket, artificial teeth and artificial gingiva, and the bracket includes a clasp, a rest, a large connecting body, a small connecting body and a saddle base; the saddle base is a plate shape, contacting and covering the surface of edentulous gingiva; the artificial gingiva is arranged on the surface of the saddle base plate away from the gingiva; the artificial tooth root is arranged in the artificial gingiva. The production method is as follows: collecting oral data of the patient; constructing an integral removable partial denture model through the oral cavity data; based on the constructed integral removable partial denture model, cutting the disc-shaped PEEK material at one time to obtain the integral removable partial denture. The denture produced by the scheme of the present invention is not easy to split and fall off, has a light texture and no peculiar smell, has a high degree of fit with the patient's oral cavity, does not damage the patient's oral mucous membrane, can reduce the number of times the patient visits a doctor, and has a good protective effect on the patient's remaining teeth. The technique of the invention can manufacture dentures adapted to the patient's oral cavity with high precision and quickly.

Description

technical field [0001] The invention relates to the field of removable partial dentures, in particular to a removable partial denture and its manufacturing process. Background technique [0002] Removable partial denture restoration is a method of repairing missing dentition, such as Figure 1-6 As shown, traditional (existing) removable partial dentures are generally composed of metal brackets, plastic bases, and plastic artificial teeth, wherein the brackets are composed of snap rings, large and small connectors, and rests. The manufacturing method of the traditional removable partial denture is: separately process the entities of three parts (metal bracket, plastic base, plastic artificial teeth) and connect them together. [0003] Traditional removable partial dentures have the following disadvantages: 1. The processing technology is relatively complicated, involving the design and production process of brackets, the process of arranging artificial teeth, the process of ...

AI Technical Summary

Problems solved by technology

[0003] Traditional removable partial dentures have the following disadvantages: 1. The processing technology is relatively complicated, involving the design and production process of brackets, the process of arranging artificial teeth, the process of filling glue, etc.; 2. The production cycle is long, and each component needs to be tried on by the patient Then add and assemble subsequent components; 3. The user experience is poor. The clinical steps include try-on brackets, try-on wax models, etc. The patient has visited the doctor many times, and the traditional dentures have a metallic and gluey smell, and the dentures are heavy. 4. Due to the assembly of each entity, there are weak parts in the traditional denture structure (such as metal-base resin bonding interface, base resin-artificial tooth bonding interface), when the occlusal force is large Or when the structural design is improper, these weak parts may break, split or fall off; 5. In the process of filling the plastic base, since the metal mesh needs to be fixed in the base, if the design of the bracket completion line is improper (that is, large The joint between the connecting body and the metal mesh) or incomplete filling may cause the denture tissue surface to be unsuitable, and the denture production failure
