Partial denture capable of being picked off and making technology thereof

Abstract

The invention discloses a partial denture capable of being picked off and a making technology thereof. The partial denture comprises a stent, artificial teeth and artificial gingiva, the stent comprises a clamping ring, a supporting ring, a big connecting body, a small connecting body and a saddle base plate; the saddle base plate is platy, makes contact with and covers the surfaces of gingiva without teeth; the artificial gingiva is arranged on the surface, away from the gingiva side, of the saddle base plate; artificial gingiva parts are arranged in the artificial gingiva. The making methodincludes the steps that oral cavity data of a patient is collected; through the oral cavity data, the step of constructing a model of the partial denture capable of being picked off overally is executed; based on the constructed model of the partial denture capable of being picked off overally, disc-shaped PEEK materials are cut at a time to obtain the partial denture capable of being picked off overally. In the scheme, the made denture is not cracked and falls off easily, is low in weight and free of peculiar smells, can be highly attached to the oral cavity of the patient, will not damage the mouth mocosa of the patient, can reduce the frequency of diagnosis of the patient, and can well protect remaining teeth well. The technology can be used for making the denture adapting to the oral cavity of the patient with high precision and rapidness.

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
