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

Embodiment 1

[0049] Such as Figure 7-11 As shown, this embodiment discloses a removable partial denture, which includes a bracket 10A, an artificial tooth 30 and an artificial gingiva 60, and the bracket 10A includes a clasp 101, a rest 102, a large connecting body 103, a small connecting body and Smoothly connect the saddle base plate 104 of the large connecting body 103; the effect of smooth connection is equivalent to the saddle base plate 104 being a plate-shaped body extending from the large connecting body 103 to both sides; the saddle base plate 104 is plate-shaped and tightly covered on the patient The surface of edentulous gingiva 40 forms the substrate 104 of artificial gingiva 60 ;

[0050] Such as Figure 11 and 12 As shown, the bracket 10A, the artificial tooth 30 and the artificial gingiva 60 are integrated, that is, the three parts are processed as a whole. Such as Figure 1-6 It is the structural diagram of the removable partial denture in the existing design, and the p...

Embodiment 2

[0052] Such as Figure 8 As shown, this embodiment specifically discloses the structure of the artificial gingiva 60 in the above-mentioned embodiment: the shape of the artificial gingiva 60 is consistent or similar to that of the patient's gingiva 40 . Specifically, the convexity of the root of the artificial gingiva 60 is consistent with the convexity of the root of the patient's oral cavity. This makes the shape of the denture 1 consistent with the patient's oral cavity, more like the patient's "native" teeth 70, and the use experience is better. The artificial gingiva 60 is provided with a gingival papilla 601 between every two adjacent artificial teeth 30 , or at both ends of the artificial gingiva 60 . Whether to take the end depends on the location of the artificial gingiva. If it is at the non-gum end, it includes both ends. If it is at the end, the gingival papilla may not be involved at the end. This makes no gaps are left between the artificial teeth, preventing f...

Embodiment 3

[0054] Such as Figure 13 As shown, this embodiment discloses a method for manufacturing an integral removable partial denture, comprising the following steps:

[0055] A. The step of collecting oral data of the patient, the oral data includes oral model data and occlusal relationship data;

[0056] B. A step of constructing an overall denture model through the oral cavity data, the overall denture model is an overall model including three parts of the bracket 10A, the artificial tooth 30 and the artificial gingiva 60;

[0057] C. Based on the constructed integral denture model, the disc-shaped PEEK material was cut to obtain an integral (one-piece) removable partial denture.

[0058] This embodiment discloses a method for collecting oral data of a patient, that is, obtaining an impression of the patient clinically, or scanning the oral cavity of the patient to collect the oral data of the patient. Dental data are also used in the determination of orthodontic solutions. ...

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 ...
