A method of making mandibular half-denture with silicone rubber pressure impression

Abstract

The invention discloses a method for making a mandibular half-denture with a silicone rubber pressure impression. Firstly, individual trays that cross the edge line are made, and then a hand-adjustable silicone rubber weight is placed in the mouth. , to get the first impression, and then inject the gun-mixed silicone rubber heavy body or middle body into the first impression and the mouth respectively, put the first impression in the inlet, press it in place, take out the impression after curing, and then get the mandibular dentures. In the present invention, a hand-adjustable silicone rubber weight is combined with a gun-mixed silicone rubber weight or middle body with slightly poor fluidity to push away the mucous membrane, stretch it excessively, and perform a pressure function impression to make a horizontal impression of bone tissue to obtain internal and external Oblique lines and other mandibular surface contours, thus solving the problem of dentures made of traditional alginate impressions that are prone to tenderness and even alveolar crest migration pain, and it can be used for the preparation of dentures for patients with severe and extremely severe bone resorption .

Description

technical field [0001] The invention belongs to the technical field of oral restoration, and in particular relates to a method for making a mandibular half-denture by a silicone rubber pressure impression. Background technique [0002] According to the degree of resorption of the remaining alveolar bone, dentition loss is divided into four types: mild, moderate, severe, and extremely severe. At present, the popular adsorption denture is prepared by the alginate impression method, which is a pressure-free impression at the soft tissue level, and mild and moderate patients with more keratinized gingiva can obtain good retention and The success rate, but for severe and very severe patients with less keratinized gingival retention or even non-keratinized gingival retention, there are disadvantages such as poor retention, and traditional non-functional pressureless impressions cannot show the patient's oral softness and hardness When the tissue is subjected to functional movemen...

AI Technical Summary

Problems solved by technology

The currently popular adsorptive dentures are prepared by the alginate impression method, which produces a pressure-free impression at the soft tissue level, and mild and moderate patients with more keratinized gingiva can obtain good retention and However, for severe and extremely severe patients with less keratinized gingiva or even no keratinized gingiva, there are disadvantages such as poor retention, and the traditional non-functional pressure-free impression cannot show the softness and hardness of the patient's mouth When the tissue is subjected to functional movement, the supporting tissue of the denture base and mucosal soft tissue will be damaged under the condition of functional movement, resulting in migratory pain on the alveolar crest

As a result, patients need repeated visits to grind away these tender points, which becomes a nightmare for both patients and doctors

At the same time, adsorption dentures require edge shaping to improve the retention of the complete denture, but even skilled doctors need at least 1 hour to complete the edge shaping of the full mouth, which is time-consuming and labor-intensive
