Problems solved by technology

[0003] At present, there is no plaster model of tooth defect or dentition defect that is very suitable for teaching when students are conducting oral experiments. Students need to modify the standard tooth model to make a tooth model of defect, and different cases need to be done. Multiple tooth models can then be used for the practice of restoration production. The standards of the students after trimming are not uniform, and some cannot even be used, which seriously affects the teaching quality and efficiency of the experimental class.

preparation example Construction

[0034] The preparation method of the tooth silicone negative mold comprises the following steps:

[0035] Step 1: Trimming part of the teeth of the complete dental gypsum model, trimming the teeth into the shape of the abutment teeth required for the production of the corresponding restorations, and obtaining a case tooth working model that combines the shapes of the abutment teeth required for the production of various restorations.

[0036] The tooth working models of the cases include three types: models for making fixed dentures, models for making removable partial dentures and models for making complete dentures.

[0037] The model for making fixed dentures is as follows: Figure 1-2 As shown, including maxillary model 1 and mandibular model 5, experienced clinicians use high-speed mobile phones to trim the complete tooth plaster model into a set of tooth models with various abutment tooth shapes required for making restorations. The tooth part of the plaster model of th...

Abstract

The invention relates to a preparation method of a tooth model for a student experiment. A tooth silica gel female mold gathering various need-to-be-manufactured restoration bodies of various tooth cases is manufactured in advance, gypsum is poured into the pre-prepared tooth silica gel female mold, after the gypsum is solidified, the gypsum and the tooth silica gel are separated, so that the tooth model for the student experiment is obtained. The tooth model prepared by the preparation method is uniform in standard, high in quality, convenient for mass production, and is suitable for studentexperiments.

Description

technical field [0001] The invention relates to the technical field of oral cavity experiments, in particular to a method for preparing a tooth model for student experiments. Background technique [0002] In the existing experimental teaching of stomatology and stomatology technical professional courses, various forms of tooth defects, dentition defects and plaster models of dentition loss are required for students to use in experimental courses. For example, inlays, all-ceramic veneers, cast crowns, porcelain crowns, all-ceramic crowns, fixed bridges, anterior teeth integrated post and core, posterior teeth split post and core, etc. Plaster models, models of dentition defects of different Ken's classifications, edentulous plaster models of different alveolar ridge conditions, etc., students need to use different plaster models for the design and production of restorations. Especially for students majoring in stomatology technology, they need to practice repeatedly on plast...
