Color partition type tooth preparation training model

Abstract

The invention discloses a color partition type tooth preparation training model. The color partition type tooth preparation training model is composed of tooth preparation training models corresponding to tooth positions, wherein each tooth preparation training model corresponding to each tooth position is composed of a fixed segment and a preparation training segment; the preparation training segment is of an integrated structure formed by combining target areas with the same material and different colors, an error allowable area and a prohibition area; the target area is an area which needsto be abraded during training; the error allowable area is an area which can be abraded during training; the prohibition area is an area which cannot be abraded during training; the error allowable area is positioned between the target area and the prohibition area and surrounds the target area. The tooth preparation training model is used for training, a trainee has a clear grinding target, training results can be fed back objectively in real time, errors caused by subjective factors of an instructor or an evaluator are avoided, and training standards are unified.

Description

technical field [0001] The invention belongs to the technical field of oral clinical medicine, and relates to a model for dental preparation training for professionals in the experimental teaching of oral medicine. Background technique [0002] In oral clinical work, tooth defects, tooth staining, uneven dentition, and cracked teeth caused by caries are common clinical problems. In the process of solving these problems, specific grinding (ie tooth preparation) of tooth tissue is required, and then restoration is carried out to achieve the purpose of treatment. Hand operation skills determine the handling ability of dentists, so in the training process of dental professionals, experimental teaching is one of the most important components. [0003] The traditional tooth preparation experiment teaching uses the teeth that have been lost or extracted (external teeth) for training, and its advantage is that the hand feeling during grinding is consistent with clinical operations....

AI Technical Summary

Problems solved by technology

The existing plastic teeth are mainly made of ordinary plastic. Its advantages are that the tooth shape is consistent with the human tooth shape, the anatomical structure is clear and typical, the same tooth position can be practiced repeatedly, and the price is reasonable. The disadvantage is that the grinding target is not enough during training. It is clear that the evaluation method can only be observed with the naked eye, which makes it difficult to make the evaluation results objective, which is not conducive to guiding the trainees to improve the accuracy of the operation step by step

However, it also has certain limitations. For example, the equipment for process evaluation is expensive (about 750,000 yuan per set, and one person and one machine are required for training), and the loading of the positioner leads to a significant increase in the weight of the rear of the turbine, which in turn affects the trainee’s The operation brings obvious influence, the probe signal is easily blocked and interrupted by the object, and the floor area is large, etc.; when the result evaluation equipment is working, the dental mold must be taken out and put into the scanner to affect the smoothness of the evaluation. After the evaluation, the trainees still I don’t know how to improve it, and the operation of the evaluation process is complicated
