Problems solved by technology

[0006] However, how to quickly, effectively and stably reflect the accuracy of the student's bonding brackets is a long-term difficulty restricting the teaching: on the one hand, to evaluate a student's bonding brackets, it is necessary to evaluate the entire dentition. Judging the occlusal direction, mesio-distal direction, and axial inclination of up to 28 teeth requires a huge workload. Even experienced dentists need a long time to complete the judgment, not to mention the current oral Teratology teachers are limited, but there are many students; on the other hand, the evaluation methods at this stage mainly rely on the naked eye or use a ruler, and the repeatability of evaluations by different teachers is difficult to unify

Abstract

The invention provides a method for evaluating the in-vitro bonding accuracy of an orthodontic bracket through teaching. The method comprises steps of employing a device for evaluating the bonding accuracy of the orthodontic bracket through teaching, and the device comprises a virtual tooth model with a tooth root connecting piece, and a teaching evaluation pedestal for fixedly placing the virtual tooth model, the teaching evaluation base comprises a tooth root connecting groove and a plurality of auxiliary lines for evaluation, and evaluation point positions are arranged at the joints of the auxiliary lines for evaluation or the joints of extension lines of the auxiliary lines for evaluation. When the virtual tooth model is placed and fixed on the teaching evaluation base, the auxiliary line for evaluation and the evaluation point position at the joint of the auxiliary line for evaluation are used for quickly evaluating accuracy of the position of the bonding bracket on the dental crown of the virtual tooth model. When the number of the virtual tooth models is multiple, through the horizontal arrangement form of the virtual tooth models, compared with a traditional arch-shaped jaw frame, integral teaching evaluation can be carried out on brackets bonded to the virtual tooth models more visually, conveniently and rapidly.

Description

Technical field[0001]The present invention belongs to the field of oral tooth orthodontic technology, and more particularly to a method of teaching an in vitro adhesion accuracy of orthodontic brackets in the teeth, particularly for oral medical education, rapid evaluation of bonding accuracy of orthodontic bracket in vitro tooth.Background technique[0002]Fixed correction technology is the most accurate clinical application of correction techniques. Bracket is an important part of fixed correction technology, made of stainless steel or biopharae. In the current clinical treatment, whether it is a filament call or a straight wire bow technology, or personalization, it is necessary to transmit the arctic force generated by the bracket to control the three-dimensional movement of the teeth, reach orthodontic correction. the goal of.[0003]The accuracy of the bracket position during orthodontic treatment is an important role in the entire treatment process, and the accurate pilot adhesiv...
