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 teaching and evaluating the bonding accuracy of orthodontic brackets outside the body. The method includes using a device for teaching and evaluating the bonding accuracy of orthodontic brackets. The virtual tooth model of the component and the teaching evaluation base for fixedly placing the virtual tooth model, the teaching evaluation base includes the tooth root connection groove and the auxiliary line for evaluation, the auxiliary line for evaluation is multiple and its junction or The intersection of extension lines is the evaluation point. When the virtual tooth model is placed and fixed on the teaching evaluation base, the auxiliary line for evaluation and the evaluation point at its junction are used to quickly evaluate the accuracy of the bonding bracket position on the crown of the virtual tooth model. And when there are multiple virtual tooth models, through their horizontal arrangement, compared with the traditional bow-shaped jaw frame, it is more intuitive and convenient to carry out overall teaching evaluation on the brackets bonded to multiple virtual tooth models .

Description

technical field [0001] The invention belongs to the technical field of oral orthodontics, and in particular relates to a method for teaching and evaluating the bonding accuracy of orthodontic brackets in vitro, especially for convenient and rapid evaluation of the bonding accuracy of orthodontic brackets in vitro in stomatology education. Background technique [0002] Fixed orthodontic technology is currently the most widely used clinical orthodontic technology with the most reliable orthodontic effect. Bracket is an important part of fixed orthodontic technology, made of stainless steel or bioceramics. In the current clinical treatment, whether it is square wire arch or straight wire arch technology, or personalized orthodontic treatment, it is necessary to transmit the orthodontic force generated by the arch wire with the help of brackets, so as to control the three-dimensional movement of teeth and achieve orthodontic treatment. the goal of. [0003] In the process of o...
