Abstract

The present invention discloses an establishing method for a depressed auxiliary arch tooth rotation angle prediction model and relates to the technical field of orthodontic treatment. The establishing method comprises the following steps: 1) analyzing structural features and loading characteristics of a depressed auxiliary arch; 2) establishing a lateral view arc correction torque equation of thedepressed auxiliary arch; 3) establishing an anterior view arc correction torque equation of the depressed auxiliary arch; 4) establishing a dynamic resistance model in a wax jaw ridge simulated tooth movement process; and 5) establishing the depressed auxiliary arch tooth rotation angle prediction model. The establishing method for the depressed auxiliary arch tooth rotation angle prediction model can provide parameter supports for physicians to use the depressed auxiliary arch to correct high-angle type overlying jaws, assists doctors to improve safety and predictability of the orthodontictreatment, and improves digitization degrees of the oral cavity orthodontic treatment.

Description

technical field [0001] The invention relates to a method for establishing a prediction model of a tooth rotation angle of an auxiliary arch for depression, and belongs to the technical field of orthodontic treatment. Background technique [0002] Overbite is a specific form of malocclusion that is relatively common in oral clinical practice, and it usually has a great impact on the occlusal relationship of patients. The auxiliary arch for depression is a commonly used arch for high-angle overbite cases in clinical practice. The shape of the orthodontic archwire is the decisive factor affecting the orthodontic torque. In the traditional diagnosis process, the orthodontic arch wire correction rotation angle and the prediction of the correction effect in each stage of correction are mostly judged based on the experience of orthodontists. The treatment of most patients can play a certain role, but there is no quantitative standard for the rotation angle of orthodontic treatment...
