Method for establishing auxiliary arch dynamic correction moment predicting model for downward pressing

Abstract

The invention discloses a method for establishing an auxiliary arch dynamic correction moment predicting model for downward pressing, wherein the method relates to the field of orthodontics treatmenttechnology. The method comprises the following steps of 1), analyzing a structure characteristic and a loading characteristic of an auxiliary arch for downward pressing; 2), establishing a side-view arc correction moment equation of the auxiliary arch for downward pressing; 3), establishing a front-view arch correction moment equation for downward pressing; 4), establishing a dynamic resistance model in a wax jaw dam simulation tooth moving process; and 5), establishing the auxiliary arch dynamic correction moment predicting model for downward pressing. The method can effectively perform parameterization expression on the auxiliary arch dynamic correction moment which is applied by a doctor for downward pressing, thereby accurately predicting the auxiliary arch dynamic correction moment which is applied by the doctor for downward pressing, assisting the doctor in improving safety and forseeability of orthodontics treatment, and improving digitalization degree in oral orthodontics treatment.

Description

technical field [0001] The invention relates to a method for establishing a prediction model of an auxiliary arch correction torque 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 magnitude of the orthodontic archwire used in each treatment stage and the prediction of the treatment effect are mostly judged based on the experience of the orthodontist. It can play a certain role in the treatment of most patients, but the orthodontic torque lacks quantitative standards, and the treatment results are complet...

Problems solved by technology

[0004] Although the current application of wax-made jaw embankment can improve the rationality of the orthodontic plan to a certain extent, the relationship between the shape of the orthodontic archwire and the dynamic orthodontic force on the teeth in the process of using base wax to simulate orthodontic treatment It has not been established and there is a lack of corresponding quantitative standards. Orthodontists are still unable to predict the magnitude of the orthodontic force of the patient under the influence of the orthodontic archwire through the simulation process. The model is used to parametrically express the dynamic correction torque value of the auxiliary arch for depression, which is of great significance for digital diagnosis and treatment of oral cavity and for assisting doctors to improve the safety and predictability of orthodontic treatment
