Pressure accessory design method and system, appliance forming method and storage medium

Abstract

The invention discloses a pressure accessory design method and system, an appliance forming method and a storage medium. The method comprises the following steps: acquiring an initial digital tooth jaw model; obtaining a target digital appliance model containing a pressure accessory; wearing the target digital appliance model on the initial digital tooth jaw model, wherein the pressure accessory applies force to teeth to be corrected; calculating at least one of the resultant moment, the low pressure force and the deformation of the target digital appliance model borne by a to-be-corrected teeth; and judging whether the pressure accessory is qualified according to a calculation result. The design of the pressure accessory can be guided and optimized through simulation of a computer, and the force application condition of the finally-formed dental orthodontic appliance on actual teeth to be corrected can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a design method of a pressure accessory, a forming method of an orthodontic device, a system and a storage medium. Background technique [0002] In the process of orthodontic treatment, for some special cases, it may be necessary to set some pressure accessories to cooperate with the appliance, so that the appliance can apply a predetermined force and / or moment to the dentition according to the design, but there is currently no set Mature methods to guide the design of pressure accessories are mainly based on the experience of clinicians or technicians to design and add pressure accessories, which may not fully achieve the expected results. [0003] In view of the above, it is necessary to provide a design method for pressure accessories to guide and optimize its design. Contents of the invention [0004] The purpose of the present invention is to provide a pressure acces...
