Abstract

The invention provides an inspection method of a shell-shaped dental appliance based on computer finite element analysis. The inspection method comprises the steps of: acquiring a finite element modelof a dentition; acquiring a finite element model of the shell-shaped dental appliance; acquiring picking parameters of the shell-shaped dental appliance; performing finite element analysis on the picking of the shell-shaped dental appliance worn on the dentition based on the finite element model of the dentition, the finite element model of the shell-shaped dental appliance and the picking parameters of the shell-shaped dental appliance, and acquiring finite element analysis results including at least one of a picking force and local stress of the shell-shaped dental appliance during the picking process; and determining whether the shell-shaped dental appliance is qualified based on the finite element analysis results.

Description

technical field [0001] The present application generally relates to inspection methods for shell-like dental instruments based on computer finite element analysis. Background technique [0002] Today, shell-shaped dental instruments made of polymer materials are becoming more and more popular. Shell-shaped dental appliances include, but are not limited to, orthodontic appliances and retainers. [0003] For the retainer, it is hoped that the removal force is appropriate so that it is easy to remove and not easy to fall off. [0004] For the orthodontic appliance, it is hoped that it has sufficient force to effectively and quickly realize the orthodontic treatment of the teeth, and it is also convenient to take off and wear. However, applying too much force may make it difficult to remove the aligner. In order to make the appliance easy to remove and wear, it is necessary to control the removal force, that is, the force required to remove and wear the appliance, within a re...
