Abstract

The invention discloses a design method and a forming method of a reinforcing part adding position, a storage medium and a system. The design method comprises the following steps: acquiring a dental digital model; calculating a reference value of an inertia moment of a surface target area of the digital tooth jaw model relative to the rotating shaft; and judging the reference value and a first threshold value, if the reference value is smaller than the first threshold value, recording at least partial region of the target region as a reinforcing part adding position, and if the reference value is not smaller than the first threshold value, not recording. The reference value of the inertia moment of the target area on the surface of the digital dental model relative to the rotating shaft can be used for representing the inertia moment of the corresponding area of the formed dental orthodontic appliance relative to the rotating shaft, and the inertia moment is used for representing the bending resistance of the dental orthodontic appliance. A convex ridge can be formed in a corresponding area of the dental orthodontic appliance subsequently, so that deformation or fracture is avoided; in addition, the adding position of the reinforcing part is determined by directly calculating the inertia moment of the target area, and selection of the adding position of the reinforcing part is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a design method, a forming method, a storage medium, and a system for adding a reinforcement part. Background technique [0002] During the use of orthodontic appliances, additional force needs to be applied to realize the repeated wearing and removal of the orthodontic appliances. When the external force is large, the orthodontic appliances may be deformed or broken, affecting the dental The use of orthodontic appliances may make dental orthodontic appliances unable to achieve the corrective effect. Contents of the invention [0003] The purpose of the present invention is to provide a design method, a molding method, a storage medium, and a system for adding a reinforcement part, which can greatly simplify the process of adding a reinforcement part to a digital model of a tooth and jaw through a reasonable design method for adding a reinforcement part. And the formed de...
