Abstract

The invention provides a process data optimization method of a shell-shaped dental appliance making process based on the hot-pressing film molding technology. The process data optimization method comprises obtaining a first set of process data of the shell-shaped dental appliance making process based on the hot-pressing film molding technology; obtaining a first shell-shaped dental appliance geometric shape through calculation based on the first set of process data; modifying the first set of process data based on the first shell-shaped dental appliance geometric shape in order to at least partially offset the deviation between the first shell-shaped dental appliance geometric shape and the design and caused by elastic-plastic deformation in the shell-shaped dental appliance making process, and obtaining a second set of process data.

Description

technical field [0001] The present application generally relates to a computer-aided process data optimization method for the manufacturing process of shell-shaped dental instruments based on thermal compression film forming technology. Background technique [0002] Shell-shaped dental orthodontic appliances based on polymer materials are becoming more and more popular due to the advantages of aesthetics, convenience, and ease of cleaning. [0003] At present, shell-shaped dental instruments (including but not limited to orthodontic appliances and retainers) are generally produced based on a hot-pressed film forming process. Due to the complex thermal-mechanical coupling effect, the dynamic distribution of the temperature field during the hot pressing film forming process directly affects the total internal stress (residual stress) level of the shell-shaped dental instrument after cooling and solidification, and when the shell-shaped dental instrument is cut and separated A...
