A film-pressing system and method for producing shell-shaped dental appliances

Abstract

The present invention is a lamination system for producing shell-shaped dental appliances, comprising: a production management server acquires lamination process parameters of shell-shaped dental appliances from a case information storage according to user identification information, and sends lamination commands to a control device; the control device controls the movement of the feeding assembly and simultaneously picks up the diaphragm and the dental model assembly, and sends them to the first station and the second station. The first station and the bearing table move to the second station, and the heating device is further controlled to heat the membrane according to the predetermined process parameters; after the heating is completed, the bearing table is controlled to move from the second station to the first station and the heating device Move away from the first station; control the second lifting module to drive the carrier platform carrying the dental model assembly to rise, and control the lamination assembly to press the heated diaphragm on the dental model assembly according to the lamination process parameters.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and more precisely relates to the manufacturing technology of a shell-shaped dental appliance, in particular to a film-pressing system and method for producing a shell-shaped dental appliance. Background technique [0002] In the existing technology of preparing shell-shaped dental appliances, it generally includes obtaining a digital model in the patient's mouth, 3D printing the dental model, cleaning the dental model, curing the dental model, pressing the film, artificial stripping, cutting, polishing, shell-shaped Orthodontic appliance cleaning, inspection, packaging and other processes. Among them, the film pressing process is an important part of the preparation of shell-shaped dental appliances. In this process, the diaphragm is heated, and then it is pressed onto the dental model through positive or negative pressure, that is, the shell corresponding to the dental model is formed. Sh...

Problems solved by technology

The work efficiency of manual lamination is low, and the productivity cannot be increased on a large scale, and the manual labor intensity is high, or the semi-automated process is adopted, the dependence of manual operation is relatively strong, and the production is not automated, so the production efficiency is relatively low. In addition, Manual operation results in uneven production of orthodontic appliances, which cannot meet the existing needs; at the same time, manual operation and semi-automatic operation, manual acquisition of lamination process parameters, resulting in a relatively high error rate, and the effect of orthodontics on patients in the later stage is not ideal. Based on the above, It is of great significance to construct a pressure film system for the production of shell-shaped dental appliances
