Abstract

The invention discloses a tooth appliance production method and device. The method comprises the steps of making a tooth appliance model according with the shape of patient teeth, forming an injection molding cavity in a shape same as that of the tooth appliance model in a mold, forming an injection molding hole and an exhaust hole communicated with the injection molding cavity, injecting molten raw materials into the injection molding cavity through the injection molding hole, and taking out the molten raw materials after cooling shaping to obtain a tooth appliance. Due to the fact that a membrane with fixed thickness is not adopted, the thickness of the tooth appliance model can be adjusted as needed during injection molding, and then local strength of the tooth appliance can be adjusted. Meanwhile, due to the adoption of injection molding, release of internal stress is reduced, the precision of the tooth appliance is improved greatly, and tooth correction effect is better.

Description

technical field [0001] The invention relates to the technical field of dental diagnosis and treatment, in particular to a production method and device of a dental appliance. Background technique [0002] With the improvement of the quality of life, people have higher and higher requirements for the beauty of teeth. Tooth irregularity or abnormal shape is an important reason for damaging the beauty of teeth, and it is also a very common case in clinical oral treatment. During orthodontics, patients wear aligners over their teeth to treat misaligned or abnormally shaped teeth. [0003] The accuracy of the orthodontic appliance directly affects the fit between the orthodontic appliance and the patient's teeth, which in turn affects the effect of orthodontics. In the prior art, the orthodontic appliance generally adopts a production method of thermoplastic molding. Specifically, a diaphragm with a standard thickness is used as the raw material for production, and the diaphragm...
