Abstract

The invention discloses a preparation method of a shell-shaped tooth appliance. The preparation method comprises the steps: acquiring a digital dental jaw model; segmenting a digital dental jaw modelbody; repairing a single digital dental crown model; performing digital undercut filling; and designing a digital shell-shaped tooth appliance and preparing the shell-shaped tooth appliance. The shell-shaped tooth appliance is prepared by adopting the method; according to the shell-shaped tooth appliance, the digital dental jaw model is digitalized, so that manual operation can be saved, the design accuracy is improved, and the treatment accuracy, the wearing comfort and the wearing durability of the prepared shell-shaped tooth appliance are directly influenced when the shell-shaped tooth appliance is manufactured by adopting an additional material.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a preparation method of a shell-shaped dental appliance. Background technique [0002] Orthodontic treatment of teeth through shell-shaped dental appliances is more and more accepted by patients, because it is beautiful, comfortable and convenient for patients to take off and wear by themselves. Shell-shaped dental appliances are designed according to the patient's oral situation. The virtual orthodontic plan prepares a shell-shaped dental appliance that can reposition the teeth from the first layout to the second layout. The prepared shell-shaped dental appliance is a series of polymer shell-shaped devices that gradually adjust the tooth layout. When the patient wears the shell When using the shape orthodontic appliance, the patient's teeth can be rearranged and gradually changed to the target orthodontic position. [0003] Since the production of shell-shaped orthodontic appliance...
