Embodiment 1

[0082] This embodiment provides a digital shell-shaped dental appliance design method, the flow chart of which is as follows figure 1 As shown, it specifically includes the following steps.

[0083] S100: Obtain a digital dental model;

[0084] S200: Obtain each single digital tooth model based on the digital jaw model, and perform preprocessing on each single digital tooth model to obtain a digital dentition model to be filled with undercuts;

[0085] S300: Generate the surface area of ​​the digital shell-shaped dental appliance to be filled with the undercut based on the digital dentition model of the undercut to be filled;

[0086] S400: Perform undercut filling processing on two adjacent digitized tooth regions in the surface area of ​​the digital shell-shaped dental appliance to be filled with undercuts, and generate a digital shell-shaped dental appliance containing undercut filling.

[0087] Through the above steps S100-S400, a digital shell-shaped dental appliance wi...

Embodiment 2

[0154] Based on Embodiment 1, this embodiment provides a digital shell-shaped dental appliance design system, the principle diagram of which is as follows Figure 6 As shown, it includes an acquisition module 100 , a preprocessing model 200 , a generation module 300 and an undercut filling module 400 .

[0155] Wherein, the obtaining module 100 is used to obtain a digital dental model, for example, the obtaining model 100 may be an intraoral scanner, which directly obtains the actual digital dental model in the patient's mouth.

[0156] The preprocessing module 200 is used to obtain each single digital tooth model based on the digital jaw model, and perform preprocessing on each single digital tooth model to obtain a digital dentition model to be filled with undercuts.

[0157] Specifically, the preprocessing module 200 includes a segmentation unit 201 and a preprocessing unit 202, wherein the segmentation unit 201 is used to perform segmentation processing on each single digi...

Embodiment 3

[0169] Based on Embodiment 1, this embodiment provides a method for designing a shell-shaped dental appliance, the flow chart of which is as follows Figure 7 As shown, it specifically includes the following steps.

[0170] S700: Obtain a digital dental model, where the digital dental model includes a digital dentition model.

[0171] S701: Design the orthodontic target position on the digital dentition model, and design a series of digital dentition models to be filled with undercuts gradually moving from the initial position to the orthodontic target position.

[0172] S702: Generate the surface area of ​​the digital shell-shaped dental appliance to be filled with undercuts based on the digital dentition model of the undercuts to be filled.

[0173] S703: Perform undercut filling processing on two adjacent digitized tooth regions in the surface area of ​​the digital shell-shaped dental appliance to be filled with undercuts to generate a digital shell-shaped dental appliance...

Abstract

The invention provides a design method, manufacturing method and system of a digital shell-shaped tooth appliance. The design method comprises the following steps: acquiring a digital dental model, obtaining each single digital tooth model based on the digital dental model, preprocessing each single digital tooth model to obtain a digital dentition model to be filled with undercut, generating a surface area of the digital shell-shaped dental appliance to be filled with the undercut based on the digital dentition model to be filled with the undercut, and performing undercut filling treatment ontwo adjacent digital tooth areas in the surface area of the digital shell-shaped tooth appliance to be undercut-filled to generate the digital shell-shaped tooth appliance containing undercut filling. By designing the digitized shell-shaped tooth appliance with the undercut filling function, manual undercut filling can be avoided, automatic preparation of the shell-shaped tooth appliance can be achieved, and then the production efficiency and quality of the shell-shaped tooth appliance can be improved.

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 design method, a manufacturing method and a system of a digital 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 ...
