Embodiment approach

[0133] At present, manual undercut filling is mostly used, especially for automated large-scale production. Using manual undercut filling will undoubtedly reduce production efficiency. At the same time, manual undercut filling can not achieve the control of solid filling, thus affecting teeth. The effect of correction further affects the comfort of wearing. Therefore, the following embodiments are provided in this application, including the following:

[0134] see figure 1 , the first embodiment provides a tooth undercut model generation method, including steps S11-S15.

[0135] Step S11: Establish a digitized bounding box surrounding the digitized first tooth and the digitized second tooth; the positions of the digitized first tooth and the digitized second tooth are adjacent in the mouth.

[0136] In this embodiment, the digitized first tooth and the digitized second tooth are digitized jaw models acquired by a scanner, and are two digitized teeth adjacent to the digitized...

Abstract

The invention provides a tooth inverted recessed model generating method and device, a method for designing a shell-shaped tooth orthodontic appliance, electronic equipment and a computer storage medium. The method comprises the steps of establishing a digital surrounding box which surround two adjacent digital teeth; performing gridding processing on the digital surrounding box; establishing a dividing surface between the two digital teeth through points on the grid; acquiring a surrounding line of an inverted recessed filling area by means of the dividing surface; and generating the tooth inverted recessed model in the surrounding line of the inverted recessed filling area. According to the method, digital inverted recess filling is performed on the digital tooth model, thereby generating a digital dental jaw model. A manual operation is replaced by an automatic operation; production efficiency is improved; and standard operation is realized, thereby improving production quality ofthe shell-shaped tooth orthodontic appliance, and settling the problems of low manual inverted recess filling efficiency and no easy standard operation realization.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tooth undercut model generation method and device, a method for designing a shell-shaped dental appliance, a method for manufacturing a shell-shaped dental appliance, electronic equipment, and a computer storage medium. 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 orthodonti...
