Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Embodiments of the present invention and its specific implementation process are as follows:

[0034] figure 1 For the cut and repaired tooth model to be processed, obtain the points at the junction of the teeth and gums, and perform interpolation to obtain figure 2 The series of points shown. At this point, connect the points to get the gingival boundary line corresponding to each tooth.

[0035] B. Draw the lines between the teeth:

[0036] B1. For every two adjacent tooth models, select the six points closest to the interdental gap from the vertices of the connection between the tooth model and the gingival model obtained in step A as the interdental points, and one of the tooth models is from the interdental to the interdental The middle part of the tooth is recorded as point a1 to point a6 in turn, and the other tooth...

Abstract

The invention discloses a digital gum line extracting method. The digital gum line extracting method comprises the following steps: acquiring vertexes of joints of tooth models and gum models, carrying out interpolation, and sequentially connecting the vertexes and the interpolating points to obtain gum boundary lines; constructing connecting lines between two adjacent tooth models, and connecting the gum boundary lines of the two adjacent tooth models through the connecting lines to form a gum line; carrying out treatment on the gum boundary lines of the last tooth models ( posterior molar) on the two sides of a tooth jaw model; and carrying out smoothing treatment on the gum line by adopting a Snake fitting method. According to the digital gum line extracting method, the gum lines are rapidly, efficiently, accurately and automatically generated, so that the accuracy and work efficiency are improved, the complicated interactive process is avoided, the boundaries of the gum lines are smooth, and the method is used for the automatic and efficient tooth socket polishing.

Description

technical field [0001] The invention relates to the field of digital oral cavity, in particular to a digital gum line extraction method. Background technique [0002] In recent years, digital oral technology has developed rapidly, and invisible orthodontics have gradually become popular. In the current process, after the appliance is laminated, it needs to be manually polished to make the edge of the appliance fit the edge of the teeth, so as to avoid the abrasion of the appliance on the gums. However, the efficiency of manual grinding is low, and it takes a long time to polish a pair of braces; and there is also a certain lack of precision, which is prone to mistakes that cause the braces to be inappropriate or damaged. Contents of the invention [0003] In order to solve the problems existing in the background technology and improve work efficiency and grinding accuracy, the present invention provides a digital gum line extraction method to provide a data basis for auto...
