Embodiment Construction

[0042]The present invention will be further described in detail below in conjunction with specific embodiments.

[0043]Such asfigure 1 As shown, the method for automatically generating an ideal dental model of the present invention includes the following steps:

[0044]Step 1) Perform feature extraction on the digital three-dimensional dental model to determine the ideal dental arch feature line of the model. First determine the patient's mandibular ideal dental arch feature line SL, and then determine the patient's upper jaw ideal dental arch feature line SU. To obtain the ideal dental arch feature line, the first step is to extract the shape features of the patient's jaw. These features can be obtained by fitting the feature points on each tooth or several teeth in the jaw, or from the gingival tissue of the digital three-dimensional dental model The feature extraction is obtained, and these feature points constitute the control point set that generates the ideal dental arch feature li...

Abstract

The invention discloses an automatic generation method of a digital dental ideal model. The present invention determines the ideal dental arch feature line of the patient by extracting the features of the jaw model, and at the same time constructs a tooth movement control data structure, arranges the teeth to the position and shape of the ideal dental arch through an automatic arrangement algorithm, and at the same time determines the target teeth After positioning, adjust the angle of the teeth according to the angle standard of the perfect dentition to meet the characteristic requirements of the ideal jaw. The invention can relatively automatically complete the alignment and adjustment of the ideal dentition of the digitized jaw, and improves the efficiency of formulating the individualized ideal position scheme of the patient.

Description

Technical field[0001]The invention belongs to the field of digital models, and in particular relates to a method for automatically generating a digital ideal dental model.[0002]technical background[0003]The generation of the ideal position of the digital dental jaw is based on the patient’s personalized digital dental model. Through the analysis and diagnosis of the case, the patient’s personalized ideal position plan is specified, and each tooth of the patient is rearranged and arranged In the process, the ideal jaw standard in orthodontics and the actual situation of the patient are taken into consideration, and the ideal position of the dental jaw is finally generated. Under the existing conditions, the ideal position of the tooth jaw is finally determined by artificially modifying the position of each tooth, which is not accurate enough and takes time and effort.Summary of the invention[0004]In order to solve the shortcomings of the prior art, the present invention discloses an ...
