Direct three-dimensional scanning method and system for physiological motion boundary of oral soft tissue

Abstract

The invention belongs to the technical field of oral scanning, and discloses a direct three-dimensional scanning method and system for a physiological motion boundary of oral soft tissue. The direct three-dimensional scanning system for the physiological motion boundary of the oral soft tissue comprises an oral image acquisition module, an oral image processing module, an oral image segmentation module, a central control module, a non-motion area acquisition module, a direct three-dimensional scanning module, a three-dimensional scanning data acquisition module, a data storage module, a terminal module and a display module. The scanning system provided by the invention is high in scanning speed, high in precision and simple to operate; an active contour method is used for semi-automatically carrying out labeling segmentation on an oral medical image serving as a training set, and the semi-automatic method improves the accuracy and timeliness of labeling segmentation; and a confrontation generation network is used for automatically generating a segmentation result of the oral medical image, so that the complete and effective expression of the healthy oral physiological structure isbalanced in key indexes such as segmentation precision, efficiency, stability and robustness.

Description

technical field [0001] The invention belongs to the technical field of intraoral scanning, and in particular relates to a direct three-dimensional scanning method and system for the physiological movement boundary of oral soft tissue. Background technique [0002] Typically, dental treatment is performed by an impression procedure in which a plaster model of a patient's teeth is taken in a dental office or similar. However, this impression process may be accompanied by various problems such as consumption of impression material, cross-contamination, breakage of the assembled model, etc. Therefore, the two-dimensional pattern of teeth is formed by radiating radiation, which has the disadvantages of exposing the patient to a large amount of radiation and poor precision. Then, three-dimensional dental scanners were developed and widely used. However, although the existing intraoral scanning methods can scan the soft tissues in the oral cavity, the main problems are: first, th...

Problems solved by technology

However, although the existing intraoral scanning methods can scan the soft tissues in the oral cavity, the main problems are: first, the three-dimensional intraoral scanner cannot obtain the functional boundary of the soft tissues; The impression is inaccurate; the third is that the efficiency and success rate of making an impression of the functional boundary of the oral soft tissue is low

[0004] (1) Existing intraoral 3D scanners cannot obtain functional boundaries of soft tissues

[0005] (2) The existing intraoral scanning method is inaccurate in making an impression of the functional boundary of the oral soft tissue

[0006] (3) The current efficiency and success rate of making oral soft tissue functional boundary impressions is low
