Title:
FLAT MUCOUS MEMBRANE SCANNING AND OPTICAL SHAPING METHOD AND SYSTEM BASED ON DEGREE-OF-MOTION MONITORING
Document Type and Number:
WIPO Patent Application WO/2023/160311
Kind Code:
A1
Abstract:
A flat mucous membrane scanning and optical shaping method and system based on degree-of-motion monitoring. The flat mucous membrane scanning and optical shaping method based on degree-of-motion monitoring comprises: identifying the microscopic morphologies of flat gums and mucous membrane surfaces by using a high-resolution camera, combining the microscopic morphologies into a splicing feature as a feature mark for scanned image splicing, and on the basis of the feature mark, performing static scanning to obtain a mucous membrane image; and on the basis of static scanning, enabling a patient to simulate physiological movement such as chewing, simultaneously performing mucous membrane dynamic scanning, and performing real-time monitoring on the basis of the degree of motion of mucous membranes and AI to obtain the three-dimensional scanning data of a muscle static region, thereby achieving optical shaping. Dentition and a small amount of gums around the dentition can be scanned, the flat gums and oral mucous membranes of a large-area edentulous region can also be accurately scanned, and the intraoral three-dimensional scanning efficiency and accuracy of the flat gums and the mucous membrane regions are greatly improved.
