Description

Technical Field

[0001] The utility model relates to the technical field of scanners, in particular to a denture 3D scanner. Background Art

[0002] In the medical field, dentures refer to restorations made after partial or complete tooth loss in the upper or lower jaws. Dentures not only restore the anatomical morphology and physiological function of the masticatory organ, but also maintain the health of the organ and prevent the occurrence of dental diseases over a long period of time. For example, they prevent the elongation of opposing teeth and the tilting of adjacent teeth. At the same time, they also allow patients to experience the beauty, comfort, and chewing experience of natural teeth. During the denture production process, the denture model needs to be 3D scanned to produce a 3D stereoscopic image in the computer imaging system for subsequent 3D printing. However, with current denture 3D scanners, the denture is mostly fixed during scanning, making the scanned data inaccurate and incomplete.
