Abstract: The disclosure provides a scanner head assembly, including: a scanner host and a scanner head. The scanner host includes a base section and an insertion head section forming an integral structure with the base section, and the insertion head section is provided with a switch. The scanner head includes a scanner head body. The scanner head body has a cylinder. The insertion head section is nested in the cylinder of the scanner head, and the switch is fitted with the scanner head to realize control of the scanner host. The technical solution of the disclosure effectively solves the problem that it is not convenient for the scanner head assembly in the art known to inventors to switch between scanning states when using different scanner heads.

Abstract: The present disclosure provides a denture bearing mechanism, a denture three-dimensional scanner and a control method thereof. The denture bearing mechanism includes a fixed seat, a bearing table and a driving assembly, where the fixed seat is detachably mounted on a storage table of the denture three-dimensional scanner; the bearing table is arranged on the fixed seat and connected to the driving assemblies; the driving assemblies are used for driving the bearing table to move relative to the fixed seat; and at least two scanning stations for placement of denture models are provided on the bearing table, so that the scanning stations can be mutually switched over in a motion state.
