Abstract

The invention discloses an auxiliary device, an auxiliary device component and a method for obtaining three-dimensional graphics in the mouth. The auxiliary device is used to assist a three-dimensional scanner in the mouth to obtain three-dimensional graphics in the mouth, including: a connecting part, a characteristic part and a characteristic pattern. The connecting part can be installed on a fixed body; the characteristic part is connected to the connecting part, and has a sheet structure; the characteristic pattern is set on the characteristic part; wherein, when the connecting part is installed on the fixed body, the characteristic part is vertical or inclined relative to the alveolar ridge, so that the teeth The mucosa of the groove crest is exposed. In the auxiliary device of the embodiment of the present invention, the characteristic part is provided with a characteristic pattern, and the alveolar ridge mucosa is exposed. When scanning with a three-dimensional scanner in the mouth, the accurate spatial position relationship of multiple teeth and the alveolar can be obtained through one scan. The information of the ridge mucosa not only improves the scanning accuracy, but also improves the scanning efficiency.

Description

technical field [0001] The invention relates to the technical field of three-dimensional scanning, in particular to an auxiliary device, an auxiliary device component and an acquisition method of three-dimensional graphics in the mouth. Background technology [0002] At present, intraoral three-dimensional scanners are mostly used in single tooth restoration, three unit fixed bridge and upper restoration of single tooth implant, and their scanning accuracy can meet the clinical requirements. However, there are still deficiencies in the scanning accuracy of over three units of multi tooth fixed restoration, multi tooth implant restoration and mobile restoration. summary of the invention [0003] The invention provides an auxiliary device, an auxiliary device component and an acquisition method of three-dimensional graphics in the mouth, which can improve the scanning accuracy of multiple tooth positions. [0004] The auxiliary device of the embodiment of the invention is used to ...
