Description

Technical Field

[0002] According to the published patent with patent announcement number CN219538536U, a 3D scanning device for denture production includes a base and a scanning assembly. The top of the base is fixedly connected with a dental mold holder and a support seat respectively. The dental mold holder is located on the inner side of the support seat and is driven to move on the dental mold holder by providing a protective cover, so that the dental mold can be covered by the protective cover during 3D scanning, thereby preventing the dental mold from being accidentally touched and offset during the scanning process to affect the modeling quality. However, there are still the following shortcomings, such as:

[0003] The above scanning device cannot fix the dental model, so that the dental model is prone to shaking during scanning, which may cause the dental model to deviate from the predetermined position and affect the data generated by the scanner when scanning the dental model.
