[0002] In the case of missing posterior teeth at the free end, especially multiple missing distal free teeth, the preferred treatment option is implant restoration. In the current treatment, there is the problem of inaccurate occlusal scanning of implant restoration in the fully digital process. There is only gums in the edentulous area of ​​posterior teeth, and there is a lack of landmark points for image stitching and registration of intraoral scanners. Therefore, when performing buccal occlusal registration, the occlusal scanning information has a large deviation, which can easily cause deviation in the design of the occlusal surface of the upper restoration.
