[0033] A denture impression is an impression of the upper and lower edentulous alveolar ridges and the surrounding soft and hard tissues obtained using a plastic impression material. This impression needs to accurately reflect the oral anatomical morphology and the physiological function activities of the surrounding tissues, so that the denture base can be highly fitted with the oral mucosa and has an edge sealing effect, thereby ensuring that the complete denture has a good retention effect. Therefore, the production process of the denture impression is very crucial, and its quality and accuracy directly affect the subsequent production and fitting effect of the denture. Currently, during the process of placing the denture impression on the scanning table for scanning, since the traditional scanning table can only place or clamp a single-sided denture impression, when a double-sided impression needs to be scanned, the user needs to first scan one side of the impression, and then, after reinstallation operations, scan the other side of the impression. This installation and scanning mode has poor compatibility and low scanning efficiency, thus affecting the scanning process and making the scanning process rather cumbersome.

[0034] Therefore, there is an urgent need to develop a more adaptable fixing fixture for denture impressions, which can adaptively install denture impressions with different single-sided and double-sided structures, thereby simplifying the operation during the scanning of denture impressions, saving scanning time, and improving the user experience.

Optionally, the magnetic attraction block 114 in this embodiment is a magnet. Further, the fixing fixture 100 further includes a positioning pin shaft 115. A first fitting hole 12a is provided on the surface of the cushion block 111 facing away from the installation groove. The positioning pin shaft 115 is embedded and fixed in the first fitting hole 12a. It can be understood that the first fitting hole 12a is a pin limiting hole for limiting the positioning pin shaft 115. And the number of the first fitting holes 12a is set to be multiple, and the number of the positioning pin shafts 115 is equal to the number of the first fitting holes 12a.
