Description

Technical Field

[0001] The utility model relates to the technical field of denture processing, in particular to a denture processing and fixing device. Background Art

[0002] Dentures are what people often call "false teeth", just like "false legs" and "false limbs" are called "artificial limbs". In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth. Dentures are divided into removable and fixed types.

[0003] Dentures are widely used and in high demand. Cutting is an essential process in their production. However, during cutting, the denture model was previously manually held, which was highly dangerous. Later, the denture model was clamped using a fixture, which generally lacked stability. Furthermore, existing fixtures cannot rotate during use, making it inconvenient to process the denture model. Separate processing steps can easily lead to dimensional deviations, affecting product quality. Therefore, we propose a denture processing fixture to address these issues. Utility Model Content
