The clasp body, also known as the clasp shoulder, is a hard part that connects the clasp arm, support bracket, and small connector body. It surrounds the non inverted concave area of the base tooth and passes through the buccal lingual axis angle from the adjacent surface, which can prevent gingival and lateral movement of the denture, stabilize and support the denture, and support the clasp arm. Therefore, it is required that the Dalian CNC machining clasp body has high strength, is not easy to deform, is located in the non inverted concave area, and does not affect bite.
