The processing of the new TMJ prosthesis, including the pre-processing for the craniomaxillofacial model, the design for the prosthesis, and the manufacture for the prosthesis. The main innovative points of the prosthesis are the customized fossa component with single UHMWP and the Machine tape mechanism for the connection between the condylar head (Co–Cr–Mo alloy) and mandibular handle components (Ti6Al4 V alloy)
