Abstract

The invention provides an elastic bionic artificial temporomandibular zygopophysis prosthesis and a preparation method thereof. The zygopophysis prosthesis comprises a bionic articular cartilage (1) and a mandibular branch metal prosthesis (2). The bionic articular cartilage is made of a high polymer material, and the mandibular branch metal prosthesis (2) is made of a metal material. The bionic articular cartilage (1) is arranged at the top end of the mandibular branch metal prosthesis (2), and the bionic articular cartilage (1) is fixedly connected with the mandibular branch metal prosthesis (2). The articular cartilage of the elastic bionic artificial temporomandibular zygopophysis is prepared from a combined material comprising ultra-high molecular weight polyethylene, and a certain connecting structure is designed to realize heterogeneous material integrated connection with a mandibular branch metal prosthesis, so that stable connection between artificial temporomandibular zygopophysis metal and an organic polymer surface structure is realized. The interior of the bionic articular cartilage is provided with an elastic structure, so that the elastic performance of a zygopophysis functional surface is improved.

Description

technical field [0001] The application belongs to the field of bionic prosthesis, in particular to an elastic bionic artificial temporomandibular joint prosthesis and a preparation method thereof. Background technique [0002] The temporomandibular joint is the only movable joint in the craniofacial region and one of the most complex joints in the human body. It has important physiological functions, including opening and closing of the mouth, swallowing, chewing, and language. Artificial temporomandibular joint prosthesis replacement has developed rapidly in recent years for those who cannot function normally due to temporomandibular joint defects caused by diseases such as tumors, trauma, joint ankylosis, rheumatoid arthritis and / or spontaneous resorption. New treatments. [0003] At present, most artificial temporomandibular joint prostheses at home and abroad mainly include two parts: the glenoid prosthesis made of ultra-high molecular weight polyethylene polymer and th...
