Abstract

The invention provides a temporomandibular joint (TMJ) and mandible joint prosthesis which at least comprises a TMJ fossa prosthesis, a mandible prosthesis and a joint head prosthesis, wherein the mandible prosthesis comprises a mandible ascending ramus part and a mandible extending part, the mandible ascending ramus part and the mandible extending part are connected to form an individualized simulation mandible ascending ramus and at least part of mandible body form; the tail end of the mandible ascending ramus part of the mandible prosthesis is fixedly connected with the articular head prosthesis; and the bent concave surface of the mandible prosthesis is used as the upper side, and a continuous or discontinuous porous structure area is arranged in the middle of the mandible prosthesis.The TMJ and mandible joint prosthesis can repair TMJ functions, mandible forms, dentition defects and the like of various TMJ-mandible joint defects individually at the same time to achieve joint reconstruction of TMJ-mandible-dentitions.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a temporomandibular joint and mandibular combined prosthesis. Background technique [0002] The temporomandibular joint (TMJ) is located in front of the tragus, adjacent to the base of the skull upward, and extends downward to the ramus of the mandible and the mandibular body. It is the only bilateral linkage joint in the human body. It has a fine structure and complex functions. When various lesions result in TMJ-mandibular joint defect or complete mandible, it will lead to severe dysfunction of mastication, swallowing, language and breathing, and even death. How to simultaneously restore the function of the temporomandibular joint, the shape of the mandible and the defect of the dentition has always been a difficult point in the field of oral and maxillofacial surgery. [0003] For temporomandibular joint-mandibular joint defects and total mandibular lesions, there are two main ...
