The invention relates to the technical field of medical treatment and in particular relates to a bionic artificial temporal-mandibular joint replacement prosthesis. According to the bionic artificialtemporal-mandibular joint replacement prosthesis, in-growth and attachment of lateral pterygoid muscles can be realized, so that the motion range of the joint prosthesis is widened, and the defects that the pure mechanical joint has limited motion and burdens on lateral healthy joints are increased are overcome. Due to hydroxyapatite coating on the contact surface of socket prosthesis and bones and the porous titanium structure of the contact surface of mandibular prosthesis and bones, the bonding capacity of the prosthesis and bones is increased, and aseptic necrosis of bones caused by micromotion of the prosthesis is avoided, so that the using effect of the prosthesis is improved and the service life of the prosthesis is prolonged. 本发明涉及医疗技术领域，具体为种仿生人工颞下颌关节置换假体，该仿生人工颞下颌关节置换假体，可以实现翼外肌的长入与附着，从而增加人工关节的运动范围，避免了单纯机械关
