Abstract

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.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a bionic artificial temporomandibular joint replacement prosthesis. Background technique [0002] Temporomandibular joint replacement is an effective means of treating advanced osteoarthropathy, joint ankylosis, tumor, idiopathic resorption and other diseases. Among them, the artificial temporomandibular joint prosthesis has the advantages of being stable and non-absorbing, and does not need to open up a second operation area, thereby reducing surgical trauma, and is widely used abroad. However, none of the current prosthetic designs can achieve muscle bioattachment, thus failing to achieve the physiological range of motion of the joint, while increasing the burden on the healthy side joint. Contents of the invention [0003] The technical problem solved by the invention is to overcome the defects of the prior art and provide a bionic artificial temporomandibular joint replac...
