Embodiment Construction

[0031] The following is attached Figure 1-5 The application is described in further detail.

[0032] The embodiment of the present application discloses a temporomandibular joint prosthesis.

[0033] Such as figure 1 and figure 2 As shown, the temporomandibular joint prosthesis includes a mandibular prosthesis 1, a mandibular fixation plate 2 for connecting the mandible, a condyle prosthesis 3 connected to the mandibular prosthesis 1, a glenoid prosthesis 4 and a Connect the glenoid fixation plate 5 of the maxilla.

[0034] Such as figure 2 and image 3 As shown, the mandibular prosthesis 1 is a bionic structure of the human mandible, and the surface of the mandibular prosthesis 1 is formed with meshes so that the nearby muscles can be better attached to the mandibular prosthesis 1. At the same time, the mandibular prosthesis 1 The interior is a diamond-like unit cell structure as an internal support. The mandibular fixation plate 2 is integrally formed on the outer ...

Abstract

The present invention relates to the field of implant prostheses and particularly to a temporomandibular joint prosthesis. The temporomandibular joint prosthesis comprises a mandible prosthesis, a mandible fixing plate, a glenoid fossa prosthesis made of ultra-high molecular weight polyethylene/ceramic, a glenoid fossa fixing plate and a condyle process prosthesis prepared from cobalt-chromium-molybdenum alloy by mechanical processing/ceramic, a positioning boss is formed at one end, matched with the condyle process prosthesis, of the mandible prosthesis, and a positioning groove matched withthe positioning boss is formed in the condyle process prosthesis. A condyle process on the mandible prosthesis is designed into the separated single condyle process prosthesis, and the condyle processprosthesis is made of the cobalt-chromium-molybdenum alloy or ceramic and matched with the glenoid fossa prosthesis made of the high polymer polyethylene material or ceramic to form a structure of amovable joint part. Therefore, the mandible joint and the mandible fixing plate can be subjected to 3D printing by a titanium alloy material to adapt to a unique face shape of each patient, and meanwhile, a problem of osteolysis caused by long-term use is also solved.

Description

technical field [0001] The present application relates to the field of implanted prosthesis, in particular to a temporomandibular joint prosthesis. Background technique [0002] The temporomandibular joint is often partially or completely lost its anatomical structure due to trauma, tumor, inflammation, ankylosis or congenital diseases, so that its function is partially or completely lost. The ideal method is to reconstruct a new joint with the same shape, tissue composition and function as the original temporomandibular joint, and restore the function of the joint, but this is not possible at present, and artificial joints are one of the options. [0003] Temporomandibular joint prosthesis In order to adapt to each person's unique human body structure, and in consideration of convenient processing, sufficient strength, and no human body rejection, our company's original temporomandibular joint prosthesis uses high molecular weight polyethylene and titanium alloy 3D print f...
