Embodiment 1

[0015] Application of Rib - Rib Carnes in Reconstruction of Tempcmonium Jandibular Junction.

[0016] The rib selects a neutral bone cover with a thin layer to wind the bone bone inset.

[0017] The rib cartilage is selected from 0% calcification of ribs.

[0018] The rib cartilage is selected with a calcium-free rib cartilage.

[0019] The rib-rib cartilage selection transverse surface is an elliptical form.

[0020] The rib-rib cartilage has a bending degree of 10 °.

[0021] Use process:

[0022] 20 patients were subjected to surgery in hemp. Open the temporomandibular joint through the ear front incision.

[0023] The overlapping portion of the lifting bone sketch can be reached to obtain a good bone connection interface to place the rib into the corresponding position. For the stem of temporomandibular joints, both sides should also be removed. If the joint disk is complete, it can be retained. Otherwise, a temporal fascia flap will be applied to the joint disc. All patients ...

Abstract

The invention discloses an application of a rib-costal cartilage in reconstruction of a temporomandibular joint. And the ribs are densely arranged cancellous bones which are provided with thin-layer compact bones and surround bone trabecula. The costal cartilages are selected from costal cartilages with the calcification degree of 0-25%. The costal cartilage is selected from non-calcification type costal cartilage. The cross section of the rib-costal cartilage selection is in an oval shape. The bending degree of the rib-costal cartilage ranges from 0 degree to 10 degrees. The rib and the costal cartilage have the advantages of being good in biocompatibility, free of rejection reaction, easy to survive and the like, and the temporal-mandibular joint replacement technology using the rib and the costal cartilage has the advantages of being low in complication occurrence rate, good in shape fitness and wide in application prospect.

Description

Technical field [0001] The present invention relates to the field of biotechnology, and in particular the application of rib-rib cartilage in reconstruction of temporomandibular joint. Background technique [0002] Temporomandibular Joint, TMJ) disease is a common disease, multiple disease, its incidence is more than 28% abroad, is one of the most common diseases of oral and maxillofacial surgery, mainly including TMJ structural disorders, osteoarth Diseases, infectious arthritis, joint developmental diseases, and their respective maxillofacial deformities, joint fractures, strong, dislocation, tumors, etc. The clinical manifestations are mainly spontaneous pain in the joint zone, limited to the joint murmour, bite disorder, the abnormalities and dysfunction of mandible movement, and severely affect the patient's chewing, language and other functions, and even endanger the life of the patient. For medium, advanced TMJ bone joint disease, severe inflammatory or idiopathic condylar...
