Problems solved by technology

[0003] In the prior art, artificial temporomandibular joints generally use finished artificial joints, which have a single joint shape, which is a flat titanium plate with screw holes and a semicircular imitation condyle structure at the upper end.
This structure does not conform to the anatomical shape of the natural condyle, and the functional movement of the condyle sliding and rotation cannot be realized; in addition, most condyle prostheses are mass-produced finished products, and the size design is difficult to meet the needs of each patient

Embodiment

[0035] see figure 1 , the present invention provides a kind of artificial temporomandibular joint based on selective laser melting technology, comprising: condyle 1, condyle neck 2 and titanium plate 4 provided with nail holes 5; It protrudes from the rear edge of the upper end of the condylar neck 2; the lower end of the condylar neck 2 is provided with a titanium plate 4.

[0036] The artificial temporomandibular joint based on selective laser melting technology also includes a coracoid process 3; similar to the human jaw structure, the coracoid process 3 protrudes from the front edge of the upper end of the condyle neck 2.

[0037] The artificial temporomandibular joint structure of the present invention is exactly the same as the mandibular structure of the human body. The condyle 1, the condyle neck 2 and the coracoid process 3 are structures of the human jaw. It should be noted that according to mechanical studies, the coracoid process 3 does not play a major role in b...

Abstract

The invention discloses an artificial temporal-mandibular joint based on selective laser melting technology and a manufacturing method thereof. The artificial temporal-mandibular joint comprises a condyle process, a condylar neck and a titanium plate formed with nail holes; the same as the structure of the mandible of human body, the condyle process is protruded at the rear edge of the upper end of the condylar neck; the titanium plate is mounted at the lower end of the condylar neck. According to the artificial temporal-mandibular joint based on selective laser melting technology and the manufacturing method thereof, the artificial temporal-mandibular joint is printed and formed in three dimensional mode through using selective laser melting technology, and the artificial temporal-mandibular joint is made according to the mandible shape of each patient, and accordingly the artificial temporal-mandibular joint is perfectly matched with the mandible structure of the patient.

Description

technical field [0001] The invention relates to the field of artificial joints, in particular to an artificial temporomandibular joint based on selective laser melting technology and a manufacturing method thereof. Background technique [0002] The temporomandibular joint (TMJ) is a left-right joint in the maxillofacial region with rotational and sliding movements. Tumors, trauma or fractures, congenital deformities, and osteochondritis can lead to temporomandibular joint space-occupying lesions or joint ankylosis, seriously affecting important functions such as mastication, swallowing, and language, while tumor resection, bone temporomandibular joint ankylosis surgery and severe Injury and other reasons can lead to loss of mandibular condyle. In order to restore the lower 1 / 3 height of the face and the function of the temporomandibular joint, temporomandibular joint reconstruction is required. Temporomandibular joint reconstruction is the use of autologous tissue transpla...
