Problems solved by technology

[0002] 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

Abstract

The invention discloses a porous artificial temporal-mandibular joint structure and a making method.The porous artificial temporal-mandibular joint structure comprises a coracoid, a condyle process, a condyle process neck and titanium plates provided with nail holes.The coracoid protrudes from the front edge of the upper end of the condyle process neck, the condyle process protrudes from the back edge of the upper end of the condyle process neck, and the titanium plates are arranged at the lower end of the condyle process neck.The artificial temporal-mandibular joint is a porous component and is composed of a plurality of mesh units, the mesh units are in hollowed truncated octahedron shapes, the thickness of frames of the mesh units ranges from 200 microns to 300 microns, the apertures of the mesh units range from 500 microns to 1,250 microns, and the porosity of a porous body is 75%-80%.The strength of the porous artificial temporal-mandibular joint structure is similar to that of primary skeleton of a patient, the tenacity of the porous artificial temporal-mandibular joint structure is similar to that of the primary skeleton of the patient, stress concentration generated after implantation can be avoided, and the porous structure can assist peripheral tissues in combination with the artificial temporal-mandibular joint.

Description

technical field [0001] The invention relates to the technical field of artificial bones, in particular to a porous artificial temporomandibular joint structure and a manufacturing method. Background technique [0002] 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 cannot realize the functional movement of the condyle sliding and rotation; in addition, most condylar prostheses are mass-produced finished products, and the size design is difficult to meet the needs of each patient. [0003] Even though the artificial temporomandibular joint prepared by metal 3D printing technology can meet the patient's individual structural needs, its overall density is still quite different from the patient's original ...
