Embodiment

[0017] like figure 1 As shown, a kind of artificial temporomandibular joint based on three-dimensional printing of the best embodiment of the present invention includes temporomandibular articular process 1, temporal bone articular surface 6, condylar process 4 and condylar process fixation handle 5, and said temporomandibular articular surface 1. The temporal bone zygomatic process fixation piece forms the glenoid fossa, the top of the condyle 4 is the articular head 3, which is movably connected through the glenoid fossa 2, and the tail end of the condyle 4 is also provided with the condyle The condylar process fixation handle 5, the condyle process 4, the condyle process fixation handle 5, and the glenoid fossa are produced using three-dimensional printing technology. The material of the articular fossa will be three-dimensionally printed using polyetheretherketone and other materials with high wear resistance and good biocompatibility, which can reduce the wear and tear of...

Abstract

The invention relates to an artificial temporomandibular joint based on three-dimensional printing. The artificial temporomandibular joint comprises a temporal bone joint surface, a temporal bone zygomatic process fixing plate, a processus condyloideus and a processus condyloideus fixing handle. The temporal bone joint surface and the temporal bone zygomatic process fixing plate form an articular fossa. The processus condyloideus is a joint. The processus condyloideus performs activities such as opening and closing through the articular fossa. The tail end of the processus condyloideus is also provided with a processus condyloideus fixing handle. The processus condyloideus and the processus condyloideus fixing handle are manufactured by means of three-dimensional printing technology. The articular fossa is made of high-wearing-resistance and high-biological-compatibility material such as poly(ether-ether-ketone). The material can reduce joint wearing. According to the artificial temporomandibular joint, individual design is performed according to patient anatomical features such as radian of the temporal bone joint surface and the temporal bone zygomatic process, the width, the angle and the appearance of a mandible ramus, so that the temporal bone zygomatic process fixing plate and the processus condyloideus fixing handle can well abut against the temporal bone joint surface, the temporal bone zygomatic process and the mandible ramus, thereby manufacturing the artificial temporomandibular joint which accords with the anatomical features of Chinese people.

Description

technical field [0001] The invention relates to the technical field of biomedical equipment, in particular to an artificial temporomandibular joint based on three-dimensional printing. Background technique [0002] The temporomandibular joint is one of the most important joints in the human body. It undertakes multiple important functions such as chewing, facial movement, and swallowing. Oral and maxillofacial tumors, trauma, and congenital and acquired deformities often cause destruction of the temporomandibular joint, requiring reconstructive surgery for the temporomandibular joint. Currently, customized TMJ Concepts / Techmedic and Biomet / Lorenz standardized prostheses are commonly used internationally. my country's SFDA approved the clinical application of the latter temporomandibular joint prosthesis. The main disadvantage of this joint prosthesis is that it is designed and manufactured according to the characteristics of the Caucasian temporomandibular joint, and there...
