Clinical guidelines for total temporomandibular joint replacement

Tetsuya Yoda et al. Jpn Dent Sci Rev. 2020 Nov.

Abstract

Total joint replacement (TJR) of the temporomandibular joint (TMJ) is a promising surgical procedure and device for treating end-stage diseases of the TMJ. For the functional and aesthetic reconstruction of the oral and maxillofacial head and neck region, TMJ TJR significantly helps maintain the patient's quality of life in terms of a better diet, mastication, speech and social interaction. TMJ TJR was approved by regulatory authorities in 2019 in Japan, thus enabling the clinical application of the TJR system. However, the surgery demands particularly difficult and high-risk procedures, necessitating the prudent selection of indicated patients. The joint committee of the Japanese Society of Oral and Maxillofacial Surgeons and Japanese Society for Temporomandibular Joint is working together to develop an appropriate clinical guideline for TMJ TJR.

Keywords: Clinical guideline; Temporomandibular joint; Total joint replacement.

The mandibular component of the Biomet Microfixation, Total Temporomandibular Joint (TMJ) Replacement System. The surface of the mandibular component in contact with the mandible is made of titanium alloy (Ti–6AL–4V) powder plasma sprayed with a cobalt-chromium-molybdenum (Co–Cr–Mo) alloy.

Installation of the Biomet Microfixation, Total Temporomandibular Joint (TMJ) Replacement System. The system consists of a mandibular implant (mandibular branch component/artificial mandibular condylar process) and a fossa implant (glenoid component/artificial glenoid fossa), which are designed specifically for both right- and left-side TMJ.
