Temporomandibular Total Joint Replacement Implant Devices: A Systematic Review of Their Outcomes.

Functional impairment affecting the quality of life results when a wide range of both muscular and joint pathologies affect the temporomandibular joint (TMJ). There are several total temporomandibular joint prosthesis systems available for total joint replacement (TJR). This systematic review provides an overview of the different TJR systems available and discusses their outcomes and efficiency. A systematic review on the outcomes of TJR was performed in October 2020. The five databases searched are PubMed, Europe PMC, Elsevier, SpringerLink, and British Journal of Oral and Maxillofacial Surgery. Outcome measurements were changes in maximal mouth opening (MMO), pain, diet, and functional limitation preoperatively and postoperatively. Seventeen follow-up studies were included in this systematic review, with 1,343 patients. All TMJ implant devices showed significant improvement after placement in all outcomes (pain, diet, MMO). All TJR prostheses showed great improvement comparing preoperative and postoperative outcomes. There was no significant difference between devices when comparing their outcomes.
