Temporomandibular joint total replacement using the Zimmer Biomet Microfixation patient-matched prosthesis results in reduced pain and improved function.

Objective: The aim of this study was to evaluate pain and maximum interincisal opening (MIO) in patients treated with the Zimmer Biomet Microfixation patient-matched alloplastic temporomandibular joint (TMJ) prosthesis.

Study Design: We performed a retrospective cohort study of patients who had undergone bilateral or unilateral TMJ total joint replacement (TJR). The primary outcome variables were pain and MIO, which were measured at various time points between 12 and greater than 60 months.
