From 1995 to 2005, a clinical trial was conducted on 442 Zimmer Biomet TMJ replacements in 288 cases. At landmark intervals, the patients were evaluated for pain, interference with eating, and maximal incisal opening. The study showed that there were no device-related mechanical failures and that there were statistically significant improvements in pain level, interference with eating, and incisal opening.

The study supports the conclusion that Zimmer Biomet stock TMJ replacements are a safe and effective option when temporomandibular joint reconstruction is needed.¹
