Purpose:
The aim of the present study was to assess pain, function, diet, and quality of life (QOL) in subjects undergoing alloplastic temporomandibular joint (TMJ) reconstruction.
Materials And Methods:
A total of 72 subjects were sent a questionnaire an average of 4 years after undergoing either unilateral or bilateral total joint replacement with a custom TMJ Concepts or stock Biomet total joint replacement device. The changes in pain, function, diet, and quality of life were assessed.
Results:
Of the 72 subjects, 52 returned the questionnaire. Pain, function, diet, and QOL were all significantly improved at a mean follow-up of 46.3 months. The complications reported included an altered facial sensation and facial weakness. No implant failures were reported.
Conclusions:
The placement of an alloplastic TMJ total joint replacement can provide benefits for patients in the areas of pain, function, diet, and QOL. Additional research is required in this area.
