Studies of TMJ concepts

Citation	Study design	Population	Results
Wolford et al. [13]	Retrospective	38 patients 69 joints	TMJ concepts/techmedica total joint prosthesis works well long-term.
Murdoch et al. [14]	Retrospective	42 patients 63 joints	It appears that the TMJ concepts patient-fitted system offers improved long-term results
Sidebottom and Gruber [15]	Prospective	74 patients 103 joints	This study provides further evidence for the efficacy and safety of total alloplastic TMJ reconstruction.
Mercuri et al. [16]	Retrospective	58 patients 97 joints	The CAD/CAM patient fitted total TMJ reconstruction systemhas proved to be a safe and effective long-term management modality in the patient population surveyed in this study.
Mercuri et al. [17]	Retrospective	61 patients 102 joints	The patient-fitted total TMJ reconstruction system continues to be a safe, effective, and reliable long-term management modality for the specific patient population surveyed in this study.
Jones [18]	Retrospective	2 patients 3 joints (Biomet 5 patients)	The alloplastic joint replacements were pleasing but long term review is required.
