This study describes the clinical variables in 61 patients following total alloplastic temporomandibular joint reconstruction (TJR) in which the Biomet Microfixation Patient-Patient-Matched TMJ Implant was used. All patients were classified using the Wilkes classification. The visual analogue scale score for jaw pain intensity, the maximum inter-incisal opening (MK)), and the frequency of adverse events were recorded during follow-up; the mean follow-up was 14.2 8.6 months. Significant improvements were found in the MIO (P <0.0005), except at the 3-year follow-up. Additionally, a significant reduction in pain was observed both short and long term (P <0.0005). The incidence of adverse events was low (seven of the 81 alloplastic joints); two joints needed revision. TJR appears to be a relevant treatment option in patients with a broad range of temporomandibular joint disorders in whom none of the joint components are salvageable because of significant disease. Our patients gained an almost normal range of mouth opening and experienced a significant reduction in pain. Our results are promising, however TJR is associated with some side effects. TJR should be considered when less invasive procedures fail and a comprehensive presurgical work-up has been performed. Ongoing prospective studies are needed to consolidate the possible significant treatment outcomes.
