PIMENTA E SOUZA, Denis et al. Clinical evaluation of patients with total temporomandibular joint replacement. Rev Esp Cirug Oral y Maxilofac [online]. 2013, vol.35, n.3, pp.107-115. ISSN 2173-9161.

Introduction: The temporomandibular joint (TMJ) can be affected by injuries that alter its morphology and compromise its normal function, and in some cases leading to the need for surgery to resect it and rebuild it. The reconstruction of the TMJ bone articular defects has been a challenge for the maxillofacial surgeon. It can be achieved by using alloplastic materials. Among these, we highlight the total temporomandibular joint prosthesis, developed until achieving its current form and composition, and which has led to the establishment of clear protocols for its use. Among these, we highlight the W.Lorenz™ prosthesis with a high technology and specific details that lead to an increased clinical and functional improvement. Objective: To study the important clinical and functional aspects observed in surgically treated patients. Materials and Methods: This study evaluated 15 patients between 24 to 44 years, who underwent TMJ replacement surgery with 23 TMJ implants, 8 bilateral and 7 unilateral, between the years 2000 to 2008. All surgeries were performed by the same surgeon. Results: A large increase in functional improvement was observed, particularly in the cases of TMJ ankylosis. Conclusions: Many more studies and monitoring should be conducted to establish, especially in the long term, that these prostheses offer the stomatognathic system an effective and durable physiology.
