Total alloplastic temporomandibular joint replacement: the Czech-Slovak initial experience

Prospective study of five-year outcomes and postoperative complications after total temporomandibular joint replacement with two stock prosthetic systems

“…Compared with other operations such as costochondral and sternoclavicular grafts, TMJ prostheses reduce the duration of the operation and the time spent in hospital, and provide immediate function after the operation without morbidity from a donor site. [6][7][8][9][10] As the joint replacement is a complicated interactive biomechanical system, long-term studies remain the ultimate test of safety and efficacy. 4,17,18 This was our main reason to evaluate and compare outcomes and complications associated with stock prostheses.…”

Assessment of clinical parameters and patient satisfaction submitted to rehabilitation with total joint prostheses of temporomandibular joint

“…The most common diseases were hypertension and arthritis, being related to the major diseases that cause joint disorders, which are inflammatory or local resorptive pathologies, autoimmune diseases [4,12,14,20], in addition to fibrous or bony ankylosis which are among the main indications for TMJ prostheses [3].…”

“…Another plus was that in this study, no trans-surgical injury or postoperative complications took place. Some authors refer in their studies that the most common complications are neuropraxis mainly caused by retraction maneuvers and use of electrocautery, and intraoperative bleeding due to injury of maxillary artery branches and plexus pterigoideo 4 in addition to infections, malocclusion, hematoma, metallic component dislocations, prosthesis attachment loss, and even locoregional bone formation are likely to happen [4,15], suggesting this procedure requires some experience of the surgical team; however, when the procedure is performed with well-employed surgical technique, along with adequate postoperative follow-up, clinical success is expected as with our study. In this study postoperative comfort was not directly related to the intraoperative aspect of the TMJ, to the number of prosthesis used, to the masticatory satisfaction level after surgery, to the improvement in social life or to the differences between the pre-and postoperative for any of the measures studied as well as the studies [1, 8,15,17,34].…”

“…Recent studies demonstrate that alloplastic devices have advantages when compared to autografts for the rehabilitation of patients, especially when considering the need of donor sites, morbidity and surgical time, and longer lasting results [1, 4,8,17,21,25].…”

Total Joint Replacement: Biomaterials for Application in the Temporomandibular Joint

“…More recent studies have shown that the submicron wear particles (0.1-1 μm) are more reactive than larger particles (>1 μm) and that the release of osteolytic cytokines is dependent on the volumetric concentration of the submicron wear particles. This has led to the study of the volume distribution of the wear particles in different size ranges to analyze their osteolytic potential [5].…”
