“…These high stresses may be explained by decreases in superior contact force and increases in posterior contact force at the prosthetic TMJ. Increased contact stress at the prosthetic TMJ increases potential for component wear and material failure or TMJ dislocation [6,38]. Our findings indicate that correctly align ing the condylar component in the anterior-posterior direction and ensuring that the contacting surfaces are congruent intraoperatively may be a critical factor in implant performance and longevity.…”

One of the most widely reported complications associated with temporomandibular joint (TMJ) prosthetic total joint replacement (TJR) surgery is condylar component screw loosening and instability. The objective of this study was to develop a musculoskeletal model of the human jaw to assess the influence of prosthetic condylar component orientation and screw placement on condylar component loading during mastication. A three-dimensional model of the jaw comprising the maxilla, mandible, masticatory muscles, articular cartilage, and articular disks was developed. Simulations of mastication and a maximum force bite were performed for the natural TMJ and the TMJ after prosthetic TJR surgery, including cases for mastication where the condylar component was rotated anteriorly by 0 deg, 5 deg, 10 deg, and 15 deg. Three clinically significant screw configurations were investigated: a complete, posterior, and minimal-posterior screw (MPS) configuration. Increases in condylar anterior rotation led to an increase in prosthetic condylar component contact stresses and substantial increases in condylar component screw stresses. The use of more screws in condylar fixation reduced screw stress magnitudes and maximum condylar component stresses. Screws placed superiorly experienced higher stresses than those of all other condylar fixation screws. The results of the present study have important implication for the way in which prosthetic components are placed during TMJ prosthetic TJR surgery.

“…Kent introduced the total TMJ prosthesis. Between 1981 and 1990 several thousand patients were implanted with what then became known as the Vitek-Kent prosthesis [17]. In the early 1980s, Sonnenburg developed a total TMJ replacement in Eastern Germany.…”

Introduction Temporomandibular joint (TMJ) ankylosis involves the fusion of the mandibular condyle to the glenoid fossa, the skull base. The dilemma with regards to treatment planning whether distraction is done before gap arthroplasty or as a simultaneous procedure or after gap arthroplasty is still a controversy. In an attempt to carry out both the procedures simultaneously there is loss of vector control of the distal segment and the risk of pseudoarthrosis at the osteotomy site. This combined problem could be overcome by the use of total alloplastic joint prosthesis which offers a firm posterior stop for the proximal segment and negates aggressive physiotherapy. Material and methods The reference literatures were retrieved from Pub Med and Science Direct database. Three case reports of bilateral recurrent TMJ ankylosis successfully treated with custom made total TMJ by the authors are illustrated. Conclusion The purpose of this article is to review the world literature on various alloplastic joints available for TMJ reconstruction and to introduce our indigenous total joint prosthesis in the management of recurrent ankylosis.

“…Various flaps and materials have been used to replace the missing or destroyed disc but none have been particularly successful. 4,5 The use of alloplastic materials for TMJ reconstruction fell into disuse in the 1970s as a result of problems with the Kent ⁄ Vitek prosthesis 6,7 which caused many foreign body reactions to the proplast and teflon used in the manufacture of the glenoid fossa component of the prosthesis.…”

This paper is a preliminary paper which presents the early findings of an ongoing prospective trial on the use of the TMJ Concepts and Biomet Lorenz total joint replacement systems for the reconstruction of the temporomandibular joint (TMJ).Total alloplastic replacement of the TMJ has become a viable option for many people who suffer from TMJ disease where surgical reconstruction is indicated. Degenerative joint diseases such as osteoarthritis, rheumatoid arthritis, psoriatic arthritis, TMJ ankylosis, malunited condylar fractures and tumours can be successfully treated using this technique.There are a number of TMJ prostheses available. Two of the joint replacement products, which have been found to be most reliable and have FDA approval in the United States, are the TMJ Concepts system and the Biomet Lorenz system, and for this reason they are being investigated in this study.This study presents the findings of seven patients with a total of 12 joint replacements using either the TMJ Concepts system or the Biomet Lorenz joint system. Two patients (3 joints) had the TMJ Concepts system and five patients (9 joints) had the Biomet Lorenz system.Although still early, the results were generally pleasing, with the longest replacement having been in position for three years and the most recent six months. The average postoperative mouth opening was 29.7 mm (range 25-35 mm) with an average pain score of 1.7 (range 0-3, minimum score of 0 and maximum 10). Complications were minimal and related to sensory disturbance to the lip in one patient and joint dislocation in two patients.
