“…For these patients alloplastic total joint replacement may be the only treatment option left (van Loon et al, 2002). Different TMJ prostheses have been described over the years, but all have their limitations (Driemel et al, 2009;Guarda-Nardini et al, 2008b). Owing to the prosthesis design, translatory movements of the condyle are often absent or severely restricted (Mercuri and Anspach, 2003).…”

“…One of the major points of questioning is about the longevity of these prostheses. Experienced authors expectation is 20 years of time use [14]. Relationship between time use of the prosthesis and laterality (Unilateral Or Bilateral) was not found, but it can be observed that all patients evaluated and undergoing treatment are in full use and without reinterventions needed for postoperative complications.…”

“…In the other patients immediate reconstruction was performed with TMJ prosthesis, divergent from the literature which suggests that patients who are candidate for condylar prosthesis installation surgery are those with multiple previous interventions in the region [13,14,20], these being the ones who have the worst results and lower rate of success [13,14] .…”

The aim of this study was to investigate the clinical efficacy of temporomandibular alloplastic prosthesis for full reconstruction of the temporomandibular joint. The total sample was 44 patients, including 17 men and 27 women. Clinical parameters such as deviation and limitation of mouth opening and facial asymmetry, and subjective criteria such as headache, difficulty chewing, local pain and the degree of patient satisfaction postoperatively were used. The mean of the follow up was approximately 5 years. It was observed that the mouth opening postoperatively was higher than that of preoperative showing an average increase of 14.6 ± 8.04 mm. Similarly, the measure of laterality and protrusion also increased significantly postoperatively. Reports of snap, crackle, headache, facial asymmetry and mainly local pain significantly decreased (Fisher exact test, p <0.05) after surgery. It was observed that 33 (75%) subjects had improvement in both chewing and socializing, and 37 (84.1%) showed improvement in chewing and 40 (90.9%) showed improvement in social life. The results of this research showed that studied the prosthesis is an effective and predictable option for full reconstruction of the TMJ.

“…Total replacement of the temporomandibular joint (TMJ) involves the removal of the "non functional" joint and placing an artificial one [1]. TMJ reconstruction was developed to improve the mandibular function and reduce disability [2].…”

Numerical and Experimental Models of the Mandible

This study aimed to validate a numerical model of an intact mandible for further development of a new TMJ implant. Numerical and experimental models of the biomechanics of the mandible were elaborated to characterize the human temporomandibular joint and to approach the development of a condyle implant. The model of the mandible was obtained through the use of a polymeric replica of a human cadaveric mandible and through 3D geometry acquisition. The three-dimensional finite element model was generated as a tetrahedral finite element mesh. The level of mesh refinement was established via a convergence test and a model with more than 50,000 degrees of freedom was required to obtain analysis accuracy. The functional loading cases included muscle loading in four different load boundary conditions. The same boundary conditions were applied to the experimental model. The strains were measured with an experimental procedure using electric resistance strain gauges applied on the external surface of the mandible. The mechanical response is shown and discussed in terms of strains, principal numerical and measured strains. This study proved that FE models of the mandible can reproduce experimental strains within an overall agreement of 10%. The FE models correctly reproduced bone strains under different load configurations and therefore can be used for the design of a novel TMJ implant considering other load configurations and bone mechanical properties.
