“…Estes tipos de próteses possuem um côndilo e um ramo em liga de CoCrMo (ASTM tipo F799 ou F1537) e apresentam na sua superfície do corpo ou ramo um revestimento em titânio para promover o processo de osseointegração (Giannakopoulos et al, 2012;Kanatsios et al, 2018;Zou et al, 2018). O componente fossa consiste numa superfície de um polietileno de ultra-densidade molecular (UHMWPE), sem suporte metálico (Baena et al, 2015;Elledge et al, 2019;Kanatsios et al, 2018;Mamidi et al, 2019). Ambos os componentes são fixados por meio de parafusos autorroscantes de 2.0mm para a fossa e 2.7mm para o componente mandibular (Baena et al, 2015;Ferreira et al, 2014;Giannakopoulos et al, 2012;Kanatsios et al, 2018).…”

“…No entanto se o doente não tiver historial cirúrgico significativo e possuir anatomia normal e sem variações, tornase desnecessário o uso de prótese personalizada. As principais desvantagens das próteses personalizadas (i.e., TMJ Concepts) são o custo, o tempo necessário para a fabricação do dispositivo, e a dificuldade de autorização governamental em alguns países (Abramowicz et al, 2012b;Brown et al, 2020;Gerbino et al, 2017;Rhee et al, 2019;Siegmund et al, 2019) Como os componentes personalizados do dispositivo se ajustam tão bem ao contexto anatómico, há uma melhoria na recuperação da função imediata mandibular, importante para o sucesso a longo prazo e que deve começar logo após a colocação do implante, por meio de fisioterapia ativa (Elledge et al, 2019(Elledge et al, , 2018. Com os sistemas CAD/CAM e tecnologia de impressão tridimensional, a personalização oferece benefícios claros sobre a substituição autógena da ATM o que diminui assim a morbidade do local doador e o tempo cirúrgico (Elledge et al, 2018;Mamidi et al, 2019;Mercuri, 2012).…”

“…TMJ prosthesis is one of the most important therapeutic methods, including TMJ Concepts/Techmedica personalized prosthesis and standard Biomet/Lorenz TMJ prosthesis, which are well accepted by both physicians and patients worldwide. [ 2 , 3 ] However, there have been studies indicating that these prostheses may not be suitable in Chinese setting due to the differences in the morphological parameters of TMJ and the design of the prosthesis of Chinese population compared with the western countries. [ 4 , 5 ] At present, there have been certain studies reporting preliminary findings with respect to the application of TMJ prosthesis in China.…”

This study aimed to measure temporomandibular joint (TMJ) with 3-dimensional (3D) reconstruction technique in Chinese northeast population, and to clarify the region for fixation and to provide morphological basis for the application of TMJ prosthesis in Chinese setting. Computed tomography (CT) scan and 3D reconstruction were performed with 132 individuals. Structural markers and measurements were further performed with a 3D model of the total TMJ, including the width, thickness and angle of zygomatic arch, the width and height of articular fossa, as well as the area, width, thickness and angle of mandible in the fixation region of the TMJ prosthesis. All the measured indicators values were compared between bilateral sides and gender groups. There was no statistical difference in the measured indicators between the left side and the right side ( P > .05). However, certain parameters, including S, L5, L7, P4, and P5, were significantly different among males and females ( P < .05). In this study, 3D CT image was used to obtain the measurement data of TMJ, which provided data support for the clinical application of TMJ prosthesis in Chinese population.

“…Replacement of a TMJ with a total joint prosthesis can have a great impact on the biomechanical aspect of the contralateral joint and can affect the complex mandibular movements, which consist of both rotational and translational components 3,4,5 . Over the last few decades, a number of prostheses have been developed with the aim of reconstructing the TMJ and restoring its physiological movements, especially over the last 2 years 6 . Most of the currently available TMJ-TJRs are produced using computer-aided design and manufacturing (CAD/CAM) techniques, enabling virtual patient-specific modelling.…”

Total joint replacement (TJR) with a prosthesis can be indicated for patients with severe temporomandibular joint (TMJ) dysfunction. Surgical accuracy is necessary for correct translation of the preoperatively predicted functional outcome, wear, and biomechanical behaviour of the patient-specific TMJ-TJR prosthesis. This study describes the first clinical applications of the patient-specific TMJ-TJR prosthesis according to the Groningen principles (G-TMJ-TJR), which was developed and validated in a prior human cadaver test study. The aim of this study was to validate the accuracy of placement of the patient-specific G-TMJ-TJR in the clinical setting. It was hypothesized that a virtual surgical plan (VSP) combined with guided placement of the patient-specific G-TMJ-TJR would be performed as predictably and accurately as in the prior cadaver series. All patients who received a VSP-based patient-specific G-TMJ-TJR between December 2017 and March 2020 were included in this study. The accuracy analysis was based on postoperative cone beam computed tomography (CBCT) data. All 11 prostheses could be inserted using routine pre-auricular and retromandibular surgical approaches. Analysis of the VSPs and postoperative CBCTs showed an average three-dimensional deviation of 1.07 mm (standard deviation 0.46 mm, range 0.33-1.91 mm) for all of the fossa and mandibular components. The patient-specific G-TMJ-TJR can be applied predictably and accurately in a clinical setting.
