Clinical outcomes and functional recovery after temporomandibular joint replacement: a six-month follow-up study

International audienceTemporomandibular joint replacement (TMJR) is recognized to solve pain and functional limitations when other less invasive strategies failed. TMJR consists in condyle osteotomy (leading to the section of the lateral pterygoid muscle) followed by the fixation of the fossa and the mandibular components. The surgery leads to immediate pain relief and a progressive increase of the mouth opening, assessed by the gap between the upper and lower incisal teeth. Other parameters were rarely considered such as the trajectories of mandibular landmarks (Wojczynska et al. 2019). Our study combines the assessment of the quality of life (QoL) outcomes with quantitative functional measurements – electromyography (EMG) of the masticatory muscles and 3 D mandibular motions – in order to evaluate the mid-term effects of TMJR

Evolution of the activity of the masticatory muscles before and after temporomandibular joint replacement: a clinical and functional study

International audienceTemporomandibular joint replacement (TMJR) is the last resort in the management of end-stage TMJ disorders or diseases. There is a clear consensus about the indications for TMJR and a recent increase of the studies concerning the clinical outcomes (Johnson et al. 2017). The functional recovering, after the surgery, is usually assessed by the maximal incisal opening, but few studies have investigated other functional aspects (Wojczynska et al. 2019). Our goal is to analyse the 3 D kinematic analysis of the mandible combined with electromyography (EMG) of the masticatory muscles to study the functional abilities before and after total TMJR. This paper focuses on the evolution of the muscular activities before and after the surgery, for two patients followed during one year and compared with an asymptomatic group

Subject-specific numerical estimation of the temporomandibular joint reaction force during mouth opening and closing movements

International audienceThe temporomandibular joint (TMJ) is composed by the mandibular condyle, the temporal fossa and an articular disc in between. The TMJ can beseriously damaged as a result of bone or dental disorders. To perform joint reconstruction and design prostheses, there is a need to better understand the TMJ 3D kinematics to estimate the joint reactions and disc contribution. In the literature, mandibular movements were used to describe TMJ kinematics but the studies have been carried out on small groups (<30) [1-4]. Besides, coupled studies of TMJ kinematics and dynamics are rather rare. Finally, no comparison of healthy and pathological subjects was done. This work aims to analyze TMJ kinematics and dynamics for large groups of asymptomatic and toothless subjects
