Abrégé
(EN)
The temporomandibular prosthetic implant (10) comprises a concave surface (16) and a convex surface (17) that are designed to cooperate, respectively, with the natural outer surface (9) of the condyle (5) and the natural inner surface (7) of the fossa (8) of a damaged articulation (2) of a human mandible (1). It is made of a biocompatible rigid material, such as ceramic, stainless steel or an aluminium/zirconium alloy. The implant is designed in accordance with an image of the articulation (2) that has been generated by a medical imaging system, and taking into account an image of a healthy articulation (3), by processing these images in three dimensions on a CAO system (segmentation, vectorization) in order to obtain a vectorial representation of the implant (10) and a data file for controlling a digital drill. Application to the restoration of a damaged temporo-mandibular articulation (2).

L'implant prothétique temporo-mandibulaire (10) comporte une surface concave (16) et une surface convexe (17) destinées à coopérer respectivement avec la surface externe (9) naturelle du condyle (5) et la surface interne (7) naturelle de la glène (8) d'une articulation (2) endommagée d'une mandibule (1) humaine. Il est en matériau rigide bio-compatible, tel que la. céramique, l'acier inoxydable ou un alliage aluminium/zirconium. L'implant est conçu en fonction d'une image de l'articulation (2) générée par un système d'imagerie médicale, et en tenant compte d'une image d'une articulation saine (3), grâce à un traitement de ces images en trois dimensions sur un système de CAO (segmentation, vectorisation) afin d'obtenir une représentation vectorielle de l'implant (10), et un fichier de données capable de piloter une fraiseuse numérique. Application à la restauration d'une ATM (2) endommagée.
