Abstract
The prosthetic temporomandibular implant () comprises a concave surface () and a convex surface () designed to cooperate, respectively, with the natural outer surface () of the condyle () and the natural inner surface () of the fossa () of a damaged joint () of a human mandible (). It is made of a rigid biocompatible material such as ceramic, stainless steel or an aluminum/zirconium alloy. The implant is designed based on an image of the joint () generated by a medical imaging system and incorporating an image of a healthy joint (); these three-dimensional images are processed by a CAD (segmentation, vectorization) system to obtain a vector representation of the implant () and a data file capable of controlling a digital milling machine. The invention is applicable to the restoration of a damaged TMJ ().
