Condylar prosthesis for a temporo-mandibular joint

A condylar prosthesis (10) for a temporomandibular joint, with the condylar prosthesis (10) comprising:

• a mandibular implant (12), attachable with the branch (20) of a mandible (22), and
• a joint head (16), designed to serve as a substitute mandibular condyle, with the mandibular implant (12) comprising an anchoring stem (14) making possible the use of an intramedullary connection in the top (18) of the branch (20) of the mandible (22), and with a distal end (24) of the anchoring stem (14) being offset toward the front (AV) of the prosthesis (10) relative to the joint head (16) and in a median plane (PM) of the prosthesis (10),
• wherein the anchoring stem (14) follows a curved profile (PC) in its length (L14) and in the median plane (PM) of the prosthesis, with the direction of curvature (DC) of the anchoring stem (14) being oriented toward the front (AV) of the prosthesis, and
• wherein the anchoring stem (14) is topped by a spherical joint head (16).

A complete prosthesis (50) for a temporomandibular joint, comprising:

• a temporal prosthesis (52);
• and
• a condylar prosthesis (10) comprising
• a mandibular implant (12), attachable with the branch (20) of a mandible (22), and
• a joint head (16), designed to serve as a substitute mandibular condyle, with the mandibular implant (12) comprising an anchoring stem (14) making possible the use of an intramedullary connection in the top (18) of the branch (20) of the mandible (22), and with a distal end (24) of the anchoring stem (14) being offset toward the front (AV) of the prosthesis (10) relative to the joint head (16) and in a median plane (PM) of the prosthesis (10),
• wherein the anchoring stem (14) follows a curved profile (PC) in its length (L14) and in the median plane (PM) of the prosthesis, with the direction of curvature (DC) of the anchoring stem (14) being oriented toward the front (AV) of the prosthesis.
