Prosthetic device for temporomandibular joint and corresponding prosthetic assembly

Prosthetic assembly for temporomandibular joint comprising a prosthetic device and a guide device

• wherein said prosthetic device includes a first prosthetic component, able to be associated with a mandibular condyle of a patient, and a coordinated second prosthetic component, able to be associated with a respective glenoid fossa of said patient, wherein said first prosthetic component is configured to cooperate with said second prosthetic component to define said temporomandibular joint and comprises a concave portion, defining a coupling seating [having a shape mating with the shape of said mandibular condyle, wherein said first prosthetic component includes at least one anchoring element projecting from, and attached at least to, said concave portion, being contained in said concave portion, said anchoring element having a main extension along a latero-medial axis and being configured to be inserted into a mating anchoring seating present on said mandibular condyle, and in that said coupling seating is at least partly open along said latero-medial axis, and
• wherein the guide device includes a central body able to be positioned against at least the upper lateral part of a mandibular condylar branch, and a guide wall associated at the upper part with said central body and having the profile of the osteotomy to be performed on said condyle, wherein a groove extends vertically from said guide wall toward said central body, and in that said groove is open at the upper part and is through in a direction parallel to a latero-medial axis, and in that said groove has a depth substantially the same as a height of a lamella which acts as an anchoring element of said prosthetic device.
