The invention relates to a prosthetic device for temporomandibular joint and a related prosthetic kit comprising a guide device for the preparation of a suitable bone housing seat. This device is customized and built from time to time on the patient’s anatomy, with the custom-made technique. The study takes place with a virtual planning which is followed by a simulation of the surgery and is drawn on the patient’s anatomy both the cutting template (guide device) and the custom prosthesis which is then produced through 3D printing (3D printing) The invention allows considerably decrease the invasiveness of the surgical operation necessary to apply the prosthesis in the patient and consequently decrease the possibility of complications. These features also allow to increase the number of patients on whom the prosthesis can be usefully applied.

Technical features

The temporomandibular joint prostheses are essential to allow the functionality of the temporomandibular joints to be restored to patients with pathologies that have compromised their functions. These pathological states are often seriously disabling and the possibility of applying a prosthesis is often the only option that allows the return to a normal life. The invention consists of a simpler custom-made prosthesis made up of fewer components than the solutions currently in use. These features allow the prosthesis to be applied with a much less invasive surgical operation for the patient, greatly reducing the possibility of complications. The easier installation of the prosthesis also allows to increase the number of patients on whom it is possible to proceed with the operation, allowing more people to exit from a state of serious disability.

Possible Applications

  • Prosthesis designed for patients with pathologies that compromise the functionality of the temporomandibular joints.


  • Small size and fewer components;
  • Applicability to more clinical cases than state-of-the-art prostheses;
  • Custom prosthesis;
  • Greater safety of the surgical operation.
