Introduction:

We present our experience and case series in which we used a TMJ prosthesis designed and developed in Spain by Dr. Carlos Goizueta (Hospital Sant Joan d'Alacant), together with the Technological Institute of Canarias and Maxilaria

Materials and methods:

Patients diagnosed with temporomandibular joint pathology who were reconstructed with a TMJ prosthesis. This prosthesis has four components, two of the articular fossa (one part of titanium and the other part of polyethylene) and two of the body of the device (condylar head of cobalt-chrome and ramus of titanium).

Results:

We present the preliminary results of the patients reconstructed with a TMJ prosthesis in the past 2 years in our center. A total of 8 prosthesis were place in 6 patients. The diagnosis of the patients was TMJ ankylosis in 4 cases, and severe TMJ dysfunction in the other 2 cases. An improvement of both pain and also mouth opening was observed after a follow-up of at least 6 months.

Conclusion:

This TMJ prosthesis, developed in Spain, has many advantages, such as the possibility of replacement of some of the parts, as well as its design since the masticatory forces are transmitted to the mandibular ramus and not to the screws of the device.
