Temporomandibular joint alloplastic reconstruction of post-traumatic joint degeneration with Sawhney Type I ankylosis using 3D-custom GD-condylar cap prosthesis to restore condylar form and function.

Abstract Temporomandibular Joint (TMJ) ankylosis as a sequelae following hemarthrosis from trauma, middle ear infection and progressive debilitating arthritis of various etiologies has been well understood, but challenges always arises in terms of choosing least morbid procedure with maximum functional outcome. Total joint replacement (TJR) is the common final stage correction mandating extensive surgical exposure with good technical expertise with its limitations of risk of failure and complications. A case of post-traumatic TMJ degeneration with ankylosis reconstructed using a customized GD-condylar cap prosthesis is described. The patient had an uneventful post-operative period with acceptable functional outcome. Conclusion The condylar cap prosthesis is a bio-compatible and biomechanically designed in such a way that it can be used in indicated cases by performing minimally invasive surgical technique to achieve optimal functional and esthetic outcome.
