Avaliação dos efeitos da cirurgia ortognática e da prótese de ATM a curto e médio prazos.

Abstract

Dentofacial deformities and internal disorders of the temporomandibular joint (TMJ) are problems that can have a great impact on the patient's life, and often these two alterations can be correlated. The elaboration of a treatment plan for dentofacial deformities must involve a meticulous clinical evaluation of face, occlusion, and temporomandibular joints. Dysfunctional temporomandibular joints should be carefully evaluated and, if necessary, treated before or concomitant with orthognathic surgery, when this one is indicated. The treatment of these dysfunctions is based on the degree of involvement and vary from conservative treatment to replacement of the joint by a total prosthesis. The objectives of this study were to evaluate the impact of orthognathic surgery with advancement and counterclockwise rotation of the maxillomandibular complex on the airway and cervical spine, to evaluate the main complications associated with surgery for the installation of a TMJ total prosthesis, and to report a case of a patient submitted to several treatments for internal derangement of the temporomandibular joint, being finally treated with the TMJ total prosthesis. The results showed that both orthognathic surgery and the surgical procedure for installing the TMJ prosthesis are safe and stable, being able to improve the functional capacity of patients.
