Idiopathic Condilar Resorption after Bimaxillary Orthognathic Surgery.

Abstract

Idiopathic Condylar Resorption (ICR) is an alteration of the Temporomandibular Joint that causes the slow and progressive resorption of the mandibular condyle without an apparent cause. It is observed after orthodontic treatment or orthognathic surgery. Clinically Idiopathic Condylar Resorption is manifested with a progressive development of an anterior open bite, a posterior rotation of the jaw, Class II molar and canine relationship, retrognathia and TMJ pain or dysfunction. The treatment for this alteration may be orthodontics, occlusal splints, analgesics, and orthognathic surgery with or without condylar reconstruction with cost chondral or alloplastic graft once, condylar activity has ceased.

We present the clinical case of a 24-year-old female patient with a diagnosis of Idiopathic Condylar Resorption. Clinically it presented open bite, laterognasia and refers to TMJ pain and bimaxillary orthognathic surgery two years ago. We performed complementary examinations. It was conclude that the condylar resorption had ceased, therefore, the patient was underwent orthodontics for unimaxillary orthognathic surgery (Intraoral Vertical Ramus Osteotomy).
