Abstract
Objective was to show a clinical case of a patient with degenerative temporomandibular joint (TMJ) disorder by means of volumetric computed tomography (CT) before and after the intervention. A female patient, 65 years old, presented with sudden malocclusion with contact on only 2 teeth, 1 on each side, from a recent open bite, crackling on the left side of TMJ. Magnetic resonance imaging of the TMJ presented a displacement of the disk without recapture. CT of the TMJ presented erosion of the articular surface of the condyle and left fossa, and erosion of the right condyle with osteophyte. She was diagnosed with right side arthralgia, disk displacement without reduction, and degenerative disorder more pronounced on the left side. We performed viscosupplementation of hyaluronic acid, low intensity infrared laser therapy, and use of stabilizing occlusal splint. Comparative CT imaging showed bone remodeling on the left side and a more centered positioning of the condyle on the left side in relation to the joint fossa.
