Abstrakt: Introduction: We report the successful treatment of a 38-year-old woman with bilateral idiopathic condylar resorption and anterior open bite. She had incompetent lips, a gummy smile, increased lower facial height, high mandibular plane angle, skeletal and dental Class II malocclusion with mild mandibular crowding, increased overjet, and mandibular midline deviation to the right.
Methods: The treatment plan included: (1) presurgical alignment and leveling of the teeth in both arches; (2) jaw motion tracking (JMT) to detect mandibular movement; (3) 3-piece maxillary osteotomies with mandibular reconstruction and bilateral coronoidectomies; and (4) postsurgical correction of the malocclusion. The orthodontic treatment was performed with the use of custom lingual braces and clear brackets and the orthognathic surgery was planned with the use of virtual surgical planning.
Results: The idiopathic condylar resorption and anterior open bite were treated, crowding was eliminated in the lower anterior segment, correction of skeletal and dental Class II malocclusion was obtained, mandibular plane angle was reduced, and facial profile improved.
Conclusions: The results suggest that esthetic and functional results can be achieved with the cooperation of 2 specialties and with the use of state-of-the-art technology.
