This case report describes the successful treatment of a 14-year-old girl with severe bilateral idiopathic condylar resorption and resultant mandibular retrusion, increased overjet, and anterior open bite. The nonextraction treatment plan included (1) aligning and leveling the teeth in both arches, (2) performing Le Fort I maxillary osteotomy, bilateral condylectomy, and mandibular joint replacement, and (3) postsurgical correction of the malocclusion. The orthodontic treatment was initiated with the use of custom lingual appliances followed by orthognathic surgery planned with virtual surgical planning. Patient-fitted and customized temporomandibular joint implants were designed and manufactured based on the patient's stereolithic bone anatomic model. Treatment was concluded with detailed orthodontic finishing. Optimum esthetic and functional results were achieved with the cooperation of 2 specialties and the use of state-of-the-art technology.
