Application of virtual three-dimensional surgery planning in management of open bite with idiopathic condylar resorption

This case report describes the successful treatment of an adult patient with idiopathic condylar resorption and Class II skeletal open bite malocclusion and temporomandibular joint disorder. A segmental Le Fort I bilateral osteotomy, ramus increasing length inverted L–osteotomy, and genioplasty combined with orthodontic treatment were performed. The treatment plan and surgery was aided by three-dimensional medical modeling, and we managed to resolve functional, esthetic, and pain concerns to a satisfactory level.
