Abstract

  • This case report describes the successful second surgical treatment of a 26-year-old white female patient with a retrognathic mandible and previous bilateral total joint prostheses placement. The patient had previously presented with bilateral idiopathic condylar resorption (ICR) which caused clockwise mandibular rotation and resulted in anterior open bite and a retrognathic mandible. The patient had undergone definitive corrective for the ICR where condylectomies were performed bilaterally. In addition, total joint prostheses using 'stock joints' were used to restore the condyle and glenoid fossa on both sides. Although the previous surgery corrected the anterior open bite and restored the condyles, the patient was still suffering from joint symptoms (significant pain), restricted mandibular movements, increased overjet (12 mm) and a retrognathic mandible. The treatment plan included a combined orthodontic surgical approach: (1) bimaxillary orthognathic surgery: a surgical procedure on the mandible to reposition the prosthetic joints and correct the mandible position, and a segmental LeFort I to expand the maxilla; and (2) post-surgical orthodontics treatment to detail the occlusion. At the end of the treatment, good aesthetic and functional results were obtained with the cooperation of two specialties. This case emphasises the importance of three-dimensional planning and multidisciplinary treatment when addressing complex jaw movements. It also emphasises the importance orthodontic planning and collaboration with the orthodontist.
