Distraction Osteogenesis and Customized Temporomandibular Joint Prosthesis in the Reconstruction of a Large Mandibular Defect - A Case Report.

The Rationale: Mandibular resections involve esthetic and functional impairment and impose a challenge during the reconstruction. This case report is a successful reconstruction with distraction osteogenesis (DO) and customized temporomandibular joint (TMJ) prosthesis.

Patient Concerns: A 51-year-old male patient presented with a complaint of facial asymmetry, mastication, and speech difficulties.

Concomitant treatment of mandibular ameloblastoma and bilateral temporomandibular joint osteoarthritis with bone graft and total joint prostheses.

Temporomandibular joint (TMJ) osteoarthritis is a degenerative disease that can create clinical problems in the masticatory musculature, jaws, occlusion, and other associated structures and is commonly accompanied by inflammatory changes and pain. Many cases of TMJ dysfunction can be managed with nonsurgical therapies, but patients with irreversible TMJ damage may require surgical intervention for repair or reconstruction. Despite various methods of TMJ reconstruction, the patient-fitted total joint prostheses may be the best option to achieve good outcomes.

Condylar hyperplasia of the temporomandibular joint: types, treatment, and surgical implications.

Condylar hyperplasia (CH) is a progressive and pathologic overgrowth of either or both mandibular condyles, which can affect the neck, ramus, or body of the mandible. It may lead to facial asymmetry, malocclusion, speech, and masticatory problems. Identifying the specific type of condylar hyperplasia is crucial.

Management of ankylosed maxillary canine with single-tooth osteotomy in conjunction with orthognathic surgery.

Ankylosis of teeth is the abnormal adherence of alveolar bone to dentin or cementum. Ankylosis of a submerged maxillary canine can be challenging when striving for an optimal occlusal and esthetic treatment outcome with orthognathic surgery. If an ankylosed tooth does not respond to orthodontic forces, surgical procedures may be indicated to facilitate movement of the tooth to the correct position including a single-tooth segmental osteotomy to reposition the alveolar bone including the ankylosed tooth.
