Orthodontic Treatment Accompanied by Temporomandibular Joint Replacement in a Patient with Occlusal Collapse due to Unilateral Condylar Resorption

This case report presents the interdisciplinary management of a patient with occlusal collapse resulting from unilateral condylar resorption. The patient presented with facial asymmetry, posterior bite collapse, and significant periodontal breakdown on the affected side. To restore mandibular structure and function, unilateral temporomandibular joint (TMJ) replacement was performed. After confirming periodontal stability through comprehensive periodontal therapy, orthodontic treatment was initiated to upright the severely inclined dentition and close residual spaces using controlled mechanics adapted to compromised periodontal support. Through this staged, multidisciplinary approach—including surgical, periodontal, and orthodontic interventions—functional occlusion, facial symmetry, and skeletal harmony were achieved, demonstrating a favorable esthetic and functional outcome with long-term prognosis.
