IntroductionThe temporomandibular joint (TMJ) is a complex joint, and it allows bilateral synchronous rotatory and translatory movements. TMJ reconstruction has evolved as an important step in the management of conditions affecting the TMJ like ankylosis, traumatic injuries and congenital deformities. Distraction osteogenesis (DO) is a biological process of forming new bone and adjacent soft tissues by gradual and controlled traction applied on osteotomized bone segments.Case reportHere is a case report of bilateral TMJ ankylosis which was managed effectively by resection of ankylotic mass and reconstruction of TMJ by transport distraction osteogenesis with preoperative vector planning using a 3D printed model.ConclusionDistraction osteogenesis can be considered as an effective means of condylar reconstruction for an anatomical and functional TMJ with minimal complications. Use of 3D models can help making such complex TMJ reconstruction procedures simpler.
