Poster 174: Bone Graft on Tooth Missing Area Using the Condyle Fragment of the Condyle Fractured Patient for Prosthetic Treatment Using an Implant: A Case Report

Abstract

It is quite common to see the maxillofacial fractures accompanying an alveolar bone fracture and tooth luxation. In particular, tooth luxation caused by an alveolar bone fracture can lead to rapid alveolar bone resorption. Therefore, horizontal and vertical alveolar bone augmentation might be required on an area with missing teeth area before implanting an implant. Depending on whether the fractured fragment has been dislocated or not, the direction of the muscle and the condition of the fracture, conservative and/or surgical treatment should be administered for a maxillofacial fracture. In particular, a condyle fracture is very difficult to approach surgically and can accompany TMJ ankylosis, disclusion caused by changes in the vertical dimension, trismus, change in occlusion and bone necrosis. Therefore, treatment should be given under an accurate diagnosis. Condyle fractures accompanying a decrease in the vertical dimension, trismus and an excess dislocation of bone fragments (Class III, V) are efficacious conditions for surgical treatment. The surgical removal of a bone fragment is essential when there is trismus but no changes in the vertical dimension. In order to help treat both a condyle fracture and an area of missing teeth, it is expected that the removed fragment can be used as a graft material on the tooth or alveolar bone lacking site. We describe a 25-year-old male patient who had a left condyle fracture, right subcondyle fracture, right mandible body fracture and left premolar region alveolar bone fracture as a result of an accident. An open reduction of the mandible body fracture, tooth extraction of the alveolar bone fracture site and fragment removal was performed on a patient. Three months after surgery, the bone fragment was removed due to trismus and acute pain caused by the left condyle bone fragment. The removed bone fragment was used as a bone graft on the alveolar bone defect site and the implant was implanted. Jaw opening movement was carried out and a prosthetic treatment was given. The mandibular functions such as masticatory movement and jaw opening movement had recovered some time after surgery.
