ABSTRACT

The mandible is a bone from the face that contributes to facial contour. It is directly involved in occlusion, mastication, articulate speech, and the airway, so a damage to this structure can be caused by an accident, pathology, firearms projectile, osteomyelitis and others. The mandibular reconstruction is the restoration of its dentition and soft tissue. The autologous bone graft is the principal treatment. Wide defects need bigger bone graft so that is why anterior iliac crest is ideal because of its technique, low morbidity and the availability. In regard to the reconstructed structural evaluation, the Cone-Beam tomography is the best option to identify bone changes. Objective: To evaluate the stability and the anterior iliac crest graft reabsorption rate in Cone-Beam tomography of patients that were submitted to mandibular reconstruction of total resection treated by the Oral and Maxillofacial Surgery service at "Dr Domingo Luciani" Hospital. Material and methods: This research work is an observational type, longitudinal and retrospective. The sample is comprised by the patients that were submitted to a mandibular total resection surgery, extraction and application of anterior iliac crest graft for immediate reconstruction that accomplished the inclusion requirements. Conclusions: It was found that the anterior iliac crest graft reabsorption rate had an assorted action. The height was inversely proportional to the width, since there was a significant loss in height and an increase in the width of the graft.
