Advances in Application of CBCT in Diagnosis and Guidance of Operation Designing of Mandible Fracture

摘要

The purpose was to illustrate and discuss the importance of cone beam computed tomography (CBCT) for accurate diagnosis of mandible fracture and designing of surgery. Two cases of mandible fracture were selected in this report. The history of patients revealed traumatic injuries on their faces because of accidents. The patients were primarily examined with 2D panoramic radiography which did not provide adequate information. Both cases were thereafter investigated preoperatively with CBCT. As the results, CBCT showed the displacement of fracture ends clearly which were useful for diagnosis and designing of surgery. We concluded that CBCT allowed accurate diagnosis of mandible fractures and also provided guidance for operational design.
