Abstract

The working group on osteosynthesis questions (AO) craniomaxillofacial (CMF) trauma classification distinguishes nine anatomic subregions in the diagnostics of mandibular fractures. The diagnostic capabilities of cone beam computed tomography (CBCT) in terms of classification criteria in non-condylar (regions with the exception of the articular process) and condylar mandibular fractures are exemplified in three cases. With clinical symptoms and signs suggestive of mandibular fracture it is good practice to scrutinize all tomographic layers and planes in a systematic fashion to identify reliable indictors for loss of osseous continuity. In contrast to conventional x-ray techniques CBCT provides deeper insights (multiplanar and 3-dimensional) into the mandibular bony structures and gives additional information about hidden or obscured fracture lines, the grade of fragmentation and the extent of displacement. Blurring and distorting overlay effects are eliminated therefore increasing the diagnostic reliability. This then corresponds with the demands for high accuracy of the classification and underlines the suitability of CBCT imaging for a refined fracture diagnosis of the mandible even within precision level 3.
