We have applied a three-dimensional computed tomography (3 D-CT) system clinically in 16 patients in the oral and maxillofacial region and evaluated its usefulness. Compared with a conventional radiographic imaging, we could construct a three dimensional display directly, observe it from various views, and pick up some regions without image overlapping. The 3 D-CT system is thus considered to be useful in surface researching of the bone and skin. On the other hand, we could not get enough imaging of fracture lines with little deviation or details of cancellous bone. The 3 D-CT imaging is a useful diagnostic method in the oral and maxillofacial region, but some problems on its high exposure dose and pseudoforamina still remain to study in the future. So we must be selective in its application.
