Applicability of 3D-CT facial reconstruction for forensic individual identification

The study of anthropometric characteristics is of fundamental importance to solve problems related to identification. Craniometric features are included among these characteristics which are closely connected to forensic dentistry, since they can be used to aid in identifying an individual from a skull, found detached from its skeleton. Craniometric analysis is performed by locating the anthropometric points and determining the anthropometric measurements, which have already been established in the literature and subdivided into specific studies and can usually be obtained by simple rulers, calipers and other specific tools.

The main advantage of computed tomography (CT) is that overlaying structures can be visualized, and less attenuating structures can be distinguished from more attenuating structures. Also the axial and coronal images can be acquired, and the original data can be reformatted based on different views.
