3-DIMENSIONAL CT OF THE DENTITION AFTER SUBTRACTION OF BONE

Owing to computer programs, computed tomography allows obtaining sections of the facial structures in all spatial planes and to << pile up >> all sections to reconstruct the structural unit studied. In addition, these images can be reconstructed by selecting a density threshold, for example that of dentin or of enamel, isolating those from their bony environment, and thus the patient's dental arch can be visualized as if one was manipulating a pair of dental models. The first results obtained with this technique are presented, and they seem to be highly promising.
