3-DIMENSIONAL CT OF THE DENTITION AFTER S UBTRACTION OF BONE

Owing to computer programs, computed tomography allows obtaining secti ons 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 bo ny environment, and thus the patient's dental arch can be visualized a s if one was manipulating a pair of dental models. The first results o btained with this technique are presented, and they seem to be highly promising.
