[Bidimensional measurements of the dental arches using a digitizer]

This method is based on the photographic reproduction of plaster models of dental arches, having previously identified reference points at a canine, molar and inter-incisor level. Subsequent measurement, using a digitizer, of the distances between the above points allows a precise bidimensional measurement to be easily obtained. By selecting plaster models for the different stages of treatment, the method can also be used to monitor changes in the dimensions of the alveolodental arch induced by therapy, or the possible presence of long-term recidivation.
