[A new method for measuring dentition segments and the diagnosis of their occlusion]

A new method for evaluation of dentition during occlusion is suggested (2001). Thirty patients with normal occlusion were examined. Dental occlusion was evaluated for the frontal and lateral segments. Frontal and lateral (right and left) segments of the upper and lower teeth were examined, The upper and lower segments differed in size: the mean size of the upper frontal segment was 37.7 +/- 1.7 mm, that of the lower frontal segment 36.2 +/- 1.7 mm. The proportionality index was 1.04. The lateral segments of the upper and lower teeth were equal, their mean size being 20.2 +/- 0.8 mm. Hence, measurements of dentition segments during occlusion help evaluate their proportionality and detect changes in their sizes in patients with maxillodental abnormalities.
