[Occlusal relation of upper canines in patients with complete unilateral clefts]

Aiming to evaluate the position variations of the upper canines in individuals with congenital cleft of the lip and palate which interfere in the final result of a prosthesis, we have done an analysis and a measurement of this alterations in casts of 208 patients with complete unilateral cleft before the prosthetic treatment. We have verified in the vertical direction, the infra-version and in the horizontal direction, the mesiodistal deviation of its relation of normal occlusion and the distance in relation to the mid line. The results obtained have become evident a frequent anterolateral openbite in the cleft side, besides a common deviation of the upper mid line, due to the general position of the upper canines on the side side of the cleft to the mesial.
