Relationship between dento-facial vertical proportions and overbite part 1 Deep overbite

Abstract

Malocclusions associated with a deep overbite are difficult to treat. We investigated various factors associated with deepbite malocclusion. Standardized lateral cephalograms were taken on 60 adult females who had deep overbite with their teeth in occlusion. Vertical, horizontal and angular measurements were recorded. We then determined the degree of correlation between the overbite and 55 variables. Previous reports supported the findings of our study that there is a strong correlation between the vertical position of the maxillary incisors, the interincisor angle, and the overbite. we also found that the curve of Spee must be taken into consideration when correcting the interincisor angle because there is a correlation between the interincisor angle. Our results show that orthodontists must first reduce the overbite in the cuspids before controlling the deep overbite in the incisors.
