Relationship between dento-facial vertical proportions and overbite in Taiwanese

Abstract

We investigated various factors associated with deepbite malocclusion, which is generally thought to be difficult to treat. Standardized lateral cephalograms were taken on 60 adult Taiwanese females who had deep overbite when their teeth were in occlusion. We recorded vertical, horizontal and angular measurements and determined the degree of correlation between the overbite and 46 variables.
Previous reports supported the findings of our study that overbite has a strong correlation with the vertical position of the canines and the inclination of the maxillary canines.
Our results showed that orthodontists must first reduce the overbite in the canines before controlling the deep overbite in the incisors.
