Morphometric parameters of brachygnathic dental arches considering size of permanent teeth

Abstract

The study involved 257 individuals with physiological occlusion of their permanent teeth and the brachygnathic shape of the dental arches. The outcomes revealed a certain dependence between the major linear parameters of brachygnathic dental arches and the size of the permanent teeth. The main indicator of the brachygnathic dental arch is the dental arch index (the ratio of the depth of the arch to its width), which was below 0.71. Visually these types of arches are defined as “short” and “wide”. The feature typical of those with brachygnathic normodontia and microdontia include front teeth retrusion and low values of vestibular-lingual inclination of the teeth.
