Abstract

Background:  This study is on the basic measurement of the palatal depth, maxillary and mandibular arch widths and circumferences in three groups: class I open bite, class I deep bite and class I normal occlusion, and to compare the results among the three groups. Material and methods: Seventy two sets of casts divided into 3 groups (class I open bite malocclusion, class I deep bite malocclusion and class I normal occlusion) were used. Palatal depth, maxillary and mandibular arch widths and arches circumferences were measured using a sliding gauge caliper, readouts were rounded to 0.1 mm.   Result: Palatal depth was the highest in open bite followed by normal and then in deep bite. The intermaxillary widths were the highest in normal occlusion followed by deep bite and then open bite. No significant differences were seen in the mandibular widths among the three groups. Correlation coefficient among variables expressed considerable variation.

Keywords: Palatal depth, open bite, deep bite.
