Comparison of posterior tooth angulation in patients with normal bite and deep bite malocclusion

Abstract

Introduction: Malocclusions should not be always considered as disease entities but, they should be observed as expression of an underlying inconsistencies. The aim of the study was to compare the angulations of posterior teeth in patients with normal bite and deep bite malocclusion.

Material and methods: Lateral Cephalometric analysis of 194 deep bite (38 male,59 female) and normal bite (39 male,58 female) with 97 untreated subjects in each group were compared having permanent dentition. statistical analysis was performed using descriptive analysis and intergroup comparison. Were performed through t tests. The results were considered significant at, p.value ≤0.05

Results: There was significantly greater distal angulation of mandibular first premolar and mandibular second molar in relation to mandibular plane in deep bite malocclusion group than those with normal occlusion.

Conclusions: There was a significant difference between posterior tooth angulation in normal occlusion and deep bite malocclusion, the mandibular first premolar and second molar had greater distal angulation in relation to mandibular plane.
