Abstract

Objectives: The aim of the study was to investigate the thickness of maxillary and mandibular labial alveolar bone overlying incisors and the incisal inclination in different vertical facial patterns using cone-beam computed tomography.

Subjects and methods: Eighty-one CBCT scans were carried to evaluate thickness of the labial alveolar bone overlying maxillary and mandibular incisors and the incisal inclination for the following groups: Group I: normal vertical facial pattern. Group II: low vertical facial pattern. Group III: high vertical facial pattern.

Results: Low angled group showed a higher Labial Alveolar Bone thickness in the maxillary and mandibular arches than Normal and High angled groups. High group showed a higher inclination than Normal and Low groups. The inclination of the lower incisors according to L1/MP there was a statistically a non-significant difference in mean inclination in the three groups.

Conclusion: The thickness of the Labial Alveolar Bone was greater in both the upper and lower jaws for people with a low angle than for those with a normal or high angle. People with a high angle had more inclination than those with a normal or low angle. The inclination of the lower incisors according to L1/MP there was a statistically a non-significant difference in mean inclination in the three groups.
