Abstract

Objective: To determine the association between anterior alveolar dimensions and sagittal jaw relationship.

Methodology: This Cross-sectional study took place in Orthodontic Department, Institute of Dentistry, Liaquat University of Medical and Health Sciences, Jamshoro from August 2018 to January 2019. All the subjects, as per ANB angle, were grouped into three categories as (Class I = value between 1° and 4° for ANB angle), (Class II = value > 5° for ANB angle) and (Class III= value <1° for ANB angle). All the data was recorded in the Performa for the purpose of analysis.

Results: Total 90 patients were studied; their average age was 21.12+3.47 years and 52.2% were females. Mean upper posterior alveolus width was significantly higher in sagittal class II as 12.69 ± 5.52 than the sagittal class I and III p-value 0.058. Mean upper anterior alveolus height was found to be significantly greater in class I and III in contrast to class II p-value 0.028. Mean lower anterior alveolus width was insignificantly related with sagittal classification, p-value 0.343. Mean upper anterior alveolus width and lower posterior alveolus width were insignificantly related to sagittal classification, p-value were quite insignificant. Sagittal class II and III were significantly associated with female gender 0.021, while class I was linked to male gender p-value 0.021.

Conclusion:  There was a significant association between dimensions of anterior alveolar among different vertical and sagittal jaw association.
