Association of Anterior Alveolar Dimensions with Different Sagittal Jaw Relationships
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.
Patients of both genders ranging in age from 18 to 30 years were included. 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: A total of 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 in sagittal class I and III p-value 0.058. The 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, and the 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.
