| Popis: | In orthodontics, various methods of assessing sagittal jaw base relationship are formulated. Earlier, skeletal pattern was analyzed only clinically; however, after the introduction of cephalometrics by Broadbent and Hofrath in 1931, ANB and Beta angles are being used to describe skeletal discrepancies between the maxilla and mandible. YEN angle has also been used as a sagittal dysplasia indicator after its introduction in 2009. The aim of our study is to assess the predictability of ANB, Beta, and YEN angles as anteroposterior dysplasia indicators in skeletal class II malocclusion in Gulbarga population. This study is an attempt to check the variation as well as correlation existing between these 3 parameters, so that a more presumable and least variable parameter can be obtained. Total of 70 lateral cephalograms of skeletal class II patients were selected based on Down’s facial angle and tracing was carried out manually to measure ANB, Beta, and YEN angles. Statistical analysis was carried out to assess the coefficient of variation and the Pearson coefficient. Our study concluded that YEN angle is highly predictable and a homogenously distributed angular parameter used to assess sagittal discrepancy in class II patients compared to ANB and Beta angles. |
