ABSTRACT:The aim of the paper is to compare the W angle along with other sagittal relationship parameters such as ANB angle, Wits appraisal, Beta angle, so as to obtain more reliable parameter for antero-posterior cephalometric analysis. The Materials and Methods used are a Sample comprised of 99 pre-treatment lateral cephalograms of Hyderabad subjects which were divided into 3 groups: Group I- Class I skeletal pattern (n=33), Group II- Class II skeletal pattern (n=33), Group III – Class III skeletal pattern (n=33) and traced for different sagittal relationship parameters. The age of subjects were ranged from 15-30 years. The results obtained from the t-test analysis was performed and highly significant differences were found in ANB angle, Beta angle and W-angle in all the 99 patients. Coefficient of variability was calculated for intra-group comparisons. Wits appraisal was found to be highly variable parameter and W angle was found to be the least variable parameter. In both study groups, ANB angle correlated significantly positively with Wits appraisal while beta angle showed significant negative correlation with ANB angle and Wits. In class II subjects, a significant negative correlation was also seen between ANB angle and W angle. From the above study it is concluded that ANB angle, Beta angle and W-angle are significant angles to assess the sagittal jaw relationship between maxilla and mandible. W angle showed highly significant results. However, instead of relying on one single parameter, others also should be checked and should be correlated with clinical findings.
