Abstract

Objective: An accurate evaluation of the skeletal sagittal jaw relationship is important in orthodontic diagnosis and treatment planning. This study was done to establish cephalometric norms of all types of malocclusions using ANB angle, Wit’s appraisal, and Beta angle and evaluate the significance of W angle compared to these parameters.  

MethodsNinety pre-treatment lateral cephalograms of male and female patients aged 18-28 years from Sulaimani city that met the sample criteria were traced digitally by the Easy Dent 4 software program. The sample was divided into three groups of skeletal malocclusions, class I, II, and III, by the two-finger method of Foster initially. It was later confirmed cephalometrically by ANB angle, Beta angle, and Wit’s appraisal; each group consisted of 30 patients. Also, for each subject, the W angle was measured.      

Results Significant differences were found in the ANB angle, Beta angle, Wit’s appraisal, and W-angle in all 90 patients. The coefficient of variability showed that Wit’s appraisal was the most variable parameter and W angle was the least variable parameter.  

ConclusionsANB angle, Beta angle, Wit’s appraisal, and W-angle are significant parameters to assess the sagittal jaw relationship. The use of W angle and other parameters can provide a more accurate assessment of the sagittal skeletal jaw relationship as it has the least coefficient of variance; it should therefore enable better diagnosis and treatment planning for patients.                                                                                     


Keywords:  Skeletal sagittal jaw relationship, W Angle, ANB angle, Beta angle, Wit’s appraisal.
