AbstractAim- To test the reliability of three different alternative points to point A in class II division 1 and division 2 malocclusion.
Material and method- The study was conducted on 120 Left lateral cephalogram on the basis of ability to locate point A with considerable degree of accuracy.The sample was divided into two groups:Group 1 consisted of 60 class 2 division 1 lateral cephalogram and group 2 consisted of 60 class 2 div 2 lateral cephalogram.Three alternative methods for point A estimation were evaluated for reliability in vertical and horizontal planes.
Results and Discussion- Point A2 was the most accurate in both the vertical and horizontal planes and both A2 and A3 can be used in the vertical plane as an alternative to Point A.
Conclusion- Point A2 is the best reliable substitute to point A and A3 being the least dependable in both the groups for assessment of sagittal jaw relationship.
