    Abstract

    History is evident that correct assessment of Sagittal Jaw Relationship has always remained the perennial problem in orthodontics. The present study is undertaken to use Sagittal methods for assessing individuals and classifying for Skeletal Class I, Class II and Class III based on Jaw Relationship and to evaluate the reliability of sagittal methods. 200 subjects in the age group of 12 to 18 yrs were selected and were subjected to cephalometric radiography and traced. The sample was divided into skeletal Class I, Class II and Class III on the basis of AXD angle, FABA angle and MM Bisector. Subsequently following angles and linear measurements were measured; Beta angle; AB plane angle; JYD angle; ANB angle; AXB angle; AF - BF and App - Bpp. Result - Consistency could be demonstrated by all the methods assessed by Antero-Posterior jaw relationship. Insignificant difference on influence of growth, age and sex was noted. Angular methods used for assessing jaw relationship such as FABA, AXD, Beta and linear measurements such as App-Bpp, MM Bisector could demonstrate superiority for assessing Antero-Posterior jaw relationship over other methods such as AXB, AB plane, ANB and AF-BF which showed more variability.
