E-mail : tpchaturvedi @rediffmail.com The aim of this study was to evaluate and compare dentoalveolar compensations in various skeletal dysplasias Methods: The sample consisted of 130 lateral head cephalograms of subjects age ranged between 15-24 years with a mean age of 19.5 years .. The sample was divided into four groups according to antero-posterior skeletal relationships as follows-Control Control: Group comprising Normal occlusion and other three groups were of different malocclusions. Groupol comprising of Skeletal Class-I malocclusion, Group-II comprising of Skeletal Class-II malocclusion and Group-Ill-comprising of Skeleta l Class-III malocclusion based upon the Wit's appraisal, APP-BPP measurement and IJ-angle measurement, collectively. In this study dentoalveolar linear and angular measurements have been measured on the traCing of lateral head Cephalogram.
