Popis:	Objective : The purpose of this study was to compare incisor, molar and anterior facial height in normal, Angles Class II Division 1 and Class III malocclusion on lateral cephalograms. Materials and methods: Sample consisted of total 60 lateral cephalograms of the patients between the age of 16 and 32 years comprised of 20 each of normal, Angles Class II Div 1 and Class III malocclusion. Results: After studying specific landmarks and planes in the cephalograms, it was concluded that anterior facial height is significantly small in Class II Div 1, compared to normal and Class III. A fair degree of constancy of upper and lower face heights has been found in the study. It was also found that the upper molar height is contributory to increase and decrease in vertical proportions of face. Lower molar height can be related to the degree of overbite in Class II Div 1 case.
