Abstract :

The study was performed to compare maxillary first molar horizontal and vertical distances on the basis of sagittal and vertical skeletal growth patterns on lateral cephalograms of adult patients having different dentofacial discrepancies. For the study, 45 Lateral cephalograms (20 male, 25 female) which were divided as Skeletal (15 Class I, 15 Class II, 15 Class III) and as Vertical growth (20 normodivergent, 10 hypodivergent, 15 hyperdivergent). For evaluation of sagittal skeletal features ANB and occlusal features were utilized. For evaluation of vertical skeletal features Jarabak values were used. The horizontal position of the upper first molar was evaluated considering the distance of its distal aspect to the vertical pterigomaxilar line, while the vertical position was evaluated considering the distance perpendicular to the Frankfurt plane at the level of the occlusal plane. . ANOVA test was used to determine the molar position in the different groups with respect to sagittal and vertical patterns. Results: The molar vertical position was not significantly affected by sagittal and vertical facial growth type, age or their interaction. The first molar horizontal position was 1.8 mm more posterior in Class III and 3.17 mm more anterior in Class II compared with Class I (20.73mm)
