Abstract

The aim of this study was to compare the cephalometric measures involving FMA (Frankfurt Mandibular Plane Angle), FMIA (Frankfurt Mandibular Incisor Angle), and occlusal plane angles (Frankfurt horizontal plane - occlusal plane) for cephalometric tracing by using anatomic and metallic porion points. Cephalometric tracing was performed in thirty head lateral teleradiographs divided into two groups. The anatomic porion point was marked in group 1, whereas metallic porion point was marked regarding the Frankfurt horizontal Plane (FHP). All measures were analysed. The mean values for FMA (32.33o ) and occlusal plane angles (10.77o ) in group 2 were statistically higher than those found in group 1 (FMA - 27.57o ); occlusal plane angle - 6.23o ). The mean value for FMIA angle (62.73o ) in group 1 was statistically higher when compared to group 2 (57,80°). According to these results, one can conclude that cephalometric tracing of porion points (either anatomic or metallic) alter the values for FMA, FMIA, and occlusal plane angles, thus resulting in different treatment plans
