Abstract

The purpose of this study was to undertake a proposal of True Horizontal through the point "T" and compare it with the Frankfort and Sella-Nasion planes. The sample was composed of 15 young adults aged 19-24 years, both sexes, from Culiacán, Sinaloa, Mexico. They all had normal occlusion. The lateral skull x-rays were made by placing the patient with reference to the natural head position. FH and SN planes were related to points A,B and Pogonion to set differences between angle and linear measurements. In analyzing the FH plane in respect to True Vertical, there were 8.4° ± 3.0 inclination in FH plane and 11.4° in plane SN. The linear variables to the vertical of each of the planes showed statistical differences VFH-A (p< 0.0166), VSN-A (p< 0.0217 and those values related to point B were observed. A similar behavior was found in variables at point Pg where the values of VFH-Pg with VTH-Pg compared to VSN-Pg with VTH-Pg showed statistical differences, finding that they matched with the clinical characteristics of the studied sample. It is necessary to go deeper into these studies so as to use these lines of references (VNN and HVT) as basis for registers and cephalometric analysis.
