Resumen

RAVELO, Víctor; DE-MORAES, Márcio  y  OLATE, Sergio. Transverse, Vertical and Sagittal Relationship in Subjects with Facial Deformity Candidates for Orthognathic Surgery. Int. J. Odontostomat. [online]. 2020, vol.14, n.4, pp.664-669. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2020000400664.

The aim of this study is to evaluate the relationship between sagittal skeletal class and transverse or vertical conditions in subjects with facial deformity without presence of facial asymmetry; A comparative study was conducted between the results of the cephalometric analysis of the sagittal, transverse and vertical skeletal class in 115 subjects with indications for orthognathic surgery. The Steiner cephalometric analysis in the sagittal direction was used to determine the facial skeletal class and the Ricketts cephalometric analysis in the sagittal analysis. At the transverse level it was determined the facial transverse dimension, maxillary transverse dimension and mandibular transverse dimension. At a vertical level it is determined the occlusal vertical dimension and total vertical dimension. When comparing cross-sectional and vertical measurements between female and male subjects, it was observed that male subjects presented greater dimensions than female subjects (p=0.0001). Class III subjects present greater facial transverse dimension (p=0.0002) and mandibular transverse dimension (p=0.001) than class II subjects. Also, it was observed that class III subjects had a greater total vertical dimension (p=0.002) than class II subjects; It is possible to conclude that there are facial characteristics transverse and vertical that can be related with the sagittal position of the maxillo-mandibular structures.
