BLANCO MEDEROS, Félix Manuel et al. Behavior of dental occlusion in patients undergoing orthognathic surgery. Rev.Med.Electrón. [online]. 2017, vol.39, n.2, pp. 200-211. ISSN 1684-1824.

Introduction: the orthognatic surgery corrects the alterations of the skeletal component in dentomaxillafacial anomalies. These deformations cause deficient relations of the maxillary bones, affecting the dental occlusion and its functions. Objective: to identify dental occlusion behavior in patients undergoing orthognatic surgery. Materials and methods: an observational, descriptive study was carried out with the objective of identifying oclussal characteristics in patients who underwent orthognatic surgery. The used variables were: molars relation, guides of lateral functioning, kinds of chewing, occlusive interferences in protrusion movements and in movements of laterality. Results: patients were found with molars relation of mesiooclussion, which is an indication of recidivism in the achieved neutroclussion. The surgical intervention with higher incidence was mandibular retro positioning accompanied by centralization. There it was a great improvement of the chewing function. Most of the patients were free of oclussal interferences. Conclusions: the assessed patients were in the age-groups from 24 to 38 years, and female sex predominated with 60.5 %. 13.2 % of the subjects had mesiocclusion, with higher incidence in the cases surgically treated with jaw retroposition and centralization.  The canine tooth function in the lateral movements predominated. Most of the patients were free from occlusive interferences, being 71.1 % of the studied patients.
