However, limitations in these aspects often result in the referral of patients with inadequate occlusal conditions, which can compromise the predictability of outcomes. The objective of this study was to evaluate the quality of pre-surgical orthodontic preparation in patients admitted to an Oral and Maxillofacial Surgery and Traumatology service. All patients underwent intraoral scanning, with STL files corrected using NetFab software and 3D-printed to produce pre-surgical resin models. The models were manually placed into final occlusion, and variables indicative of stable occlusion were assessed, such as midline alignment, sagittal position of canines in Class I, normal overbite and overjet, aligned arches, and absence of crossbite or cant. Among the analyzed models, 46% demonstrated the absence of stable intercuspation, presenting at least one flaw, such as cant (42.8%), posterior crossbite (28.6%), deep overbite (25%), Class II canines (20%), pronounced overjet (14.3%), misaligned midlines (10.7%), triangular or quadrangular arch forms (8.6%), and misaligned arches (7%). In conclusion, a significant proportion of patients were referred for orthognathic surgery with inadequate orthodontic preparation and identifiable flaws, which may jeopardize surgical success and prolong treatment duration.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Cirurgia OrtognáticaTécnicas de Movimentação DentáriaMá OclusãoAvaliação da qualidade do preparo ortodôntico de pacientes admitidos para cirurgia ortognática em um hospital de CTBMFAssessment of the quality of orthodontic preparation in patients referred for orthognathic surgery at a maxillofacial surgery centerbachelorThesis
