Abstract

Introduction: Anterior open bite is the lack of vertical contact or negative overbite between the anterior teeth of the upper and lower arches when the posterior teeth are in occlusion. Its etiology is multifactorial, including heredity, oral habits, unfavorable growth patterns, and increased lymphatic tissue along with mouth breathing and functional oral matrices. The characteristics of individuals with anterior open bite include excessive gonial, mandibular, and occlusal plane angles, mandibular small body, and ramus increased lower anterior facial height, decreased upper anterior facial height, retrusive jaw, Class II tendency, divergent cephalometric planes, lingual position, and inadequate lip seal. Objective: To carry out a concise systematic review of multi-segmented maxillary ortho-surgical treatment in class II patients with maxillary protrusion and open bite. Methods: Experimental and clinical studies (case reports, retrospective, prospective and randomized) with qualitative and/or quantitative analysis were included, following the rules of the systematic review-PRISMA. A total of 289 articles were initially found and, after selection, 17 articles were used to compose this study. Results and conclusion: Significant improvement in anterior occlusion can be expected in most patients when maxillary or mandibular surgery is used for Class II open bite correction. However, there will be individual patients in whom there will be considerable post-treatment changes in the anteroposterior and vertical dimensions. Although individual morphology needs to be taken into account, it appears that both short-term and long-term stability are likely to be greater after Le Fort I surgery compared to bilateral sagittal split osteotomy.
