Tratamento do padrão II esquelético e apinhamento associado com mantenedores de espaço, aparelho fixo e extrabucal: relato de caso clínico

Abstract

Introduction: Supervision, in the evolution of the mixed dentition, is important to enable interventions that can be implemented from the point of view of preventive orthodontics, thus avoiding the possible extraction of permanent teethduring the corrective phase of orthodontic treatment. Objective: To report a clinical case of orthodontic treatment without extraction of permanent teeth with space maintainers, fixed and extraoral orthodontic appliances. Case report: Patient G.B.V., 6 years old, female, in 2006, sought dental care at a private clinic in the city of Maceió-AL. Initially, only the making of study models in plaster and panoramic radiographic examination of the jaws were requested to monitor the evolution of the dentition, which happened when the following circumstances occurred: exfoliation of the deciduous tooth; permanent tooth eruption; or else every 6 months. 5 years later, in 2011, a new radiographic examination was performed for the installation of a lingual arch and transpalatal bar. After 1 year of use of space maintainers, through a preventive approach, the preparation of type 2 orthodontic documentation was requested to initiate the corrective phase of treatment. Thus, the use of fixed and head gear of the “Kloehn” type was indicated. In July 2015, with 3 years of the corrective phase, the final documentation was requested to finalize and record the treatment, as well as upper and lower retainers were made. Conclusion: Orthodontic treatment, well executed and associated with preventive and corrective measures, allowed achieving the main idealized objective, that is, treating a patient orthodontically without the need to extract permanent teeth.
