Disjunção maxilar na ortodontia infantil: uma revisão de literatura

Abstract

INTRODUCTION: Preventive and interceptive orthodontics aim to prevent and address early alterations in dentofacial development, such as malocclusion, which can impact aesthetics, function, and quality of life. Conditions like crossbite and palatal constriction can be corrected with maxillary expanders such as Hyrax and Haas, promoting palatal expansion and achieving functional and aesthetic balance. Early intervention is essential to ensure harmonious craniofacial development and prevent future complications. OBJECTIVES: To review the clinical approaches to maxillary disjunction in pediatric orthodontics, highlighting its indications, advantages, and disadvantages, aiming to establish a solid foundation for clinical practice and improve decision-making to enhance the quality of life of pediatric patients. METHODOLOGY: This literature review focuses on early treatment of posterior crossbite using maxillary expanders, analyzing studies from 2007 to 2023 found in Google Scholar, Scielo, and PubMED databases. Articles addressing maxillary disjunction in mixed dentition were included, excluding surgical interventions and adult cases. The analysis was based on rigorous selection criteria and specific keywords related to the topic. RESULTS: The results were obtained from Table 01, which analyzed 10 articles. FINAL CONSIDERATIONS: The review of clinical approaches to maxillary disjunction in pediatric orthodontics highlights the effectiveness of Haas and Hyrax expanders, with specific advantages for each case. Early diagnosis, individualized planning, and continuous follow-up with appropriate retention are essential to prevent relapse and improve quality of life.
