Disjunção palatina com a utilização de expansor maxilar diferencial: Relato de caso

Abstract

Maxillary expanders are orthodontic appliances used to correct posterior crossbite problems and narrowing of the upper dental arch. Among the various types of expanders, the differential maxillary expander is an option indicated for patients with posterior crossbite or maxillary narrowing, as it allows asymmetrical expansion of the maxilla in a more controlled and comfortable way for the patient. The objective of this work is to document and describe a clinical case in which the appliance was used as part of a patient's orthodontic treatment. In addition to contributing to scientific knowledge in the area of orthodontics and helping professionals to make clinical decisions. This work describes a clinical case in which the differential maxillary expander was used as part of the orthodontic treatment of a patient, in addition to performing a descriptive and analytical bibliographical review, searching for articles in the Pubmed and Bireme/BVS databases between 2013 and 2023 with the descriptors "Differential Maxillary Expander". In this way, 16 articles were found in Pubmed and 19 articles in Bireme/BVS, of which 10 were selected for the review, following the inclusion criteria of articles published in the last 10 years, literature reviews, meta-analyses and case reports with good bibliographic contextualization, and exclusion of articles that were not aligned with the objectives of the work and publication duplicity. The performed analyzes highlight the importance of careful choice of expander type during rapid maxillary expansion and reinforce the need for further research in this area to better understand the long-term effects of rapid maxillary expansion and the optimal choice of expander for each patient. With this information, orthodontists can make more informed and personalized decisions regarding the choice of expander type during rapid maxillary expansion, aiming to obtain better results for their patients.
