Main clinical and surgical outcomes of crossbite treatment: a concise systematic review

Abstract

Introduction: In the crossbite scenario, the prevalence of malocclusion is 56%, with 10% of crossbites in the primary dentition, 11% in the mixed dentition, and 5% in the permanent dentition. The etiology is multifactorial and early diagnosis of crossbite is essential to reduce the risk of dental, alveolar, and skeletal malocclusions. In this sense, malocclusions are a disorder that is increasingly present in the population. Objective: It was to carry out a concise systematic review of the main considerations of crossbite and malocclusions. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from June to September 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total 117 articles were found, and 22 articles were evaluated in full and 13 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 7 studies with a high risk of bias and 43 studies that did not meet GRADE. Early bite correction will provide benefits, restoring the normal redirection of the eruption of permanent teeth, providing correction of asymmetries in condylar positioning, and favoring ideal occlusion. Furthermore, early expansion with a removable expansion plate is a successful method for correcting crossbites and increasing intermolar width in the early phase of mixed dentition. Results remain stable until comprehensive treatment of the permanent dentition begins. Rapid maxillary expansion is a resource of great value to the orthodontist that can be used to treat maxillary transverse deficiencies.
