Correção da má oclusão mordida cruzada anterior com o aparelho ortodôntico plano inclinado

Abstract

Aim: To evaluate the prevalence of anterior crossbite and assess the effectiveness of the Inclined Plane orthodontic appliance in correcting this malocclusion. Method: A clinical examination was conducted on 362 children aged 3 to 8 years, in primary or mixed dentition, from 4 public and 4 private schools. Interceptive orthodontic treatment was performed on those diagnosed with anterior crossbite. Results: The prevalence of anterior crossbite was 1.38%, characterizing 5 of the 362 children evaluated, 60% male and 40% female. One child had a dental anterior crossbite, another had a skeletal anterior crossbite, and 3 had a functional anterior crossbite. Only two accepted treatment, one from a public school and one from a private school, with an average duration of 4.5 weeks. Conclusion: The prevalence of anterior crossbite was 1.38%. The inclined plane proved to be viable and effective in correcting anterior crossbite. It is an orthodontic option in patients with deciduous or mixed dentition, providing greater dentoskeletal development. However, this method can cause discomfort when eating and difficulty speaking in the first few days and must be correctly indicated and its execution technique strictly followed.
