Correction of Anterior Crossbite, Using Removable Appliances in Mixed Dentition: 5-Year Follow-Up

The anterior crossbite (ACB) is a malocclusion where the upper anterior teeth are occluding lingually with respect to the lower anterior teeth. Moyers describes anterior crossbites as dental malocclusions resulting from abnormal axial inclinations of the anterior teeth. This type of malocclusion can be dental, functional or skeletal and can occur in the primary, mixed and second dentition. Diagnosis is made using diagnostic aids. While the treatment was carried out through interceptive orthodontics, with the use of different removable appliances. The objective of the study is to present the diagnosis and treatment for 5 years with the use of removable appliances. The results were favorable, being able to uncross the bite in 4 months, it was maintained throughout the dental replacement. One of the conclusions reached is that the treatment time is slightly longer since the use of preventive and interceptive orthodontics takes more time because these treatments are performed during the growth of the patients.
