Highlights
Crossbites are frequent malocclusions
in dental routine and their
management by pediatric dentistry
extends his/her field of work.
Based on the correct diagnosis of
crossbites, the clinician can manage
more effective and less timeconsuming treatments, leading to
patient satisfaction and increasing their
self-esteem.
This work allows the pediatric dentist
to be familiarized with the smart
treatment of combined posterior and
anterior crossbite and encourages
him/her to treat them.
Abstract
Anterior and posterior crossbites are malocclusions in the sagittal and transversal dimensions, respectively. As self-correction is rare in these alterations, early interception is recommended to allow normal occlusion and facial development. This case report aimed to discuss the treatment of an eight-year-old boy with an increased inferior facial third, who was submitted for rapid maxillary expansion with a modified bonded appliance to solve both transversal and anteroposterior deficiencies. The correctionof both malocclusions was achieved within 21 days. The advantages of this procedure were to gain space in both arches, enlarge the maxillary arch, and improve nasal breathing. The interceptive therapy, as well as a well-planned appliance, proved to be effective and important for retrieving the patient ́s normal condition and quality of life.
