Correction of Single-Tooth Crossbite in Children: A Report of Three Cases

Single-tooth anterior dental crossbite is a commonly observed malocclusion in the mixed dentition of children. Early intervention is crucial since malocclusion does not correct itself and can contribute to enamel wear, periodontal disease, and disturbances in temporomandibular joint function. Several treatment methods have been proposed to correct it, including removable appliances and uncomplicated interceptive techniques. This case report shows three pediatric patients diagnosed with single-tooth anterior crossbite. In one case, the crossbite was successfully treated with a Hawley's appliance featuring a Z-spring and a posterior bite plane in just a few weeks. In the remaining two cases, tongue blade therapy was used as a minimally invasive treatment. In one case, crossbite correction was achieved following the performance of a diode laser-assisted frenectomy, which was necessary because a thick labial frenum was obstructing the proper alignment of the teeth.
