Myofunctional Treatment of Anterior Crossbite in a Growing Patient

Abstract

The purpose of this case report is to add another means of treatment for the anterior crossbite malocclusion in early mixed dentition. The selected functional device is an eruption guidance appliance (EGA). The analysed patient had a functional anterior crossbite, a mandibular protrusion tendency, and a normodivergent growth pattern. The early treatment was suggested to correct the malocclusion and avoid unfavourable occlusal conditions that could end in a class III malocclusion growth pattern. After 18 months of treatment, with night-time use, the malocclusion was completely resolved. This therapy strategy allowed the correction of the sagittal jaws’ relationship and maximum control of the vertical dimension. After 2 years of follow-up, the results were preserved. The peculiarity of this kind of intraoral orthodontic tools is the use of the erupting forces rather than the active forces. This early treatment of anterior crossbites with EGA may be considered an effective treatment approach for achieving good functional and aesthetic results.

The Treatment of the Anterior Crossbit using an Eruption Guide Appliance with Different Thicknesses: Case Report

“…The dental eruption control allows to modify the mandibular plane inclination and in accordance with Moss' studies of 1999 to restore the ideal inclination for a given patient depending to the growth pattern. Only a few studies have been carried out on the early treatment of anterior crossbite with a myofunctional approach using EGA [16][17]. In these studies, it stands out the enormous effectiveness of this approach, the enormous speed of resolution of the case, and especially the ease of application of the device compared to more bulky devices used for the same treatment.…”
