Early Treatment of Anterior Crossbite with Eruption Guidance Appliance: A Case Report

Abstract

The purpose of this investigation was to show how to manage an anterior crossbite in early mixed dentition with an eruption guidance appliance (EGA). The analyzed clinical case reported an anterior crossbite, a bimaxillary retrusion tendency, and a horizontal growth pattern. The anterior crossbite was an unfavorable occlusal condition that could lead to a class III malocclusion growth pattern. An early treatment approach was suggested to reach a correct sagittal jaw relationship. Hence, the selected approach acted on the dentoalveolar sector, aiming to have effects on the posterior vertical dimension and to improve the sagittal jaw’s relation. An EGA was selected to treat the patient in early mixed dentition. After 7 months of therapy with night-time use, the dental malocclusion was completely resolved. The patient continued to be treated with the same device, used as active retention. With the EGA treatment, the erupting forces, rather than the active forces, were used to resolve the dental malocclusion. This approach allowed a low compliance requirement and had a minimum psychosocial and psychological impact on the patient. The early treatment was essential to give a functional occlusion and a good balance of the soft perioral tissues and muscles.

Intercepting of Class III Malocclusion with a Novel Mechanism Built on the Orthopaedic Appliance: A Case Report

“…Interception of Class III malocclusion can lead to soft- and hard-tissue improvements. [ 13 , 14 , 15 , 16 ]. The negative anterior overjet has an unfavourable effect on the growth pattern because it could cause worse skeletal problems [ 17 , 18 ].…”

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.…”

Esta maloclusión si no es interrumpida lo antes posible, tiene un efecto desfavorable sobre el patrón de crecimiento, porque puede conducir al desarrollo de un problema esquelético 1 . En esta condición, la mandíbula ralentiza el crecimiento del maxilar superior y su posición avanzada favorece el crecimiento hacia adelante 11 .…”
