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

Abstract

An anterior crossbite can be functional, when there is a precontact that generates a mandibular protrusion, or skeletal, a characteristic and early sign of a Class III. An anterior crossbite, both functional and skeletal, if not treated, can lead to a sharp worsening of the malocclusion, causing psychosocial and functional inconveniences. The use of eruption guide appliances (EGA) with different thicknesses can approach this problem very effectively and quickly. In addition, the usability of the device allows to get an excellent collaboration from the patient.
