Innovative Protocol for Early Class III Correction with Aligner and Facemask: A Case Report

The purpose of this case report is to describe the treatment of a Class III malocclusion in the primary dentition using maxillary expansion with aligners, in combination with a facemask anchored to buttons or hooks integrated into the aligners.The treatment objectives included correcting anterior and posterior crossbites, achieving maxillary protrusion through maxillary traction, improving mandibular dynamics, and balancing the facial profile.Skeletal and dental changes were evaluated, revealing a significant increase in the SNA angle and harmonization of the anteroposterior relationship according to Wits values.Vertical skeletal characteristics remained stable throughout the treatment.
