Abstract

Background: This case report discusses the orthodontic treatment of a 13-year-old Boy who exhibited a skeletal Class III malocclusion, anterior crossbite, and a concave facial profile. The treatment plan included the use of rapid maxillary expansion (RME) for 15-20 days and a facemask over a period of six months. The RME appliance was utilised to widen the maxillary arch and open circummaxillary sutures, which play an important role in the expansion of the maxilla; by the late mixed dentition period, the maxilla fuses to other bones.so rapid maxillary expansion appliance is necessary. Creating the necessary space to correct the anterior crossbite and to overcome the problem of the foot and shoe principle (Shoe Refers to the widened maxilla after RME, or It’s like expanding the shoe to accommodate a larger foot. Foot Represents the mandible. Just as a foot moves forward when placed in a wider shoe, the mandibular arch responds by posturing forward after the maxilla is widened). It will help in improving the sagittal relationship of jaws and improve the occlusion. Simultaneously, the facemask provided protraction forces to guide the maxilla forward, addressing the skeletal discrepancy. Significant improvements were observed in the patient’s facial profile, with a noticeable reduction in facial concavity. The anterior crossbite was successfully corrected, resulting in a harmonious occlusion. This case highlights the effectiveness of combining RME and facemask therapy in managing complex skeletal malocclusions in growing patients.
