Treatment of a Class II Division 1 malocclusion with the combination of a myofunctional trainer and fixed appliances

This case report describes the combined use of a myofunctional Trainer for Braces and fixed appliances to treat a 10-year-old girl with a Class II Division 1 malocclusion that featured severe maxillary incisor protrusion, a large overjet, and a V-shaped maxillary arch. She had a convex profile with an underdeveloped mandible. The superiority of myofunctional training in the case was to eliminate mouth breathing and lip sucking habits, train the oral musculature, stimulate mandibular growth, and make braces work more efficiently. The post-treatment facial photographs show improvement in the facial profile. Proper occlusion and facial balance were created, which were quite stable as demonstrated by the patient's 4-year follow-up records.
