Patients with class II deep bite malocclusion and hypodivergent skeletal typology represent complex and prolonged cases of treatment due to their muscular characteristics. The etiology of the class II deep bite is multifactorial: environmental and/or genetic factors represent an important part in the establishment of class II deep bite. However, there is a close connection between three class II factors and the adaptation of mandible and occlusal function. These factors are lack of vertical

According to Tanaka and Sato, there is a relationship between the inclination of the maxillary posterior occlusal plane and the mandibular position, consistent with the etiology of different dento-skeletal structures. The occlusal plane is more tilted in patients with class II and more flat in patients with class III than in individuals with class I occlusions. Patients and methods: Two male teenagers were treated with MEAW therapy, and both treatments lasted 24 months. Results: The MEAW therapy appropriately corrected the class II deep bite over a period of 24 months, achieving a good occlusal, functional, and esthetic result. Conclusions: The MEAW therapy proved to be effective in the treatment of class II deep bite malocclusion, in growing patients.
