Open Bite Treatment with Combined Aligners and Myofunctional Appliances: A Case Report

This case report describes an 18-year-old female patient with a skeletal class I pattern, mandibular asymmetry, a molar class III on the right side, a molar class II on the left side, and an anterior open bite (AOB). Treatment of AOB is often difficult for orthodontists and a multidisciplinary approach is sometimes required to rehabilitate the correct function and posture of the tongue. In this case the AOB was treated using the Nuvola (R) OP System: a treatment system that combines orthodontic aligners and a myofunctional elastodontic device called Freedom. An upper molar intrusion with miniscrews was performed during the first phase of the treatment programme, and then the aligner treatment began. The Nuvola (R) OP System 's aligners are characterized by lingual pins that guide the tongue to the palatal spot position and take advantage of tongue function. The patient was instructed to wear the Freedom device for 30 min a day and to clench every 3 s with closed lips while wearing the aligners. These exercises improve the fitting of the aligners, improve the tongue's posture, and take advantage of the masticatory forces to resolve the malocclusion. The patient was successfully treated, thus demonstrating that the Nuvola (R) OP System is a valid alternative for the treatment of AOB.
