Miniscrew implant-supported Frog® appliance for maxillary molar distalization

Abstract Various appliances have been used for the correction of Class II malocclusion. The majority of these appliances depend on patient compliance for a successful treatment outcome. An 11-year-old girl was referred to our clinic for orthodontic treatment. She had a mild skeletal Class II malocclusion with Class II molar and canine relationship on both sides. The treatment plan included bilateral distalization of the maxillary first molars using a miniscrew implant-supported frog appliance along with comprehensive orthodontics. Successful correction of Class II malocclusion was achieved with the use of a relatively new intraoral distalization appliance–the Frog ® Appliance. Proclination of maxillary incisors was minimal due to the use of miniscrew implants. This article presents an effective, noninvasive, and compliance-free intraoral distalization appliance for achieving maxillary molar distalization.
