Early treatment and the need for interceptive care for the patients with Class III malocclusion has always been a dilemma, it is required to prevents damage to the oral tissues and/or significantly reduces the amount or severity of future orthodontic and surgical interventions. . To overcome the limitations of tooth-borne appliances in this interceptive treatment of Class III malocclusions, Skeletal anchorage system (SAS) or bone-anchored maxillary protraction (BAMP) appliances had been used. Skeletal anchorage yields greater maxillary protraction and reduces undesirable dental effects. SAS appliances offer the potential for more skeletal changes compare to tooth-borne appliances.
