Minibone plates: The skeletal anchorage system

The skeletal anchorage system (SAS) is a recently developed orthodontic anchorage modality utilizing titanium miniplates and monocortical screws that are temporarily fixed in the maxilla and/or mandible for absolute orthodontic anchorage. The most appropriate application of the SAS is to enable the predictable intrusion and distalization of maxillary and mandibular molars. Therefore, the SAS offers a nonsurgical orthodontic treatment option for skeletal (surgical) malocclusions, as well as a nonextraction treatment approach for some malocclusions characterized by maxillary or mandibular protrusion, and/or anterior crowding.
