The Present and Future of the Skeletal Anchorage System (SAS) Using Miniplates for the Treatment and Management of Jaw Deformities

Abstract

The SAS using miniplates is a most reliable, effective, and predictable modality. We can remodel the dentoalveolar complex beyond the limits of traditional mechanics through tooth movements with SAS mechanics. Additionally, the miniplate can transfer the orthopedic forces directly to the facial skeleton for bone repositioning and growth modification. Patients with jaw deformities have various complicated dentoalveolar problems according to the degree of skeletal discrepancies. Since the emergence of SAS, comprehensive orthodontic treatment plans have become more extensive and complex than traditional orthodontics, while surgical plans have become simpler and less invasive for patients. Nowadays, non-extraction and non-surgical treatment options are available through SAS for molar intrusion and/or distalization. Additionally, SAS makes it possible to reduce total treatment time and to correct minor surgical inaccuracies and relapse tendencies after orthognathic surgery. Therefore, the application of SAS or other miniplate anchorage devices can improve the quality of surgical orthodontics.
