This paper describes the SAO®, Sistema de Apoio Ósseo para Mecânica Ortodôntica (Skeletal Supported System for Orthodontic Mechanics), a new approach for anchorage by means of mini-plates. After the description of the system, treatment protocols for skeletal openbite cases are presented. The use of cantilevers and different spring configurations attached directly in the tubes of the anchorage system allows various approaches for vertical and sagittal discrepancies.
