Abstract

Anchorage has been a strong content in the Excellency of the orthodontic treatment. The anchorage conservation was a difficult problem until the early 1900s. The introduction of the mini-screws followed by the skeletal anchorage system and the recent introduction of extra alveolar Bone Screw (EBS) has overcome this problem. The introduction of EBS has also changed the concept of treatment planning by converting borderline surgical cases to non-surgical cases. This is a review article providing an overview of the infra-zygomatic crest (IZC)/ buccal shelf (BS) screws in its application into the field of Orthodontics.
