Infra zygomatic crest (IZC) and mandibular buccal shelf (MBS) bone screws: A comprehensive updated review

Abstract

The definition of anchorage is the opposition a body exhibits to being displaced. In orthodontics, the body is used to simulate a tooth, and forces that can be either light and continuous or heavy and intermittent are used to propel it around. When natural tooth motions are to be performed in greater amounts, they must be fastened against an anchor that, if feasible, is fairly enduring. This is when anchoring is required in orthodontics.
