Anchorage In Orthodontics: Resistance to Tooth Displacement

Anchorage in its orthodontic application is defined as resistance to unwanted tooth movement.Almost since its inception references to the term anchorage have been found in the orthodontic literature. In the seventh edition of his book, Angle devoted a chapter to this subject. He stated that there were many means for obtaining anchorage or resistance, including the tooth themselves and sources external to the teeth. An important aspect of treatment is maximizing the tooth movement that is desired, while minimizing undesirable side effects in planning orthodontic therapy, it is simply not possible to consider only the teeth whose movement is desired, reciprocal effects throughout the dental arches must be carefully analyzed, evaluated & controlled.Thus anchorage is one of the major problems in orthodontics and is an important study.
