What are the types of anchorage used in orthodontics?

The identification of the types of anchorage used in orthodontics as intraoral, extraoral, and skeletal is grounded in the fundamental principles of orthodontic treatment. Intraoral anchorage refers to methods utilizing structures within the mouth, such as teeth, to provide the necessary resistance against unwanted tooth movement during orthodontic procedures. Extraoral anchorage typically involves the use of appliances that are positioned outside the mouth, such as headgear, which helps to control the movement of teeth by anchoring them to structures like the skull or neck. Skeletal anchorage is a modern approach that incorporates implants or other fixed devices anchored to the bone, allowing for greater stability and predictable movement of teeth.

The choice incorporates a well-recognized categorization crucial for understanding how forces are applied in orthodontics to achieve desired tooth positioning while minimizing unwanted movements. Understanding these types of anchorage helps practitioners decide on the most effective means to achieve ideal dental outcomes in their patients.

Other options present categories that are not typically used in a classification system for anchorage in orthodontics, thereby making them less relevant in this context.
