What are the primary types of anchorage used in orthodontics?

The primary types of anchorage used in orthodontics include intraoral, extraoral, and absolute anchorage because they effectively categorize the different methods by which force can be applied to move teeth.

Intraoral anchorage refers to support that is derived from the structures within the mouth, such as teeth or dental appliances that are placed inside the oral cavity. This can include using neighboring teeth as stable reference points to guide tooth movement.

Extraoral anchorage involves components located outside the mouth, like headgear or facemasks, providing a stable source of anchorage to control the forces during tooth movement while minimizing unwanted movements of other teeth.

Absolute anchorage is a more specialized concept in which teeth or anchorage units are meant to remain completely stationary, effectively allowing for significant movements of adjacent or opposing teeth without any unintended movement of the anchorage itself. This is often achieved using implants or reinforced dental structures.

These different types of anchorage help orthodontists determine the most appropriate method for managing tooth movement and ensuring effective treatment outcomes.
