Abstract: The success of orthodontic treatment relies upon careful treatment planning, for both desired and unwanted tooth movement. The theory behind anchorage reinforcement will be considered and the current means of anchorage support and creation will be described. Methods by which the orthodontist can reduce anchorage demand and measure anchorage loss will also be discussed.

Clinical relevance: To understand the clinical applications of the theory of unwanted orthodontic tooth movement and be able to give examples of planned means of increasing anchorage and decreasing anchorage demands.
