AS17B37A - Skeletal Anchors and Expedited Tooth Movement: Coming a Full Circle?

Apr 24, 2017 8:00am ‐ Apr 24, 2017 8:30am


Both skeletal anchors (SA) and expedited tooth movement (ETM) are at the forefront of innovations in clinical orthodontics. While intraalveolar SA have been used extensively, one major advantage of extraalveolar SA is the possibility of enmasse movements without the anchor interfering and being in the path of tooth movement. Failure rates of SA, the ability to provide anchorage for different dental and skeletal orthodontic applications vary widely between intra and extra alveolar SA. Similarly, there is conflicting information on efficacy of expedited tooth movement. The central question that we need to answers is whether there is adequate clinical evidence to support methods to ETM.

Learning Objectives:

  • Identify the key differences between intraalveolar and extraalveolar SA.
  • Identify factors in the bone physiology that relate to failure of intraalveolar and extraalveolar SA and rate of tooth movement.
  • Assist clinicians in understanding choices of SA.
