Lecture up to 0.75 hour

Orthodontics, AGD Subject Code 370

Understanding and controlling anchorage is essential in successful orthodontics. For every active force, there is an equal and opposite reactive force. Techniques utilizing the osseous complex surrounding the teeth can be implemented to control these forces, enabling the desired tooth movement while keeping others from moving. Controlling individual teeth, segments of teeth, and the occlusal planes are essential in order to create a foundation for implant and restorative dentistry to build on. 

With advancements in osseous anchorage such as temporary anchorage devices, osseous plates, and implants, we have control of the dentition like we never have had before. This advancement in conjunction with clear aligner therapy creates the ideal treatment modality to set up an array of restorative cases. 

This lecture will demonstrate types of current skeletal anchorage, effective locations to place them, and how to use them with clear aligners to achieve desired tooth movement in a multitude of pre-restorative orthodontic cases.

Upon completion of this session, the attendees should be able to:

• Determine when a case could benefit from osseous anchorage versus traditional anchorage in order to better produce the desired tooth movement necessary for optimal restorative results.

• Identify the types of osseous anchors and where they should be placed for different case types based on anatomy and desired tooth movement.

• Understand why detailed planning and effective communication between the interdisciplinary team is essential in determining tooth position for an optimal restorative outcome.
