AS22B06 - Should We Use External Aids to Accelerate Orthodontic Tooth Movement?

May 21, 2022 11:10am ‐ May 21, 2022 11:40am

Credits: None available.


The only way to accelerate orthodontic tooth movement is to accelerate bone resorption via biological response from the periodontal ligament in response to mechanical loading. In fact the question to be asked is, β€œCan we accelerate bone resorption?” Multiple methods, including drugs and external stimuli were tested over the years. Some methods were promoted by companies usually with little or no evidence. The lecture will address all available methods utilized to accelerate orthodontic tooth movement, discussing results of experimental studies, their clinical significance and whether these methods can cause any harm to dental structures.

Learning Objectives:

  • Decide if you should use external aids to accelerate orthodontic tooth movement.
  • Identify whether or not the external aids are harmful to dental structures.
  • Evaluate whether the external aids make clinically significant difference in moving teeth.
