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, “Can 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. This 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:
After this lecture, attendees will be able to:
Understand the biological mechanism of accelerated tooth movement.
Identify the external aids used to date to accelerate tooth movement.
Evaluate the clinical significance of external aids to accelerate tooth movement and whether these methods can cause any harm to dental structures.
