Aligners rely on close adaptation to the tooth shape to impart forces and need a certain level of “grip” to avoid slippage. Engagers provide that additional “grip” on the tooth for the aligners to better deliver tooth movement forces. Engagers also known as “attachments” are small bumps made up of composite material that is commonly placed on the tooth to assist with certain tooth movements. In this video learn more about engagers with step-by step instructions on how to place engagers, how to remove engagers, and helpful tips to placing engagers.
Nicely explained 😊
