Abstract
An active dental attachment. Specifically, an attachment device for interacting with a polymeric shell dental appliance is described. The attachment device includes an anchoring attachment body. A bonding surface is coupled to the anchoring attachment body, wherein the bonding surface is configured for anchoring the anchoring attachment body to a dental feature of a patient's dentition. A force-applying active mechanism is coupled to the anchoring attachment body. A polymeric shell dental appliance contact region is coupled to the force-applying active mechanism. The polymeric shell dental appliance contact region is configured to contact the force-applying active mechanism and apply a force generated by the force-applying active mechanism between the dental feature and the polymeric shell dental appliance when the polymeric shell dental appliance engages the force-applying active mechanism.
