Abstract
Orthodontic adhesive is cooled below ambient temperature in order to facilitate applying the adhesive to the base of an orthodontic appliance. The adhesive is placed on a carrier and formed into a certain shape on the carrier, and then released from the carrier while cool. In one embodiment, a quantity of adhesive is placed on the base of the appliance, and the appliance is then moved to a cut-off die while the adhesive remains cool and relatively brittle; next, a stream of pressurized air fractures and removes excess adhesive from the appliance base.
