ABSTRACT:
A dental undercut application device for producing an undercut on the surface of a tooth for securing a dental appliance. The application device contains an undercut or applique with a curved front side for engagement with the surface of the tooth and a stem on the back side attached to a locator tab. The locator tab can be grasped when applying the adhesive to the front side of the undercut and for locating the undercut on the surface of the tooth while the adhesive cures. When the undercut is secured to the tooth, the stem is cut and the tab removed. The back side of the undercut may then be smoothed to match the contour of the tooth. Clasps on removable orthodontic appliances or removable partial dentures engage with the undercut to retain the dental appliance or denture in the patient's mouth.
