ABSTRACT:
A device for manipulating dental restorations, such as thin, ceramic tooth veneer of the type used in cosmetic bonding to teeth comprises an elongated, pencil-like handle structure having a tip which is releasably attachable to a surface of a veneer, affording convenient means for manipulating the veneer, as for example when bonding the veneer to a patient's tooth. A basic embodiment of the device includes a thin, small flexible circular plate attached transversely to one end of the pencil-like structure and forming the tip of the device. The outer tranverse of the tip plate, which may be flat or concave, is coated with a tacky substance providing sufficient adherence to the surface of a ceramic veneer to permit the veneer to be picked up when the plate is gently placed in contact with the surface of the veneer. The adhesion force of the tacky substance is sufficiently small to permit the tip to be disengaged from the veneer with a slight pulling force, when desired. Another embodiment of the device employs a plastically deformable tip made of a resilient, lenticular shaped body with a generally flat, adhesive-coated lower surface. The tip is adapted to conform to the irregular biting surface of a crown or bridge. Upon placement of the crown or bridge in the mouth of the patient, the handle may at the dentist's option be pulled out of the tip, the latter remaining to serve as a bite plate or seating fixture while the restoration is being bonded to existing teeth.
