  • Publication number: 20250241729
    Abstract: The invention prescribes a dental tooth elevator for dental use, one embodiment of which exhibits a doubled bladed instrument formed by a U-shaped notch which resists bending for extracted teeth and gum line when embedded to expand and loosen teeth between tooth and bone both mesio-distal (backward) and bucco-lingual (side-to-side) as said elevator is twisted by operator increasing tooth movement while, unlike traditional straight elevators, the flat tipped doubled blades further resists slippage during tooth extraction.

  • Publication number: 20100047740
    Abstract: A dental crown remover has forceps with opposing beaks. Each of the beaks has a flattened base and a notch located at the base. The faces of the notch form an angle of about 90 degrees to one another, and the lower face of the notch intersects the base at about a 50-degree angle. The notch is intersected by a longitudinal cavity having a width less than that of the beak. This structure defines two sharp points where the longitudinal cavity intersects the base of the beak and the lower face, and two stops where the longitudinal cavity intersects the upper face of the notch. When the beaks of the forceps are moved toward closure, the points of each beak are capable of penetrating and holding a crown, providing stable support at least at four points, which support allows twisting and rocking motion to be applied to break the tooth-to-cement bond holding the crown in place.

  • Patent number: 5421721
    Abstract: The invention prescribes forceps for dental use, one embodiment of which exhibits an enclosure for trapping extracted teeth and dental appliances so as to prevent them, when slipping from the grasp of the forceps' beaks, from falling into the mouth or throat of a patient. A second embodiment includes an abutment member lying inward from the beaks against which abutment member an extracted tooth or dental appliance is lodged as occlusions of the beaks forces the tooth or appliance inward from the beak tips.
