  • Patent number: 9763749
    Abstract: A compressible dental instrument to non-impressively adapt restorative material through compression comprises a handle portion (2), having a docking aperture (4) to interface with a highly compressible foam insert (10) with a docking extrusion and a tip holder (14) having highly compressible tip (16). A user can dock both to compressively adapt composite resin to a tooth's surface by first applying a restorative to a tooth and second applying the compressible portion to the restorative. Applied pressure compresses the tip to non-impressively micro manipulate composite resin.

  • Publication number: 20130316301
    Abstract: A dental tweezers with plastic tweezers main body is disclosed. A weight cavity is disposed on both tweezers arms of the main body. Weight arms of a metal weight are inserted into the weight cavities. A weight seat holds the metal weight in place on the tweezers main body. The metal weight makes the dental tweezers feel heavier and more substantial. After the dental tweezers have been used the metal weight is removed from the main body. The plastic tweezers main body is disposed of and the metal weight is retained for future use in an new plastic tweezers main body. A use indicator of the tweezers main body indicates that the dental tweezers has been used. The use indicator provides easy determination of whether or not the dental tweezers has been previously used.

  • Publication number: 20110151406
    Abstract: Dental forceps for holding dental articulating paper has dual elongated spring arms, moveable toward and away from each other. The spring arms each have a lower handle section, an intermediate section extending from the lower handle section, and an upper section with a cantilevered member extending from the top end of the intermediate section. Clamping support arms extend outward from and perpendicular to the cantilevered member of each of the spring arms. The support arms have jagged surfaces which enhance the paper holding capability of the spring arms. When the spring arms are fully biased away from each other, the support arms are closed and articulating paper is held therebetween. When the lower handle sections of the spring arms are moved together, the support arms open to release the paper.

  • Publication number: 20080090205
    Abstract: A dental dam clamp comprises first and second spaced, opposing jaws and respective first and second tooth engaging portions on the jaws. The first and second tooth engaging portions are positioned in confronting relation to one another and are biased toward one another by a resilient member when the jaws are moved outwardly from a free state defining a first position of the jaws. In one embodiment, first ends of the tooth engaging portions are spaced closer together than the second ends of the tooth engaging portions when the jaws are in the first position. The spacing between the first ends of the tooth engaging portions may be substantially the same as the spacing between the second ends of the tooth engaging portions when the jaws are moved outwardly to a second position. In another embodiment, the tooth engaging portions include friction-increasing surfaces to help secure the clamp to a tooth.

  • Patent number: 6471515
    Abstract: The current invention provides a device for holding dental abutments such as healing caps, healing screws, contoured healing abutments, PME (precision margin esthetics) abutments, PME impression pins, hexed transfer assemblies, straight and angled fixed system components, hexed coping screws or any dental implant parts when the object is being inserted or otherwise located into a patient's mouth. The device is tweezer-like and is designed to hold a dental abutment having a central axis. The device includes a pair of substantially identical members that are joined together at one of the ends and each have a free end. The members are disposed in the V-like configuration with the joined ends interconnected and the free end spaced apart so that when the members are squeezed towards one another, the free ends are brought into contact. Each of the members has a handle portion including the joined end, and an offset gripping portion.

  • Patent number: 6322363
    Abstract: A tweezer-like dental pliers having a pair of elongated, flat and generally parallel handles with connected first ends, spaced-apart central portions, and second ends with normally closed gripping tips. The second ends are bent at an acute angle, preferably about 70 degrees, with respect to the handles, and a projecting fulcrum contacts the handles adjacent the bend so the gripping tips can be separated by squeezing the handle central portions together. A screw engaged between the handle central portions adjustably limits separation of the central portions to control gripping pressure of the normally closed tips.

  • Patent number: 4594069
    Abstract: A dental crown (cap) remover with unique crown separating and removing means is adaptable to a wide variety of crown sizes and configurations and does not place compressive or axial forces on the underlying tooth or its supporting processes (alvoelar bone and periodontal fibers). The crown remover has a grasping and tightening mechanism that allows the dentist operator to firmly seat the crown remover on the crown to be removed, and has an elliptical separating mechanism that inserts in a precut groove in the crown and forces separation of the halves of the crown, increasing the circumferential dimension breaking the cementing medium and loosening the crown from the underlying tooth, providing for ease of separation of the crown from the tooth.
