  • Patent number: 10391265
    Abstract: Disclosed are applicators and methods injecting of a liquid anesthetic into a dental patient with no or minimal pain. In accordance with one embodiment the applicator is for intraligamentary injection and includes an elongated, thin member having an open distal free formed of a resilient and somewhat conformable material suitable for producing a substantially fluid-tight interface with the anatomic structures at the gingival sulcus to inject the anesthetic therein. In another embodiment the applicator includes a flexible skirt surrounding a sharpened cannula, with the cannula being movable with respect to the skirt. The skirt is arranged to receive the anesthetic to anesthetize the gum, whereupon the cannula can then pierce the gum to inject the anesthetic into the underlying anatomic structure.

  • Patent number: 9687606
    Abstract: Disclosed are applicators and methods for injecting a liquid, such as anesthetic, into a patient with no or minimal pain. The applicator includes a coupling and a blade rotatably mounted on the coupling. The coupling is arranged to receive a cartridge in which a cannula is mounted such that the cannula extends through a proximal channel of the coupling and into a distal channel of the blade. The coupling is further arranged to secure the applicator to a source of liquid such that the liquid can be selectively introduced into and through the cannula into the tissue of the patient. The blade is thin enough for atraumatic insertion into a gingival sulcus of the patient.

  • Patent number: 9055985
    Abstract: A dental implant assembly comprises an implant body adapted for securement within a bore in a jaw bone of a patient. The implant body has a portion with an external thread for engaging the bore. An abutment has a top portion and a bottom portion. The top portion of the abutment is adapted to secure a prosthetic component. The bottom portion of the abutment is attachable to the implant body and adapted to be positioned below a gumline of the patient, the abutment formed of a first material. A cover is sized and shaped to cover the bottom portion of the abutment and adapted to be positioned below the gum line, without covering the top portion of the abutment. The cover is formed from a second material having a different color from the first material.

  • Patent number: 8696720
    Abstract: A dental implant assembly comprises an elongated tubular body adapted for securement within a bore in a jaw bone of a patient. The body has an expandable bottom portion. The expandable bottom portion has an outer thread on an outer surface. The outer thread has a major diameter that gradually increases from a first major diameter near a bottom end of the body to a second major diameter near a top end of the bottom portion. The top end of the bottom portion is located between the bottom top ends of the body. An expander at least partially extends into the bottom end of the tubular body. The expander is configured to be advanced from a first position in which the bottom portion of the body is not expanded to a second position in which the expander forces the bottom portion of the body to expand.

  • Publication number: 20120058451
    Abstract: A method comprises attaching an abutment to an implant body so as to form a seal and cover the implant body, the implant body having a top portion with an external tapered surface and a bottom portion secured within a jaw bone of a patient. The abutment has a top portion adapted to secure a prosthetic component and a bottom portion adapted to be positioned below a gumline of the patient. The bottom portion of the abutment is shaped to attach to and fit over the implant body. The bottom portion of the abutment has a cavity with an internal tapered surface. The internal tapered surface of the abutment and the external tapered surface of the implant body form a Morse taper.

  • Publication number: 20060194171
    Abstract: A bi-polar implant system for use in a patient's jawbone includes an undersized drill shaped cavity formed in a patient's jawbone for receiving a bi-polar implant assembly. A proximal tapered portion is positioned at a proximal end of the bi-polar implant assembly. An expandable skirt portion adjacent to the proximal tapered portion forms a distal end of the bi-polar implant assembly, where the expandable skirt portion includes a plurality of moveable bone anchor segments. A draw screw has a threaded shank portion positioned to cooperate with an expansion nut. Rotation of the draw screw draws the expansion nut upwards into the expandable skirt portion for forcing the movable bone anchor segments into locking engagement with the jawbone. The proximal tapered portion and the expandable skirt portion exhibit an hourglass shape for providing double compaction on the jawbone within the drill shaped cavity for stabilizing the bi-polar implant assembly.
