  • Patent number: 8740616
    Abstract: A dental implant system includes a base member that is adapted to be embedded within a patient's jawbone at a treatment site. The base member has a generally flat top defining an outer periphery, a buccal side, a lingual side, a bottom, and a central opening. The lingual side or the buccal side is longer than the other. The base member is configured to be positioned within a recess in the patient's jawbone. An implant screw includes a head and a threaded end. The threaded end is adapted to pass through the central opening of the base member and into the patient's jawbone, and the head is adapted to be seated within the central opening of the base member after the threaded end is screwed into the patient's jawbone. An abutment is configured to be placed onto the top of the base member.

  • Patent number: 7806685
    Abstract: A dental implant system in one embodiment is constructed of a base member that is to be embedded within a patient's jawbone. This base member has a central opening that tapers inward from a top surface to a bottom surface. The system also includes an implant screw haying a head and a threaded end which passes through the central opening of the base member and into the patient's jawbone. The head has a tapered section to seat within the tapered opening of the base member. In this way, the base member is secured to the jawbone while the base member is embedded within the patient's jawbone. A crown is provided to be coupled to the implant screw.

  • Publication number: 20090226857
    Abstract: A tooth implant assembly has a base plate, a base attachment fastener a collar a crown attachment fastener, cylindrical insert, and a tooth crown. The base plate has a central opening and a coronal surface. The base attachment fastener is adapted for insertion into and engagement with the central opening in the base plate. The base attachment fastener also has a head with a central bore extending longitudinally into the head. The collar has a longitudinal opening with coronal and apical edges. The collar is disposed on the coronal surface of the base plate. The crown attachment fastener has a threaded distal end adapted for threaded engagement with the central bore of the base attachment fastener. The cylindrical insert is disposed within the collar and supported by the coronal edge of the collar. The insert has a longitudinal channel formed therein for carrying the crown attachment fastener. The tooth crown is supported by and attached to the collar.

  • Patent number: 4857676
    Abstract: Method of making insulated conductor wire in which a homogeneous mixture of a dielectric carrier and magnetically permeable particles is sprayed onto the wire to deposit a layer of the mixture on the wire. The layer is then hardened to provide an insulating layer with the particles substantially uniformly dispersed therein.

  • Patent number: 4734997
    Abstract: In a method and apparatus for drying filamentary material, a duct is provided for enclosing a portion of a passline. The duct comprises two parts relatively disposed laterally of the passline. These parts are relatively movable away from one another laterally of the passline to provide a duct open position and towards one another to provide a duct closed postion. First and second guide wheels are provided for guiding the filamentary material along the passline through the duct. The guide wheels are relatively movable along the passline between the duct parts in the duct open position between a first pair of relatively close positions and a second pair of positions at opposite ends of the duct. With the duct in the duct open position and the guide wheels in the first pair of positions, filamentary material is fed over the guide wheels.

  • Patent number: 4708887
    Abstract: In a method and apparatus for coloring polymer-insulated wire, the wire is guided through a solvent reservoir to dissolve surface contaminants and etch the surface of the insulation, and passed between opposed wiping surfaces to wipe surface contaminants from the wire. The wire is then passed through a hot air duct to evaporate solvent remaining on its surface. The dried wire is guided through a solvent-based colorant reservoir to coat it with colorant and passed against a wiping surface to wipe excess colorant from its surface. The coated wire is passed through a hot air duct to evaporate some of the solvent in the colorant, and through a cold air duct to harden an outer surface of the colorant before it passes over a guide wheel. The hardened surface prevents adherence of the colorant to the guide wheel. The coated wire is passed by a spraying device which intermittently sprays solvent-based colorant on the wire to band encode it.

  • Patent number: 4708837
    Abstract: Extrusion apparatus for conductor wire in which a core tube for guiding the wire is controllably movable axially so as to adjust the cross-sectional area of the flow passage for molten polymeric dielectric material moving towards the die orifice. The use of the adjustable core tube minimizes the degree of draw down of the conductor wire.
