  • Publication number: 20090065376
    Abstract: A medical implant package including a vial and a cap connected by a hinge. The vial includes a cavity for housing at least a portion of a dental implant. To access the implant, the cap is rotated about the hinge from a closed position to an open position. The cap defines a second cavity, separate from the vial cavity, sized to contain a healing screw. In one embodiment, the cap includes two portions connected by a living hinge which define the second cavity. The two cap portions, when moved relative to each other via the living hinge, permit access to the healing screw. In an alternative embodiment, the cap includes two retention members sized and configured to grip the healing screw. To remove the healing screw from the cap, the two retention members are displaced apart from each other by engaging them with a wedge extending from the vial.

  • Patent number: 5947735
    Abstract: A self-tapping dental implant includes a body which is substantially covered by a random surface roughening without adversely affecting the cutting edge and thus the amount of torque needed to thread the implant into bone tissue. During the surface treatment process, the cutting edges of the implant are covered with a removable shield. The shield may engage the implant through openings on either side of the cutting edge. The shield is adaptable for use with implants having multiple cutting edges since the shield may include a plurality of arms connected by a base. The shield may be snapped onto the distal end of the implant.
