Patent number: 8771285Abstract: A drive tool for accepting and rotationally locking the head portion of an orthopedic screw, such as a dental implant, to impart driving torque to the screw. In one exemplary embodiment, the drive tool includes an elongate body having an opening at its proximal end which is sized to receive the head portions of at least two different dental implants, the head portions of the dental implants being oriented at different angles with respect to the implant body portions. When the head portion of an implant is received within the opening, the drive tool is rotationally locked with respect to the implant. In this position, the body of the drive tool remains oriented so that same is substantially colinear with the body portion of the implant. Although the invention is described in the context of a drive tool used with a dental implant having a body portion and a head portion or abutment portion, the invention is more broadly applicable to drive tools which may be used with other types of orthopedic screws.Type: GrantFiled: September 15, 2006Date of Patent: July 8, 2014Assignee: Zimmer Dental, Inc.Inventors: Ryan M.

Publication number: 20090065376Abstract: 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.Type: ApplicationFiled: November 17, 2008Publication date: March 12, 2009Inventors: Ryan M. Donahoe, Nathan J. Meyer, Thomas H. Day, Christopher M. Gervais, Fred Murillo
