摘要:
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.
