Patent ID: 8771285

Claim:
A drive tool for rotatably driving one of at least two dental implants, the dental implants having head portions divergent from one another, said drive tool comprising: a body defining a longitudinal axis, a proximal end, a distal end, and a surface extending between the proximal end and the distal end; a drive fitting at the distal end, the drive fitting comprising one of an internal and an external polygonal fitting; a cavity for receiving one of the at least two dental implants, the cavity defined within the proximal end, the cavity comprising a wall defining a first cavity portion having a cross section extending collinearly with the longitudinal axis, the cavity further comprising a second cavity portion having a cross section extending at an acute angle relative to the longitudinal axis, the second cavity portion comprising an opening on the surface; at least on flat driving surface in the first cavity portion for non-rotatably engaging one of the at least two dental implants; a coronal wall at a coronal end of the first cavity portion extending perpendicularly to the longitudinal axis; and an acute wall in the second cavity portion extending at an acute angle to the opening.
