Abstract
The present invention provides a dental prophylaxis angle that includes a housing, a drive shaft, and a rotor. The housing may define a first bore and a second bore in communication with the first bore. The drive shaft is positionable in the first bore and may include a distal bearing surface. The rotor is positionable in the second bore and can be driven by the drive shaft. Further, the rotor rotates about a first axis. The second bore can further include a side surface, a plane perpendicular to the first axis that intersects both the side surface and the distal bearing surface. The drive shaft and the side surface of the second bore can operate together, against a common surface of the rotor, to prevent removal of the rotor from the second bore in a direction along the first axis.
