The dental prophy angle adapter can include a drive shaft with a tip. The drive shaft of the adapter can be coupled to a gear at the same end of the tip with the rotor of the prophy angle being configured to receive the tip. Further, a slidable sleeve can extend over a portion of the drift shaft so that the slidable sleeve becomes automatically retracted upon engaging a shoulder of the housing resulting in the gear of the drive shaft being positioned beyond the end of the slidable sleeve.

Abstract: A dental system comprises a dental prophy angle and an adapter. The prophy angle includes a housing and a latch mechanism. The adapter is configured to drive the prophy angle. The latch mechanism includes a lever and a first latch element, which are both defined by a pair of opposing U-shaped slots within the housing, such that free ends of one of the pair of opposing U-shaped slots are disposed between free ends of the other of the pair of opposing U-shaped slots. The adapter includes a nose having a second latch element and a depression proximate to the second latch element. Upon the first latch element mating with the second latch element, the depression is positioned adjacent the lever.

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.
