ABSTRACT:
The present invention provides a dental prophylaxis angle that includes a singular housing, a drive shaft, a rotor, and a collar. The housing may define a first bore, a second bore in communication with the first bore at a substantial angle thereto, and a third bore coaxial with the second bore. The drive shaft is positionable in the first bore, and the drive shaft may include a post, which may define a spherical depression. The rotor is positionable in the second bore, and may define a spherical bearing and a spherical tip. The collar defines an axial bore where the collar is positionable in the first bore such that a portion of the drive shaft is disposed within the axial bore.
