Abstract
A prophy angle dental tool comprises a disposable attachment to an air turbine type of dental tool drive motor. The disposable attachment has a single section tubular body that extends from a direct drive coupling with the drive motor power shaft housing to the driven dental implement. A quick-coupling hub at one end of a medial drive shaft receives a lug drive mechanism in the motor drive shaft. Externally, the coupling hub is confined to coaxial rotation within the motor shaft housing. The medial drive shaft extends unrestrained from the motor coupling hub along an internal void within the tubular body into geared engagement with a short shaft. The short shaft is rotatively driven about an axis that is substantially transverse of the tubular body length. A pinion gear on the inner end of the short shaft is engaged by a gear at the end of the medial drive shaft thereby driving the short shaft while simultaneously holding the short shaft within a short shaft housing bore.
