Disposable prophy angle

A brushhead for a toothbrush having a particular bristle configuration which includes a plurality of bristle tufts arranged in three columns and nine rows, wherein the distal end two adjacent rows and the proximal end two adjacent rows and an intermediate row have longer bristles than the remaining bristle tuft rows. The distal, intermediate and proximal bristle tuft rows all have pointed tips (in the lateral direction) and beveled outside edges at the top portion thereof. The shorter bristle tuft rows also have beveled outside edges. The shorter bristle tuft rows between the distal and intermediate rows have angled top surfaces in addition to the beveled outside edges.

Brushhead for a toothbrush

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.
