ABSTRACT:
A medical tool such as a prophy angle is provided having primarily plastic parts to make disposing more economical. A portion of the drive shaft is made of metal to eliminate detrimental deformation. The housing is made of two plastic halves which snap-fit together and have projecting portions which surround a pair of oversized plastic beveled gears. A prophy cup having a locking projection is provided so that the locking projection fits into locking cavity on a stud of the tool. Vanes are disposed on the inside of the cup and have a step-like configuration to aid in retaining polishing paste in the cup.
