Micro Motors Inc. introduces the Micro PHP, a hygiene handpiece designed specifically to be used with disposable prophy angles.
  - The handpiece accommodates variable dimensions of disposable prophy angles, unlike traditional low-speed handpieces.
  - A chuck mechanism eliminates distortion and breakage of the angle shafts, allowing for a simple push-on, pull-off angle connection.
  - All brands of disposable angles seat securely on the straight attachment to facilitate a more efficient polishing motion.
