ABSTRACT:
An improved prophylaxis cup (10) formed of a silicone elastomer incorporated with a pumice material (17) uniformly incorporated throughout the cup and mounted on a mounting button (11) in a non-disposable dental handpiece (110 ) is described. After a teeth cleaning procedure, the prophylaxis cup is disposed of and the mounting button and the dental handpiece are sterilized for reuse. The mounting button is comprised of a bulbous mounting head (23) having a circular cross-section that mates with a similarly shaped cavity (19) in a mounting section (13) of the cup. The cavity is preferably about 5 to 15 percent smaller in cross-sectional diameter than the mounting head so that the cup must be stretched over the mounted head for mounting the cup on the mounting button. A working section (15) of the cup is provided with a conical recess (15c) that wears down as the teeth are being cleaned to provide continuous application of fresh abrasive to the tooth surface. The prophylaxis cup mounted on a disposable dental handpiece or angled attachment (210) is also shown Further, the process for manufacturing the prophylaxis cup is described.
