Abstract
A prophylaxis cup is provided which has a lower portion and an upper portion. The lower portion of the cup is adapted to mount the cup to a driven member of a prophylaxis angle. The upper portion of the cup includes a wall having an inner surface and an outer surface. The inner surface is smooth and uninterrupted and defines a cavity having a floor and which receives prophylaxis paste. A central post extends up from the cavity floor. A continuous, uninterrupted, circumferential flange extends inwardly from a top of the wall's inner surface. A sloped working surface extends between the flange inner edge and the wall outer surface. The cup is pre-formed to define a flare or annular wedge at the outer edge of the working surface which is sized to permit the working surface to clean a tooth subgingivally and interproximally. A generally circular groove on the working surface helps hold the prophy paste. The groove spirals outwardly.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
