Abstract
A disposable, securely retained dental angle is provided. The angle includes a one-piece hollow housing having a short leg at its front end, which is angled with respect to the long leg. Both the short and long legs have a through bore. The short leg has an aperture, which is connected to the bore of the long leg to allow insertion of a driving shaft through the short leg of the angle. A driven rotor is inserted in the short leg. A horse-shoe-like snap rotor retainer fits within the short leg over the driven rotor to retain the driven rotor in the angle. A paw-like or, alternately, a horse-shoe-like locking means fits within the long leg over the driving shaft to lock the driving shaft in the angle and to retain the angle together. In one embodiment, a pair of splinters on the driven rotor provides the function to retain the rubber prophy cup firmly while the driven rotor is in operation.

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.
