Abstract
A dental dam clamp comprises first and second spaced, opposing jaws and respective first and second tooth engaging portions on the jaws. The first and second tooth engaging portions are positioned in confronting relation to one another and are biased toward one another by a resilient member when the jaws are moved outwardly from a free state defining a first position of the jaws. In one embodiment, first ends of the tooth engaging portions are spaced closer together than the second ends of the tooth engaging portions when the jaws are in the first position. The spacing between the first ends of the tooth engaging portions may be substantially the same as the spacing between the second ends of the tooth engaging portions when the jaws are moved outwardly to a second position. In another embodiment, the tooth engaging portions include friction-increasing surfaces to help secure the clamp to a tooth.

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.
