Abstract

A coated matrix band or coated separating strip for use in dentistry eliminates capillary action between a tooth and the matrix band due to the coating while the tooth is being filled, while at least one aperture in the matrix band assists with removal of the matrix band from the tooth, after the filling is complete. The improvement in the coated matrix band or coated separating strip is a coating applied to the surface thereof in order to minimize the ingress of fluid between the tooth and the device as the tooth is being filled. At least one aperture therein assists with the removal from the tooth after the filling is complete.

CROSS REFERENCE TO RELATED APPLICATION

[0001] This application incorporates by reference U.S. patent application Ser. No. 10 / 238,295 as originally filed on Oct. 23, 2002, by the same inventors.

[0002] This invention relates to a matrix band and more particularly to a dental matrix band seal in combination with a matrix band or a separation strip for use by a dentist to provide a framework for applying cavity filling material to a tooth; which minimizes, if not eliminates, capillary action which causes at least one body fluid to flow into the area between the matrix band and the tooth being filled and does not adhere to the cavity filling material. BACKGROUND OF THE INVENTION

[0003] A matrix band is a common tool used in dentistry. Typically, the matrix band is a thin, flexible piece of material. Generally speaking, the matrix band is metallic in nature. A dentist will position the band around a tooth to be filled. The band is then tightened around the tooth, with a clamping device, i...
