  • Dental matrix band seal in combination with a matrix band
    Publication number: 20050221255
    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.
