ABSTRACT:
A dental strip comprised of uniformly thick, dead soft polymer, for use as a matrix in molding hardenable restorative materials. Matrixing processes for the strip permit the formation of interproximally contacting restorations without wedging; and the formation of composite restorations with smooth interproximal margins. Other processes for the strip permit the formation of removable restorations which are separated from prepared tooth surfaces by the strip; the formation of restorations with reduced resin excess; and stabilization of the strip on dental surfaces by affixing with a temporary adhesive.
