Anatomically contoured matrix bands for use in dental restoration procedures

摘要

The invention comprises an asymmetrically shaped matrix band. The asymmetrical shape of the matrix band provides form for molding a dental filling into a shape that closely approximates the asymmetrical and generally trapezoidal shape of a tooth. The matrix band comprises a cross-sectional area that curves asymmetrically in the vertical direction along a curve that is constrained by two radii. The first radius is applied near the top of the matrix band and has a magnitude that is approximately one third of the magnitude of the second radius that is applied at the bottom of the matrix band. The curvature of the cross-sectional area enables the matrix band to also provide form for molding a dental filling with a contact point in the anatomically correct location on a restored tooth.
