Abstract
A universal occlusal matrix for application to the occlusal surface of a tooth having a central groove forming a V-shape in cross-section, the universal occlusal matrix being transparent to ultraviolet rays and to rays of the visible spectrum to permit rapid hardening by polymerization of the filling material and of a material which does not adhere to that of the said filing. The universal occlusal matrix has an elastic lamina having a central groove forming a V-shape in cross-section with first and second curved concave wings extending outward from the central groove. The elastic lamina extends away from the central groove sufficiently far to cover the occlusal surface of the various teeth to which it may be applied. The angle of the V-shape of the groove of the lamina is greater than the angle of the V-shape of the groove of the various teeth to which it may be applied. The elastic lamina is characterized by having wings whose radius of curvature is less than the radius of curvature of the cusps of the various teeth to which it may be applied.
