Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
183 words
A universal occlusal matrix for application to the occlusal surface only of a tooth having a central groove forming a V-shape in cross section, the universal occlusal matrix consisting essentially of: an elastic lamina made from a material that is transparent to ultraviolet rays and to rays of the visible spectrum to permit rapid hardening by polymerization of the filling material and which material does not adhere to that of the said filling; the 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; and the elastic lamina extending away from the central groove sufficiently far to cover and mimic the occlusal surface only of a human tooth, wherein the human tooth is selected from the group consisting of the right and left maxillary first premolar, right and left maxillary second premolar, right and left mandibular first premolar, right and left mandibular second premolar, right and left maxillary first molar, right and left maxillary second molar, right and left mandibular first molar, and right and left mandibular second molar.

Claim 13
Independent Claim
159 words
A method of filling a tooth, wherein the tooth has an occlusal surface only having a central groove forming a V-shape in cross-section, the method consisting essentially of the steps of: applying filling material to a cavity in the occlusal surface only of the tooth; selecting an elastic lamina made from a material that is transparent to ultraviolet rays and to rays of the visible spectrum to permit rapid hardening by polymerization of the filling material and which material does not adhere to that of the said filling, the 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 extending away from the central groove sufficiently far to cover and mimic the occlusal surface only of the tooth; applying the elastic lamina to the occlusal surface only of the tooth; hardening the filling; and removing the elastic lamina from the tooth.
