ABSTRACT:
A dental device includes an angular matrix (1), with a shape reproducing the shape of the zone of a tooth (3) on which an operation is performed. The matrix (1) is made of synthetic material transparent to light radiations used for photopolymerization of composite resins. Forceps (2), also similarly transparent, have ends (2',2") which, with the forceps (2) locked, form with their inside surfaces (2"',2.sup.IV) a shape also substantially equal to that of the tooth (3). The matrices can be right or left and modeled for large incisors, small incisors or canine teeth. During the operation, the matrix (1) is kept in position simply by the lateral thrust exerted by the forceps (2) on a flap (1") extended along the contour of the matrix (1) and located substantially perpendicular to the matrix (1) itself.
