Device for the reconstruction of an angular zone of a tooth.

摘要

The device comprises an angular matrix (1), with a shape reproducing the shape of the zone of tooth (3) on which the operation is performed, of synthetic material transparent to light radiations used for photopolymerization of composite resins, and forceps (2), also similarly transparent, with ends (2 min , 2 sec ) which, with the forceps locked, forming with their inside surfaces (2 sec min , 2) a shape also substantially equal to that of said tooth (3). The matrices can be right or left and modeled for large incisors, small incisors or canine teeth. During the operation, matrix (1) is kept in position simply by the lateral thrust exerted by forceps (2) on a flap (1 sec ) extended along the contour of matrix (1) and substantially perpendicular to matrix (1) itself. Matrix (1) exhibits a hole (1) for the escape of air, made in zone opposite the apex of treated tooth (3).
