Anatomically shaped blue and transparent posterior matrices. The transparent range has colour coded matrix ends for easier use. The new and unique colour blue, as alternative to the transparent, was chosen for a better contrast to the tooth structure and the negligible influence to the composite conversion rate. This is a big advantage for a better visual control of the composite application, filling procedures and handling. There is no discoloration of the dyed matrix when in contact with etching gels, bonds and primers. The blue line is a step forward in simplifying and accelerating the dentists’ everyday job. Matrix 0.075mm thin.
