Ideal system for micro-restorations and for the treatment of unilateral composite fillings in posterior teeth. Sectionals are carefully preshaped just like the original tooth. Thin matrices, available in steel or transparent plastic. Transparent approximal shaper allows perfect adaptation and shaping of sectionals in interdental spaces. The combined effect of wedges and approximal shapers allow continuous adaptation of sectionals along the total approximo-cervical filling margin. Thickness: 0.05mm.
