Danville's Contact Matrix Sectional Matrix System sets the standard for isolation and separation in Class II contact restorations. Kidney-shaped domed stainless steel matrices perfectly match tooth anatomy. The durable, stainless steel contact separation/retainer springs offer superior features:

• Inward and outward orientations allow rings to be placed in normal or reversed orientations while maintaining optimal contact of "flats" to the tooth.
• Flat-sided tines adapt better to wide preps than round cross-sectioned rings.
• Occlusal offset allows adjacent springs to stack and provides dam clamp clearance.
• Converging tines improve retention.

• (1) inward retainer spring (silver).
• (1) outward retainer spring (gold).
• (50) large lite-flex matrices.
• (50) small lite-flex matrices.
