Absolute is a high-strength core composite that cuts like dentin. It is a highly-filled automix dual cure resin that is expressed directly from the cartridge to the tooth. There's no need for hand mixing or triturating. Absolute Dentin stacks great and preps beautifully. It gives you a stronger core that resists flexing. It is densely filled (75%) with fluoride/barium glass. It provides strong, stable support for your restorations.
