Bondfill SB is a self-cure, self-adhesive resin for dental restorations. It contains 4-META/ MMA-TBB. Though it requires no bonding agent, Bondfill SB forms strong bonds to enamel, dentin, and restorative materials without gapping and discoloration. It is also designed to absorb intense, complicated complex eternal stresses and greatly resist wear. The Powder contains PMMA and TMPT reactive organic filler which creates a tough restoration that is hard yet still very resilient.
