New Low shrinkage Dimer Acid

IADR/AADR/CADRE 85th General Session – New Orleans - March 21-24, 2007 (Oral presentation – Program #1290)

A new "Low Shrinkage Microhybrid Composite (LSMHC)" was developed using a free radically polymerizable dimer acid based resin, designed at the University of Colorado, USA, which compensates for shrinkage by phase separation. The new dimer acid derived dimethacrylate readily copolymerizes with existing monomers to obtain dental composites using standard initiating systems.
