AADR Annual Meeting - Dallas, Texas - April 2-5, 2008 (Oral presentation- Program #081)
New dimer acid based resin nano-hybrid composite
A new "Low Shrinkage Nano-Hybrid Composite" (LSNHC) was developed using a free radically polymerizable dimer acid dimethacrylate which copolymerizes with existing monomers and a filler system which contains a new Ytterbium Fluoride mono dispersed nano sized particles, combined with regular Silica and Barium glass, to obtain dental composites. This composite compensates for shrinkage by phase separation.
