Prepolymerized filler in dental restorative composite |
摘要 |
<p>A dental composite having high filler loading and low shrinkage thereby providing good strength and marginal integrity. Through the use of prepolymerized filler particles in combination with a structural filler and a nanofiller, the composite exhibits very low shrinkage and is useful in stress bearing restorations and in cosmetic restorations. The structural filler used is ground to a mean particle size of less than 0.5 mu m and the nanofiller has discrete particles of a mean particle size less than 100 nm to improve handling and mechanical characteristics. The prepolymerized filler particles also allow for less viscosity and better handling characteristics of the composite. <IMAGE></p> |
