Polymerization contraction force of packable composites.
J. R. A. Pearson, M R Bouschlicher · PubMed · 2002
The maximum rate of shrinkage force development and maximum contraction force was evaluated for four packable composites and a hybrid composite control. One of the packable composites demonstrated a significantly higher maximum force rate and maximum force than the other materials; the three remaining packable composites had maximum force rates and maximum forces that were statistically similar to the conventional hybrid composite control.
