摘要: The hardening stresses in wall-to-wall bonded composites were measured and related to calculated values obtained from freely shrinking materials. Since the ultimate tensile strength of materials contracting under restricted conditions was not lower than that which hindered during polymerization shrinkage, conclusion drawn contraction compensated for by flow instead internal disruptions.
