Abstract :

In 1956, resin composites have been introduced as restorative material in dentistry.
Manufacturers have been working on the development of new resin composite by modifying filler
particles and resin matrix. Although recent resin composites have been developed for clinical used,
the polymerization shrinkage is remained. The shrinkage is an intrinsic property of the methacrylate
resin matrix, which results in dimensional change during polymerization. Recently, non-methacrylate
resin matrix has been developed to overcome the polymerization shrinkage problem.
