Polymerization Shrinkage In Composite Resin

Visible light polymerizing composite resins have been the material of choice for esthetic restorations.In the last few decades, adhesive dentistry has evolved remarkably, greatly due to the development and incorporation of new monomers, new initiation systems and filler technologies which improve the physical properties of these materials. Composite resins, however, have one deficiency : they all contract, causing dimensional changes, during photopolymerization. Such contraction is termed polymerization shrinkage.The purpose of this book provides you with an in depth understanding of the origin of polymerization shrinkage, polymerization reaction, various factors involved in the process of polymerization shrinkage, the clinical factors affecting polymerization stress and methods to minimize the shrinkage ,the various material science advances and techniques that are currently available to deal with polymerization shrinkage in a clinical practice.
