Abstract
The patient’s demand for tooth-colored restorations increased the use of resin composite materials for posterior restorations. Polymerization shrinkage
is a common problem associated with light-cure composite resins. Among the
recent advances that have been adopted to control the polymerization stresses
is the development of bulk fill composites. These materials generally have higher filler loads, which make them highly viscous, sticky, and difficult to manipulate, resulting in problems during placement. Thus, they are difficult for handling with deficient marginal adaptation to the preparation wall. Reducing composite viscosity was attempted by different techniques to improve the adaptability to the cavity walls and margins thus improving the clinical performance.
