Bulkfill flowable composite resins – A review

Abstract

Flowable composite resins are widely used in clinical practice. Bulk Fill flowable resins with improved mechanical and chemical characteristics have recently been introduced. These composites are low‑viscosity materials with the reduced percentage of inorganic filler particles and higher amount of resinous components. Consequently, the polymerization process leads to volumetric contraction, but with minimal stress contraction. Flowable composites, with their low elastic modulus compete with stress development, potentially helping to maintain the marginal seal of the restoration. The flowable composites are readily workable and adaptable to cavity walls and their use can reduce marginal defects in restorations. This review enlighten various aspects of bulkfill flowable composite resin materials.
