The unavoidable, inherent property of polymerization shrinkage in composite resins generates stresses in direct composite restorations which are detrimental to composite material, prepared tooth structure and interfacial bond. Several restorative techniques have been advocated to minimize these stresses and increase the restoration success rate. One such technique is the split-increment technique which is based on the concept of diagonal pre-cure splitting of horizontal increments for the relief of shrinkage stresses by creating contraction joints in each composite increment prior to light curing. This mini review aims to revisit this concept for enhancing its understanding and providing more concise guidelines for its application in moderate-to-large cavities in the cervical, occlusal, and proximal areas.
