The most common material used to fill Class II restorations in posterior teeth is resin-based composite (RBC). Despite the popularity of RBC restorations, there are challenges to placing them properly. Improperly shaped restorations with sharp edges and corners will chip and fracture, resulting in premature failure. Properly placed RBC restorations will duplicate the embrasures, contact area, marginal ridge, and occlusal fossa of natural teeth. RBC restorations should mimic the smooth and rounded contours of the natural dentition to ensure longevity.
