Advances in technology and adhesive dentistry have allowed practitioners to achieve long-term restorative results with minimal damage to tooth structures. The use of bonded restorations in restorative dentistry, including placement of resin composite restorations, has largely replaced the use of amalgam. The clinical case presented describes a technique utilizing minimal cavity preparation aimed at improving the quality and longevity of a Class I resin composite restoration. The procedure includes the use of an occlusal index to restore the tooth back to its original contour and anatomy. Other factors discussed are the use of MMP inhibitors, new advances in bonding agents, proper light-curing technique, and minimal finishing and polishing of the restoration.
