Imperceptible bonded composite resin Class III restoration using labial access

Proper use of modern composite resin materials precludes the need to mask Class III restorations behind residual labial enamel. With the use of micromechanical enamel bonding, chemical adhesion to dentin, and traditional mechanical interlocking, visible Class III composite resin restorations that exactly simulate the color and texture of natural enamel surfaces can be placed. Such imperceptible restorations, when performed properly, can last for many years. This paper details a step-by-step procedure for restoring a Class III carious lesion with composite resin, using labial access and a recently introduced dentinal and enamel bonding agent.
