For obtainig resistance form and retention form in conventional rules of cavity preparation, it was necessary to extend the cavity outlines until no undermined enamel remains and all the extending fissures or connecting pits and fissures on the occlusal surfaces of the teeth, and to avoid the weakened cavity wall even if they were sound enamel and dentin. However, it should be reconsidered that the high carious resistance of the enamel must bring the teeth longevity. The recent advances in adhesive dentistry makes it possible that the stable bonding between restorative resin composities and teeth substance could be established by not only mechanical and adhesive retention but also chemical bonding. Moreover, the restorative resin composites are expected to restore the defected teeth and to recover its function, as so-called bio-materials. In this paper the conservative cavity preparation based on a new concept was proposed to minimize an elimination of the sound enamel and dentin.
