Abstract
Preparation design for posterior composite restorations should differ from that for amalgam restorations in the following manner.1.Occlusal form should be narrower and the depth shallower.2.The proximal extensions (facial and lingual) should be placed in areas that can be seen, probed, and polished.3.Internal line angles should be rounded and retenive grooves placed in proximal line angles (axiofacial and axiolingual) and the gingival wall.4.Beveling is recommended for proximal margins but not for occlusal margins.
