Extensive silver amalgam restorations in premolars and molars occasionally require sacrifice of healthy unsupported enamel walls or cusps. Unsupported enamel is prohibited because it may lead to cuspal fractures in large silver amalgam restorations and complicated, posterior silver amalgam restorations also lack esthetics. Inserting composite resin veneers to disguise silver amalgam restorations has been proposed. Large hybrid composite resin restorations in posterior teeth are more conservative and esthetic than are silver amalgam restorations, but researchers agree that composite resins commonly exhibit few drawbacks and they are unsuitable for stress bearing restorations. A conservative approach to the treatment of wide and deeply carious posterior teeth; an alternative to the use of retentive form, is described in this study. The technique involves reinforcing the thin cavity walls or undermined cusps for conservative restorations with a posterior composite resin. The new cavity preparation can be restored with a silver amalgam that ensures occlusal resistance and an acceptable marginal seal.
