Several failures have been related to amalgam restorations that requiring repair or replacement. The aim of this cases report was to demonstrate a usual clinical condition found in dental office: fractured amalgam associated with the esthetic patient desire. Then, seven fractured amalgam restorations replacements, probably due to improper cavity design, were performed in two patients. The replacements were accomplished by three different operators. It was applied a multi-mode adhesive system using the selective enamel etching technique and a nanofilled resin composite with good mechanical properties and polishing. At the end, satisfactory esthetic results were achieved for all restorations. However, differences among operators were detected, highlighting the importance of professional training and esthetic patient desire. Thus, it was concluded that the resistance and retention form of amalgam cavity was the major concern on the failed amalgam restorations in this study. Amalgam restorations must be repaired or replaced carefully to avoid damage to the remaining dental substrate and resin composite has been the preferred option for replacement, since it is more conservative and esthetic
