Clinical research on bonded amalgam restorations. Part 2: Further studies and clinical technique

In vitro studies show that the adhesive amalgam technique is superior to the nonadhesive technique. Also, early clinical results indicate that the adhesive technique can eliminate the microspace between amalgam and tooth. And, it can retain amalgam on unprepared occlusal surfaces of molars and premolars, sealing the fissures. Moreover, amalgam can be retained in preparations without undercuts. Early results indicate in traditional preparations, the adhesive technique appears to be at least equivalent to nonadhesive technique.
