This review of failure rate of single-unit prostheses versus direct restorations in vital posterior teeth included 14 studies (5 RCTs) finding that composite had a significantly higher failure rate than amalgams, regardless of the remaining tooth structure. For teeth with fewer than 2 remaining walls, direct restorations presented significantly higher failure rates than crowns .
