Amalgam outperforms composite in range of posterior cavity types

shutterstock_123309112

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 .

40 studies were identified for this review of dental implants in irradiated patients. While survival rates were good, they were lower than in non-irradiated areas. As the majority of the included studies were retrospective the findings should be viewed cautiously.

38 studies were included in this review comparing survival rates of turned and anodised-surface dental implants. The findings suggest that turned implants have a higher failure rate but the evidence is limited as the review includes a substantial proportion of retrospective studies.

Six studies were included in this review comparing the success rates of self-drilling and self-tapping mini-screws in orthodontic practice. The findings suggest no difference but the studies were small and of short duration and none of the included studies was a randomised trial so the findings should be interpreted cautiously.
