This review of inlay-retained fixed dental prosthesis included 11 small mainly observational studies. The studies suggest a 3-yr survival rate of 92.6% (95% CI: 85.8-97.6%) and 5-yr survival rate of 87.9% (95% CI: 77.4-96.1%). However because of the low quality of the available studies and the wide range of inlay designs, framework materials, surface treatments and cement systems used means that the results should be interpreted cautiously.

Mark-Steven Howe looks at a review of complete overdentures supported on mini-implants. Although 24 studies are included the majority are small and short term so while good overall overdenture survival was seen the results should be interpreted with caution.

This review of survival and complication rates of resin-bonded fixed dental prosthesis included 209 studies. The findings suggest overall survival rates of 91.3 % (95%CI; 88–93.7) . The quality of the available studies suggest that this should be interpreted cautiously.

5 studies at high risk of bias were included in this review of the success of restoration in posterior root filled teeth findings suggest that the more tooth remaining teh better the treatment outcome.

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 .

Only 4 studies were included in the Cochrane review of the impact of rubber dam isolation on dental restorations. The findings suggest that using rubber dam may results in lower failure rates

This review of the failure rates of all-ceramic crowns included 14 (9 prospective, 5 retrospective) studies. Using a broad definition of failure there was little difference between rates in anterior and posterior crowns.

Only 3 RCTs could be identified for this review of the long-term performance of direct versus indirect composite inlays/ onlays in posterior teeth. the limited quality of the studies provide insufficient evidence to recommend direct over indirect techniques.

Only 19 small studies were identified for this review of the survival rate of removable dental prostheses. the Heterogeneity of the studies and evaluation criteria made comparisons difficult so findings should be interpreted with caution.
