Title Survival Rate For Single Tooth CAD/CAM Restorations as Compared to Conventional Dental Restorations is Inconclusive
Clinical Question In a healthy adult in need of a single-tooth restoration, will a CAD/CAM restoration have a better survival rate compared to a conventional restoration?
Clinical Bottom Line For patients in need of a single tooth restoration, there is a lack evidence that directly compares CAD/CAM restorations to conventional dental restorations.

Comments on
The Evidence
In the Wittneben review article, none of the studies included in the review were randomized controlled trials, but each article was reviewed for validity. A detailed search was included for all trials. 1,957 restorations were compiled and a meta- analysis was done. While this study analyzed the survival rate of CAD/CAM restorations, there was no comparison to conventional dental restorations.
Applicability The subjects and treatment procedures could easily be applied to any general practice setting. The initial cost of CAD/CAM systems can be a deterrent for some dentists.
