Title No Reliable Evidence To Show Improved Longevity Of Direct Composites vs. Porcelain Veneers
Clinical Question In a healthy patient who desires esthetic restoration of anterior teeth, does direct resin composite restoration offer better longevity, strength, esthetics, and conservation of tooth structure than a porcelain veneer?
Clinical Bottom Line There is no reliable evidence to show a benefit of one type of veneer restoration (direct or indirect) over the other with regard to the longevity of the restoration. (See Comments on the CAT below)

The Tyas (2004) reference in this CAT is not a “Systematic Review” but rather is a “commentary” on the Wakiaga et. al. Cochrane Review which was originally published in 2004.
by Paula W Herber, DDS () on 05/24/2011
While direct resin composite restorations offer a more conservative option than porcelain veneers, all other aspects of a porcelain veneer are far superior to a direct resin composite restoration.
