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) |

by John Rugh (San Antonio, Texas) on 08/14/2011 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. | |
