Abstract:
A systematic review was used to make an inventory of clinical studies on veneer restorations. Based on a protocol articles were selected that were subsequently assessed for their quality. With 'failure of the restoration' as a study outcome, survival data of the restorations were generated from the selected studies and a mean survival result was composed. Porcelain veneer restorations showed an acceptable 3-year survival, which was favourable to the 3-year survival of preformed acrylic veneers. The quality assessment expressed that reports on clinical studies should be more standardised in order to make it easier to compare the results of different studies.
