Clinical Experience With Empress Crowns


PMID: 9484056

The IPS Empress pressed glass-ceramic system was used in this investigation to restore anterior and posterior single teeth. One hundred forty-four crowns were evaluated over a period of 6 to 68 months (mean period of 37 months). According to the Kaplan-Meier analysis, the estimated success rate after this period was 95.35%. Crowns were also investigated using the modified US Public Health Service criteria. Most of the crowns rated as Alpha for color match, contour, marginal integrity, recurrent caries, and marginal discoloration. The results of this study indicate that this material can be successfully used, especially in the anterior area, when the procedures outlined are carefully followed.
