A report of anterior In-Ceram restorations.

Thirty-one patients were restored with 35 anterior crowns and 7 anterior fixed partial dentures. The restorations were fabricated in In-Ceram, an all-porcelain ceramic material. The restorations were evaluated for fractures, tooth wear, recurrent caries, gingival inflammation and tooth sensitivity in a 21-month follow-up. Three of the 35 crowns fractured. The failure for the crowns was 8.5%. The remaining crowns provided excellent function and aesthetics. They had been in the mouth between 2.5 and 21 months. There were no fractures in the 7 fixed partial dentures. These had been in service between 4.5 and 21 months. More long-term clinical studies are recommended to determine the survival of In-Ceram fixed partial dentures.
