The effects of surface roughness and surface area on the retention of crowns luted with zinc phosphate cement.

چکیده
The retention of cast gold crowns luted with zinc phosphate cement to smooth and rough surfaced extracted teeth was examined. No significant difference in retention was observed between smooth and rough surfaced teeth. A significant linear association existed between the surface area of the teeth tested and the retentive force but, statistically, area could not be used as a useful predictor for crown retention.

The Effect of Abutment Surface Roughness on the Retention of Implant-Supported Crowns Cemented with Provisional Luting Cement
Introduction: Surface roughness can increase the retention of castings by ridges and grooves that are microretentive. This study compared the retention of implant-supported crowns when used with 3 different surface roughness abutments and one temporary cement. Methods: Thirty solid abutments (ITI), 4 mm high, were divided into three groups randomly. In the first group, 10 abutments were roughen...

متن کاملComparative Study of Microleakage of Full Crown Resterations Luted with Ariadent and Harward Zinc Phosphate Cements
Film thickness, strength, solubility and microleakage of dental cements are essential factors in cement selection by dentist. Since failure of metal ceramic restorations is mostly due to their marginal leakage and provious studies have shown that microleakage of Resin, Glassionomer and Zincphosphate cements are different, this study was done to compare the rate of microleakage between Ariadent ...
