Evaluation of Antagonist Wear Behavior and Patient Satisfaction of Monolithic Zirconia Versus Lithium Silicate Zirconia Crowns

简要概况

evaluation of wear behavior and patient satisfaction of monolithic zirconia and zirconia reinforced glass crowns after follow-up periods 0,3,6,12 months.

详细说明

two groups of patients will be selected according to special inclusion criteria n=13 in each group total of 26. each group will receive one of the crowns used in this study either ( monolithic zirconia or zirconia reinforced lithium silicate glass) after crown delivery wear and patient satisfaction will be recorded at 0,3,6,12 moths follow-up periods.

Other: zirconia reinforced lithium silicate glass ceramic
It represent a new generation of glass ceramic material. Using an innovative manufacturing process the glass ceramic is enriched with zirconia (10% by weight) for dental CAD/CAM applications for the fabrication of inlays, onlays, crowns and anterior and posterior single tooth restorations on implant abutments.

研究工具

Experimental: zirconia reinforced lithium silicate glass ceramic
It represent a new generation of glass ceramic material, enriched with zirconia (10% by weight), the material offers natural esthetics with successful outcome.
Active Comparator: monolithic zirconia
Zirconia or zirconium dioxide (ZrO2) is a highly attractive ceramic material in prosthodontics due to its excellent mechanical properties. It is widely used to build prosthetic devices.
