About

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

Full description

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.

26 participants in 2 patient groups

zirconia reinforced lithium silicate glass ceramic

Experimental group

Description:

It represent a new generation of glass ceramic material, enriched with zirconia (10% by weight), the material offers natural esthetics with successful outcome.

Treatment:

Other: zirconia reinforced lithium silicate glass ceramic

monolithic zirconia

Active Comparator group

Description:

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.

Treatment:

Other: zirconia reinforced lithium silicate glass ceramic
