Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

zirconia reinforced lithium silicate glass ceramic

Intervention Type OTHER

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.

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.

Group Type ACTIVE_COMPARATOR

zirconia reinforced lithium silicate glass ceramic

Intervention Type OTHER

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.
