Evaluation of Patient Satisfaction and Color Difference Between Natural Teeth and Monolithic All-ceramic Crowns Fabricated From Celtra Press Treated With Different Surface Finishing Protocols

Evaluation of Patient Satisfaction and Color Difference Between Natural Teeth and Monolithic All-ceramic Crowns Fabricated From Zirconia Reinforced Lithium Silicate Ceramics "Celtra Press" Treated With Different Surface Finishing Protocols.

investigating the effect of glazing and polishing on the color difference between natural teeth and all ceramic crowns made from celtra press (zirconia reinforced lithium silicate ceramic).

Study Overview

• Status: Unknown
• Conditions: Natural Optical Properties
• Intervention / Treatment: Other: polished celtra press full coverage crown; Other: glazed celtra press full coverage crowns; Other: contralateral natural teeth

Detailed Description

Two groups of patients will be selected according to special inclusion criteria N=5 in each group total of 10 patients, one of the two groups will receive a glazed zirconia reinforced lithium silicate ''celtra press'' crowns and the other group will receive a polished ones of the same material , after crowns delivery color difference (ΔE) between the natural teeth and the celtra press crown will be measured by a spectrophotometer device (intra oral) and patient satisfaction will be recorded.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
color match	Color match will be measured using "United states pulplic health service " system . Scale system : Alpha : Excellent colour match and shade between restoration and adjacent tooth, restoration almost invisible; Bravo : Slightly mismatching between the restoration and the adjacent tooth, which is in the normal range of tooth colour, translucence, and/or shade; Charlie : Obvious mismatch, beyond the normal range; Delta : Gross mismatch/aesthetically displeasing colour, shade, and/or translucence	immediately after crown delivery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Color difference	The color difference (ΔE) will be measured using spectrophotometer	immediately after crown delivery

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
patient satisfaction	Patient satisfaction using Visual Analogue scale- Binary (Satisfied or not satisfied)	immediately after crown delivery
