Brief Summary

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

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).

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=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.
