Study Overview
Brief Summary
evaluation of color difference between zirconia reinforced lithium silicate (celtra press) VS lithium disilicate (Emax) in relation to natural tooth structure to determine which monolithic material will provide restoration with exact shade and optical properties as natural tooth structure.
Detailed Description
eligible patients will be randomized in 2 equal group between study group (celtra press) and control group (Emax) .
Single tooth in esthetic zone requiring full coverage crown is prepared to receive an all ceramic crown of .
Grouping: The crowns will be divided into two groups:
I:Teeth receiving crowns fabricated from IPS emax press ( ivoclarvivadent) II:Teeth receiving crowns fabricatedfrom Celtrapress(dentsplysirona).
Shade will be measured using intraoral spectrophotometer and evaluated.
