Endodontically Treated Teeth Clinical Trial
Official title:
One Year Clinical Evaluation of Shade Matching and Patient Satisfaction of New Gradient Technology Monolithic Zirconia (5Y-TZP\3Y-TZP) Compared to Lithium Disilicate Crowns in Dental Esthetic Zone (Randomized Clinical Trial)
Although zirconia is widely used for fabrication of restorations, the 3Y-TZP zirconia where limited for posterior region for its high strength and bad esthetic. While the 5Y-TZP zirconia is limited for the anterior region due to its good esthetic and low strength. For that reason, the introduction of the new gradient technology zirconia (5Y-TZP\3Y-TZP) (IPS e.max Zircad Prime) has offered a solution to solve this problem be combining the esthetic of 5Y-TZP and the high strength of 3Y-TZP. The aim of the present study is to evaluate shade matching to natural tooth and patient satisfaction of the new gradient technology zirconia (5Y-TZP\3Y-TZP) and lithium disilicate ceramic crowns.
