Clinical Trial Summary

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.


Description:

Restorative dentistry is a mix of science and art. The success of restorative dentistry is determined on the basis of functional and esthetic results. Closely matching natural teeth with an artificial restoration can be one of the most challenging procedures in restorative dentistry. Natural teeth vary greatly in color and shape.The color of a ceramic restoration is affected by the shade of the ceramic material, its thickness, and, the color of the underlying material. The restoration's color is influenced by ceramic firing temperature, the color of the prepared tooth, translucency and thickness of veneering porcelain. The rational of this study is newly introduced gradient technology zirconia (5Y-TZP\3Y-TZP) (IPS e.max Zircad Prime) with improved optical properties to solve the drawbacks of esthetic properties of zirconia. Null hypothesis of the study will be: - There would be no difference in shade matching of the new gradient technology zirconia (5Y-TZP\3Y-TZP) and lithium disilicate ceramic crowns used in the esthetic zone. - There would be no difference in patient satisfaction of new gradient technology zirconia (5Y-TZP\3Y-TZP) and lithium disilicate ceramic crowns at baseline, 3, 6, 9, 12 months used in the esthetic zone.

conjunction with the two zirconium oxide raw materials 3Y-TZP and 5Y-TZP is responsible for producing a continuous, seamless progression of the shade and translucency within the material
natural tooth
natural tooth is composed of enamel. Enamel is on the surface of every tooth and it has a natural hue of white. However, the underlying dentin layer has a slightly yellowish color. This yellowish hue shows through the enamel in almost everyone
