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.

Conditions

  • Decayed Teeth
  • Malposed Teeth
  • Endodontically Treated Teeth
  • Teeth Restored With Large Filling Restorations
  • Single Anterior Crowns
  • Single Premolars Crowns

Interventions

OTHER

lithium disilicate (IPS e-max) ceramic crown

monolithic lithium disilicate ceramic crown

OTHER

New gradient technology zirconia (5Y-TZP\ 3Y-TZP) IPS e.max ZirCad Prime ceramic crown

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

OTHER

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
