About this trial

To compare biological, technical, radiographic, and patient-reported outcomes of two types of monolithic zirconia crowns screw-retained to implant.

To assess whether the new form of multilayered zirconia crowns will show similar survival and success rate to conventional monolithic Zirconia screw-retained to implants in molar and premolar regions.

First Null Hypothesis: Multilayered monolithic zirconia crowns would have similar survival, success rate compared to conventional monolithic zirconia implant supported crowns.

Second Null hypothesis: There would be no difference in clinical and patients related outcomes between multilayered and conventional monolithic zirconia implant supported crowns.
