ABSTRACT


Aim: To Compare One-year Clinical Performance Of Indirect Restoration Fabricated From Nano Hybrid Composite CAD CAM Blocks And Ceramic Blocks In Restoration Of Badly Broken Vital TeethMethods And Materials: In Two Parallel Groups (n= 42 Restorations), 39 Participants Having Badly Broken Vital Teeth Minimum Of Two Remaining Wall Were Randomly Enrolled In This Trial And Received Either Resin Composite Blocks (Grandio, VOCO, Germany) Or Ceramic Blocks (E.max). Fabricated Restorations Were Cemented According To The Manufacturers? Instructions With The Corresponding Adhesive System. The Restorations Were Assessed Using ModifiedUSPHS Criteria By Two Independent Blinded Assessors At Baseline And 1-year Follow Up Visits. Data Was Obtained And Analyzed Using Independent Student-t Test, Chi-square And McNemar Test For Inter And Intragroup Comparisons. The Significance Level Was Set At ? 0.05.

Results: All The 39 Participants Completed The Trial. There Was No Statistically Significantdifference Between Both Tested Materials For All USPHS Criteria Except For Cavo-surface Marginal Discoloration Favoring Grandio Blocks.

Conclusions: Both Materials Showed An Acceptable Successful Clinical Performance Along 1-year Follow-up Period.
