Clinical Assessment of Indirect Restoration Fabricated From Nano Hybrid Composite Blocks Versus Ceramic Blocks in Badly Broken Teeth One Year Follow up

Clinical Assessment Accourding to Modified Usphs"of Indirect Restoration Fabricated From Nano Hybrid Composite Blocks Versus Ceramic Blocks in Badly Broken Teeth One Year Follow up Randomized Clinical Trial

The aim of the study is to compare one-year clinical performance of indirect restoration fabricated from nano hybrid composite CAD CAM blocks and ceramic blocks

This research is conducted for comparing the clinical efficacy of nano hybrid composite blocks and ceramic blocks ., the choice of nano hybrid composite blocks based on the claim of the manufacturer, as it's considered to be promising , nano hybrid composite blocks has the highest fillers content (86% by weight), resembles natural teeth perfectly , Excellent physical values for flexural strength and abrasion, No firing required (a real one step ), can be processed using any conventional milling unit, can be finished and polished optimally, Ideal for grinding even in cases with thin edges.
