Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Both groups will receive Onlay preparation . Digital impression by intra oral scanner will be taken, wax pattern for the onlay restoration will be designed and milled using CAD/CAM software. After that, the wax pattern will be invested and final onlay restoration will be constructed from VITA AMBRIA and IPS e.max press ingots according to manufacturing instructions. Primary outcome: The amount of wear will be evaluated according to FDI standard.
