CAD-CAM plays a significant role in modern dentistry, it is an acronym for computer aided design and computer aided manufacturing. CAD CAM helps to fabricate precise shapes and fit for restorations especially in complex tooth restorations like inlays, onlays, crowns and bridges. All-ceramic crowns like Zirconium crowns and Emax (Lithium disilicate) crowns and implant prostheses are also manufactured with CAD-CAM.
