<title>ABSTRACT</title>
Zirconia has recently been clinically applied as an ideal tooth color material which acquires superior mechanical properties with high stability without water absorption and dissolution with the progression of the CAD/CAM technique. Dental prosthetic materials have recently evolved to those for metal-free restoration because of the strength, esthetics and environmental protection concerning rare metals. In addition, the increase in demands for metal-free restoration is not limited to fixed prosthesis and dental implants, and it is also directed to application for removable prosthesis. The load-bearing ability of zirconia has been shown to be comparable to that of Co-Cr alloy. Ce-TZP/Al₂O₃ nanocomposite (NANOZR) with strength, toughness, and thermal stability comparable or superior to those of previously used yttria-stabilized zirconia (Y-TZP) has been clinically applied, suggesting its applicability as a denture base material substituting for metal.
