| Outline of Final Research Achievements |
The biaxial flexure strength of NANOZR was not affected by firing process. From the clinical point of view, the biaxial flexure strength of NANOZR treated by shot-blasting and etching was much higher than 800 MPa, the required flexure strength of substructure ceramic for prostheses involving 4 or more units specified in ISO 6872.Furthermore, the durability over the cyclic load of NANOZR was 106 cycle and 480 MPa or more.As mentioned above, even if NANOZR was densely sintered after machining a Pre-sintered block, having satisfactory biaxial flexure strength and fatigue durability on clinical application as dental prosthetic material was shown.
