Evaluation of the Feasibility of NaCaPO<sub>4</sub>-Blended Zirconia as a New CAD/CAM Material for Dental Restoration
The computer-aided design/computer-aided manufacturing (CAD/CAM) fabrication technique has become one of the hottest topics in the dental field. This technology can be applied to fixed partial dentures, removable dentures, and implant prostheses. This study aimed to evaluate the feasibility of NaCaP...

The computer-aided design/computer-aided manufacturing (CAD/CAM) fabrication technique has become one of the hottest topics in the dental field. This technology can be applied to fixed partial dentures, removable dentures, and implant prostheses. This study aimed to evaluate the feasibility of NaCaPO<sub>4</sub>-blended zirconia as a new CAD/CAM material. Eleven different proportional samples of zirconia and NaCaPO<sub>4</sub> (<i>x</i>Z<i>y</i>N) were prepared and characterized by X-ray diffractometry (XRD) and Vickers microhardness, and the milling property of these new samples was tested via a digital optical microscope. After calcination at 950 °C for 4 h, XRD results showed that the intensity of tetragonal ZrO<sub>2</sub> gradually decreased with an increase in the content of NaCaPO<sub>4</sub>. Furthermore, with the increase in NaCaPO<sub>4</sub> content, the sintering became more obvious, which improved the densification of the sintered body and reduced its porosity.
