Abstract

With the progress of digital dentistry, the way of prosthesis fabrication has dramatically changed. Since the approval of zirconia in Japan in 2005, CAD/CAM technology capable of processing zirconia has gradually spread. And it accelerated when CAD/CAM crowns were covered by insurance in 2014. As of now, the intraoral scanner attracts worldwide attention, and it is becoming more popular in the self-pay treatment field in Japan, there are increasing opportunities to manufacture prostheses from the intraoral scanner data. In this paper, from the viewpoint of a dental technician, I will describe the differences between the digital method and the conventional one from several perspective.
