Abstract :
With the popularization of digital technology and the exposure of traditional technology’s defects, computer-aided design andcomputer-aided manufacturing (CAD/CAM) has been widely used in thefield of dentistry. and the accuracy of the scanningsystem determines the ultimate accuracy of the prosthesis, which is a very important part of CAD/CAM, so we decided toevaluate the accuracy of the intraoral and extraoral scanners. In this study, we selected the sphere model as the scanning objectand obtained thefinal result through data analysis and 3Dfitting. In terms of trueness and precision, the scanner of SHININGwas significantly different from that of others; however, there was no significant difference between TRIOS and CEREC.SHINING showed the lowest level of accuracy, with CEREC slightly lower than TRIOS. The sphere model has also been provento be scanned successfully.
