Comparison of accuracy of current ten intraoral scanners
In recent decades, there has continuous advancement in digital technologies in dentistry, such as computer-aided design/computer-aided manufacturing (CAD/CAM) systems, milling systems, three-dimensional (3D) scanning, and printing of various dental biomaterials (1-3). Digital dentistry helps in the diagnosis, treatment planning, and fabrication of prostheses. An accurate dental impression is required to fabricate a good dental prosthesis or restoration (4, 5). To fabricate a prosthesis or restoration digitally, dentists send the digital impression obtained from an intraoral scanner (IOS) from the clinic to the dental laboratory. Then, after receiving the digital scan, the dental technician creates a digital model, then designs, and finally manufactures the prosthesis.
There are different IOSs that are available in the market (6). Intraoral scanners generally have a scan area of 1-2 teeth (7, 8). At present, there are advanced scanning technologies, such as triangulation technique (used by Cerec, Dentsply Sirona), active wavefront sampling (used by True Definition, 3 M ESPE), and confocal scanning technique (used by iTero, Align Technology, and Trios, 3Shape) (9-11). The confocal scanning technology is a faster scanning technology that captures images by focusing on an optical light beam with high-resolution visual images with improved accuracy and fewer distortions (9, 12).
Hence, with the various developments in intraoral 3D scanning technology, it is important to [...]
