Study Notes

Digital dentistry workflow includes implant planning, patient CAD-CAM intra-oral scanner, CBCT guide fabrication, and production equipment
Workflow of digital dentistry includes digitization acquisition equipment and processing, point cloud data, and rendered data
Accuracy in digital dentistry is defined as both trueness and precision
Trueness is the comparison between a reference data set and a test data set (scan), while precision is the comparison between various data sets obtained from the same object
For single unit dentistry, anatomy of the scanned object, angulation, and scan technique are important factors affecting accuracy
For full arch scans, an increase in distance and/or angular errors can be observed due to registration errors of patched 3D surfaces
Mean trueness and precision values for full arch scans vary between different systems, with some showing higher deviations than others
Intraoral scanners have lower precision at greater distances between scanbodies, while desktop scanners maintain consistent precision regardless of distance
Single unit restorative facial scan preparation involves sequential scanning of various quadrants and correct stitching of data for full arch restoration.
