The digital way of working is increasingly becoming an indispensable part of dental medicine. The digital impression represents the positive of the hard and soft structures in the patient’s oral cavity. In the digital protocol, digital scanners take the impression. Technological progress has enabled manufacturers to develop highly accurate intraoral scanners that scan the mouth in a couple of seconds or minutes and produce a three-dimensional image on a large screen. These devices are characterized by their scanning speed and ease of manipulation, i.e., the ease with which the device can be moved around the oral cavity during scanning. This procedure is not uncomfortable for the patient and requires less time in the dental chair for the clinician to make accurate impressions. The digital process is unimaginable without computer programs and increasingly artificial intelligence which process the scan, mark potential errors, and allow easier transmission of the scan to the laboratory, making communication faster and easier. The doctor in the office uses these programs to process the scans and create digital models that are saved as files and sent to the system to design a future restoration. Proper preparation of the gingiva for scanning and the scanning technique are both important for the success of the digital impression. The digital impression can also be scanned with a highly accurate extraoral laboratory scanner by scanning analog impressions and models. Scanners are also characterized by their accuracy in scanning, which is defined by two terms, precision and trueness. The aim is to produce devices that have both high values and transmit the information as realistically as possible. With continuous development, the precision of digital scanning is becoming greater and greater, and the digital way of working can be implemented to produce almost all types of prosthetic restorations.
