“…Nestler et al, who explained the causes of deviations that occur during printing, compared photopolymerization-based and extrusion-based systems and reported that shrinkage and warpage were caused by incomplete polymerization of the resin monomer by light sources during printing. It was explained that DLP showed superior trueness compared with other printers because of better polymerization of resin [ 5 , 9 , 18 ]. Gjelvold et al assessed deviations between the positions of surgical guides for computed tomography implant surgery fabricated by desktop 3D printers based on two different techniques (DLP and SLA).…”

“…Gjelvold et al assessed deviations between the positions of surgical guides for computed tomography implant surgery fabricated by desktop 3D printers based on two different techniques (DLP and SLA). They reported that the SLA technique showed a slightly higher deviation in specific parts of the guide, as compared to the DLP technique, and presented the cause of the difference between the mean deviation of the dental implant position [ 18 ]. Other studies reported that one of the advantages of DLP and SLA printers was less shrinkage as compared to other 3D technologies, including FDM [ 16 , 31 , 38 , 39 ].…”

“…Various types of 3D structures could be fabricated using STL data obtained from IOS, and various dental devices could be fabricated with 3D printers. However, there is a lack of studies on IOS based on which principle and what type of 3D printers have high compatibility and are superior [ 9 , 10 , 18 ]. Therefore, it is necessary to study whether accurate results could be obtained through print tests using data obtained from IOS printed using various types of 3D printers.…”

“…In contrast, SM, which is also referred to as milling, involves cutting a block to the desired shape. Compared to SM, such as milling hard ceramic, AM, which lacks resolution and accuracy, can be used to produce complex structures without wasting material unlike SM where material is discarded after being cut [ 4 , 5 , 18 , 19 , 31 ].…”

To assess the accuracy of various intraoral scanners (IOSs) and to investigate the existence of mutual compatibility that affects the accuracy between IOS and 3-dimensional (3D) printing using a scan quadrant model. For clinical implication, crown preparations and cavity design according to prosthetic diagnosis and treatment considerations must be acquired by a digital scanner. The selected typodont model was scanned using a reference scanner, from which reference (Ref) standard tessellation language (STL) data were created. Data obtained by scanning the typodont model with IOSs based on three different technologies were divided into three groups (CS3600, i500, and Trios3). Scanned data from the groups were divided into sub-groups of digital light processing (DLP), fused deposition modeling (FDM), and stereolithography apparatus (SLA), based on which 3D printed models (3DP) were fabricated. The 3DP dental models were scanned to obtain a total of 90 3DP STL datasets. The best-fit algorithm of 3D analysis software was used for teeth and arch measurements, while trueness was analyzed by calculating the average deviation among measured values based on superimposition of Ref and IOS and 3DP data. The differences between Ref and IOS (Ref-IOS), Ref and 3DP (Ref-IOS/3DP), and IOS and 3DP data (IOS-3DP) were compared and analyzed, while accuracy within each of the three main groups was assessed. For statistical analysis, the Kruskal–Wallis, Mann–Whitney U, and repeated measures ANOVA test were used (p < 0.05). The major finding is that the mutual relationships between IOSs and 3D printers vary depending on the combination. However, i500 intraoral scanner and DLP 3D printer was the combination that showed the best trueness value.
