“…as scanner calibration, 7 scanning pattern, 8,9 ambient lighting, [10][11][12] extension of the intraoral digital scan, 10,13,14 and operator experience [15][16][17][18] can decrease their accuracy.…”

“…Prior to the start of the study, all operators received clinical IOS training. As confirmed by previous authors, repeated clinical training before the actual treatment decreases the time needed for a digital full arch scan and significantly improves the accuracy of the digital impression [46,47]. In a similar study setup, Zimmerman et al [48] reported that almost all undergraduate students (95%) wanted the CAD/CAM method to be integrated in their regular courses, which is in line of our poll among our operators (95.7% chose digital as preferred impression method).…”

“…For future clinical studies, it could be recommended to run customized training programs for undergraduate students depending on the individual level of skill and the IOS system in use. This might reduce the level of difficulty and the scanning time and might increase the accuracy of the scans [9][10][11][12][13][15][16][17][46][47][48]50].…”

To evaluate the clinical outcomes of resin composite CAD/CAM restorations in a prospective cohort study, and to assess patient and operator satisfaction after restoration placement, 59 indirect resin composite were placed by supervised undergraduate students, of which 43 restorations were followed over a mean period of 28 months (14–44 months) and evaluated using USPHS criteria. Patient and operator satisfaction levels were assessed using a visual analogue scale (VAS) after restoration placement. A total of 37 patients and 47 restorations were included for further study. Four teeth were extracted—three due to extensive drug-induced secondary caries in the same patient, and one tooth due to large periapical periodontitis after 44 months of service. The overall survival rate was 91.4%, and success rate was 87.2%. Differences between baseline and endpoint scores were significant for marginal discoloration (p < 0.05) and adaptation (p < 0.001). Color match (p < 0.05) and surface texture (p < 0.001) differed significantly, affecting all restoration types. VAS scores for patient and operator satisfaction showed a significant rank correlation (p < 0.01), and pairwise comparison showed significant differences for mean overall patient and operator VAS scores (p < 0.001). Lava Ultimate CAD/CAM may be considered a suitable material for overlays and endocrown restorations when combined with IDS, air abrasion, and MDP-containing adhesive systems. Marginal disintegration may present in inlays and onlays over time.

“…Significant differences in scan time or accuracy between CEREC Ortho software and CEREC SW software were observed. When considering material/equipment options for complete‐arch impression techniques, accuracy (trueness and precision) and chair time needed are important attributes 27 . The current study demonstrated that time needed to scan was significantly longer using the Ortho software than the SW software (∼1 minute difference).…”

Purpose The purpose of this in vitro study was to evaluate the effect of software on scan time, trueness, and precision of digital scans created using the CEREC Omnicam. Material and methods Sixty scans (20 scans/provider) of a standard reference cast were made by three different providers using the CEREC Omnicam with both CEREC Ortho 1.2.1 software (10 scans/provider) and CEREC SW 4.4.4 software (10 scans/provider). A digital full arch scan and the time to complete each scan were recorded. Trueness was calculated by overlaying the digital scans against a reference file created using the standard reference cast and a laboratory‐based, white light, 3‐dimensional scanner. Precision was calculated by overlaying each of digital scans against each other, using each scan as a reference. The non‐parametric Mann‐Whitney U‐test was used to determine significant differences attributable to scanning software for each provider. Results The CEREC Ortho 1.2.1 software required a longer scan time than the CEREC SW 4.4.4 software for each provider (∼1 minute). No significant difference in trueness was observed within one provider. Two individual providers had higher precision when scanning with the CEREC Ortho 1.2.1 software than the CEREC SW 4.4.4 software. Conclusion Software and scan strategy may affect the accuracy of complete‐arch scans. The CEREC Ortho 1.2.1 software may demonstrate a speed‐accuracy tradeoff, with generally longer scan times and possibly more precise scans.
