“…The CAD/CAM process manufactures dental prostheses in the order of scanning, CAD, and CAM processes [7,8]. The steps of CAD/CAM workflow are as follows: acquire a virtual work model using a 3-dimensional (3D) scanner and produce a working cast using a 3D printer, milling machine, or design a prosthesis in CAD software without a model and then use 3D printing and milling technologies to fabricate dental prostheses [9,10].…”

This study aimed to evaluate the intaglio surface trueness of interim dental crowns fabricated with three 3-dimensional (3D) printing and milling technologies. Dental crown was designated and assigned as a computer-aided design (CAD) reference model (CRM). Interim dental crowns were fabricated based on CRM using two types of 3D printer technologies (stereolithography apparatus and digital light processing) and one type of milling machine (n = 15 per technology). The fabricated interim dental crowns were obtained via 3D modeling of the intaglio surface using a laboratory scanner and designated as CAD test models (CTMs). The alignment and 3D comparison of CRM and CTM were performed based on the intaglio surface using a 3D inspection software program (Geomagic Control X). Statistical analysis was validated using one-way analysis of variance and Tukey HSD test (α = 0.05). There were significant differences in intaglio surface trueness between the three different fabrication technologies, and high trueness values were observed in the milling group (p < 0.05). In the milling group, there was a significant difference in trueness according to the location of the intaglio surface (p < 0.001). In the manufacturing process of interim dental crowns, 3D printing technologies showed superior and uniform manufacturing accuracy than milling technology.

“…[3][4][5][6][7][8][9] Arch width Arch width or intermolar distance In general, the higher the intermolar width, the lower the intraoral scanning accuracy. 7,10,12 Palate Addition or not of the palate in the maxillary intraoral digital scan Higher accuracy values have been reported when the palate is not included in the maxillary intraoral digital scan. 12 Wetness The presence of humidity on the intraoral tissues being digitized Wetness difficult the digitizing procedure reducing intraoral scanning accuracy.…”

“…7 In the i500 system, the narrowest and broadest intermolar widths tested obtained the highest scanning discrepancies. 10 In a clinical study, Gan et al 12 assessed the influence of arch width on the accuracy of maxillary intraoral digital scans. Trueness scanning discrepancies were not found with variations in arch width; however, the scanning precision of the intraoral digital scans decreased with increased arch width.…”

“…Dental arch width variation has been identified as an intraoral patient condition that can impact intraoral scanning accuracy. 8,[10][11][12] In 2020, an in vitro study measured the influence of different volumetric dimensions of maxillary casts on the scanning accuracy of three IOSs (CS 3600 from Carestream, Trios 3 from 3Shape A/S, and i500 from Medit). 10 The intermolar width tested ranged from 38.45 to 71.09 mm.…”

Objectives: To describe the factors related to patient intraoral conditions that impact the scanning accuracy of intraoral scanners (IOSs). A new classification for these influencing factors is proposed to facilitate dental professionals' decision-making and maximize the accuracy and reliability of intraoral digital scans.Overview: Variables related to intraoral conditions of the patient that can influence the scanning accuracy of IOSs include tooth type, presence of interdental spaces, arch width variations, palate characteristics, wetness, existing restorations, characteristics of the surface being digitized, edentulous areas, interimplant distance, position, angulation, and depth of existing implants, and implant scan body selection. Conclusions:The knowledge and understanding of the patient's intraoral conditions that can impact the scanning accuracy of IOSs is a fundamental element for maximizing the accuracy of IOSs.
