“…[43][44][45] Studies have analyzed the influence of the implant depth on intraoral scanning accuracy with contradictory results reported. [43][44][45] In an in vitro study, Laohverapanich et al 43 when obtaining a half-arch scan on a partially edentulous cast with 1 implant scan body. The best accuracy values were obtained when implants had up to 6-mm depth.…”

“…Implant depth is related to clinical implant scan body height 43–45 . Studies have analyzed the influence of the implant depth on intraoral scanning accuracy with contradictory results reported 43–45 . In an in vitro study, Laohverapanich et al 43 evaluated the influence of the implant depth (3, 6, and 9 mm) on the scanning accuracy of four IOSs (Omnicam from Dentsply Sirona, Trios 3 from 3Shape A/S, True Definition from 3 M ESPE, and DWIO from Dental Wings) when obtaining a half‐arch scan on a partially edentulous cast with 1 implant scan body.…”

“…The best accuracy values were obtained when implants had up to 6‐mm depth 43 . Similarly, Sequeira et al 45 evaluated the influence of the implant depth (7, 6, 3, and 0 mm) on the accuracy of half‐arch implant digital scans acquired by using an IOSs (CS3600 from Carestream). The cast selected had a single implant scan body.…”

“…45 • Contradictory results have been reported regarding the influence of implant angulation on intraoral scanning accuracy. [36][37][38][39][40][41][42][43][44][45] Some studies concluded that implant angulation decreased the scanning accuracy of IOSs, 36,39,41,42,45 while other studies have shown that implant angulation had no effect on intraoral scanning accuracy. 37 • Contradictory results have been reported regarding the influence of implant depth on the accuracy of IOSs.…”

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.

“…Similarly, complete‐arch scans by using IOSs for fabricating complete‐arch tooth‐ and implant‐supported rehabilitations have shown contradictory results in the literature regarding reliability and accuracy 31–35,41,42 . Different techniques have been described to improve the scanning accuracy of complete‐arch implant digital scans; however, due to the limited clinical data published, a systematic recommendation of complete‐arch implant digital scans by using IOSs is difficult 43–45 …”

Objectives To describe the factors related to the operator skills and decisions that influence the scanning accuracy of intraoral scanners (IOSs). A new classification for these factors is proposed to facilitate dental professionals' decision making when using IOSs and maximize the accuracy and reliability of intraoral digital scans. Overview Each IOS system is limited by the hardware and software characteristics of the selected device. The operator decisions that can influence the accuracy of IOSs include the scanning technology and system selection, scanning head size, calibration, scanning distance, exposure of the IOS to ambient temperature changes, ambient humidity, ambient lighting conditions, operator experience, scanning pattern, extension of the scan, cutting off, rescanning, and overlapping procedures. Conclusions The knowledge and understanding of the operator factors that impact scanning accuracy of IOSs is a fundamental element for maximizing the accuracy of IOSs and for successfully integrating IOSs in daily practices. Clinical Significance Operator skills and clinical decisions significantly impact intraoral scanning accuracy. Dental professionals must know and understand these influencing operator factors for maximizing the accuracy of IOSs.

ObjectivesLimited studies are available on the accuracy of intraoral scanners (IOSs) for full‐arch implant and tooth models. This study aimed to assess the accuracy of maxillary full‐arch digital impressions of tooth and implant models made by two IOSs.Materials and MethodsThis in vitro, experimental study was conducted on two maxillary dentiform models: one with six prepared natural teeth and the other with six implants at the site of canine, first premolar, and first molar teeth, bilaterally. A highly accurate industrial scanner was used for actual measurements on the models that served as the reference scan. TS (Trios3) and CO (CEREC Omnicam) IOSs were then used to scan each model 10 times according to the manufacturer's instructions. All scans were saved in STL format. The GOM Inspect software was used according to the best‐fit algorithm to compare the accuracy of measurements in the groups with the reference scan. The trueness and precision were calculated. Statistical analyses were carried out using SPSS by one‐way analysis of variance and t‐test (α = .05).ResultsTS showed a significantly higher trueness than CO for both tooth and implant models (p < .05). TS also revealed significantly higher precision than CO for the tooth model; however, the difference in precision for the implant model was not significant between the two IOSs (p > .05).ConclusionsTS showed higher accuracy than CO in both tooth and implant models.
