“… 58 Ultimately, 55 documents were included in the qualitative analysis.

PURPOSE This study aimed to investigate whether the accuracy of intraoral scanners is influenced by different scanning strategies in an in vitro setting, through a systematic review and meta-analysis. MATERIALS AND METHODS This review was conducted in accordance with the PRISMA 2020 standard. The following PICOS approach was used: population, tooth impressions; intervention, the use of intraoral scanners with scanning strategies different from the manufacturer’s instructions; control, the use of intraoral scanners following the manufacturers’ requirements; outcome, accuracy of intraoral scanners; type of studies, in vitro . A comprehensive literature search was conducted across various databases including Embase, SciELO, PubMed, Scopus, and Web of Science. The inclusion criteria were based on in vitro studies that reported the accuracy of digital impressions using intraoral scanners. Analysis was performed using Review Manager software (version 5.3.5; Cochrane Collaboration, Copenhagen, Denmark). Global comparisons were made using a standardized mean difference based on random-effect models, with a significance level of α = 0.05. RESULTS The meta-analysis included 15 articles. Digital impression accuracy significantly improved under dry conditions ( P < 0.001). Moreover, trueness and precision were enhanced when artificial landmarks were used ( P ≤ 0.02) and when an S-shaped pattern was followed ( P ≤ 0.01). However, the type of light used did not have a significant impact on the accuracy of the digital intraoral scanners ( P ≥ 0.16). CONCLUSION The accuracy of digital intraoral scanners can be enhanced by employing scanning processes using artificial landmarks and digital impressions under dry conditions.

“…Both the prosthetic abutments and the definitive crowns were designed without altering the same work protocol in order to obtain the same result in all cases, even in cases where there may have been implants with angulations that could require corrections. Although there are studies indicating that the process of overlaying titanium custom abutments with pre-scan custom abutment library data improves the accuracy of the digital scan performed with respect to an intraoral scan, there was no risk of bias because all cases were scanned with the same scanning abutment [ 33 , 34 ]. Studies have shown that the use of customised abutments leads to an increase in the final abutment size, improved retention of the prosthetic work, and reduced angulation of the abutment in relation to the implant axis, thus reducing the risk of unscrewing or fracturing the dental screw.…”

Background: The objective of this study was to evaluate the pain and inflammatory response in soft tissues using healing and prosthetic abutments of different diameters and lengths. Methods: The study population was rehabilitated with Astra Tech EV single implants (Dentsply Sirona, Atlantis, Dentsply Sirona S.A., Barcelona, Spain) of 4.2 and 4.8 millimetres in diameter in the upper and lower maxilla and loaded with custom abutments digitally designed using Dentsply Sirona’s Virtual Atlantis Design software (Atlantis WebOrder, Dentsply Sirona S.A., Barcelona, Spain), version 4.6.5. The custom abutments had a larger diameter than the healing abutments to evaluate for biomarkers through ELISA. Results: Rehabilitations in the mandible and with healing abutments with diameters less than 4.29 mm and rehabilitators with diameters less than 2.18 mm elicited a higher pain and inflammatory response and, in turn, higher interleukin-1β values. Conclusions: Greater inflammation was evident in cases in which healing abutments with reduced diameter were used compared to the same subsequent rehabilitation with prosthetic abutments with larger diameters.
