Purpose: The objective was to provide a comprehensive systematic review about the accuracy of digital implant impression in comparison with the conventional implant impression approach.
Materials and methods: PubMed, Google Scholar and Cochrane databases were used to classify the related articles with no year limitation in 3 stages by 2 reviewers. Finally, 10 articles were included based on inclusion and exclusion criteria.
Results: Five articles supported the use of intraoral scanners in implant dentistry. The two in vivo pilot studies showed that digital scanning is not reliable and could not be used in clinical routine.
Conclusion: Because each study included in this review has its unique methodology and design, it is therefore early to conclude whether to use digital scanners for clinical practice or not. More well-conducted in vitro and clinical trials studies are recommended to investigate the accuracy of intraoral scanners.
