At present, the evidence regarding digital impressions' accuracy recorded by using digital scanners is lacking. This systematic review aimed to evaluate whether the type of scanning (intraoral/extraoral) affects the Accuracy of Digital Impressions.
Two independent reviewers performed a systematic search in the database both electronically and manually (PubMed, Ebsco HOST, the Cochrane Library, and Google Scholar) for articles published from 1 January 2010 to 1 December 2022. This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO CRD42020188765) and followed the PRISMA statement. The question in focus was as follows: Does the type of scanning (intraoral or extraoral) affect the accuracy of digital impression?
A total of 449 papers were obtained by searching electronically and manually. In total, 15 complete-text papers qualified for assessment based on eligibility criteria. After reading the full-text articles, five studies were excluded. Ten studies were selected for the qualitative analysis. The qualitative data reported that the accuracy of both types of scanners (intraoral and extraoral) lies within the range of clinical acceptability. Nevertheless, the intraoral scanners seem to be more accurate when compared to the extraoral scanners for a partial arch situation.
Scanning type affects the accuracy of the digital impression. Various factors influence the scanning ability. Intraoral scanners seem to be more accurate compared to extraoral scanners for a partial arch situation. More studies comparing the accuracy of the intraoral scanner and extraoral scanner for a complete arch scan and in an in vivo study setting are needed.
目前，关于使用数字扫描仪记录的数字印模准确性的证据不足。本系统评价旨在评估扫描类型（口内/口外）是否会影响数字印模的准确性。
两名独立 reviewers 通过电子和手动方式在数据库（PubMed、Ebsco HOST、Cochrane 图书馆和谷歌学术）中检索 2010 年 1 月 1 日至 2022 年 12 月 1 日发表的文章。本研究在国际前瞻性系统评价注册库（PROSPERO CRD42020188765）注册，并遵循 PRISMA 声明。重点关注的问题如下：扫描类型（口内或口外）是否会影响数字印模的准确性？
通过电子和手动检索共获得 449 篇论文。根据纳入标准，共有 15 篇全文论文符合评估条件。阅读全文后，排除了 5 项研究。选择 10 项研究进行定性分析。定性数据表明，两种类型的扫描仪（口内和口外）的准确性均在临床可接受范围内。然而，对于部分牙弓情况，与口外扫描仪相比，口内扫描仪似乎更准确。
扫描类型会影响数字印模的准确性。多种因素会影响扫描能力。对于部分牙弓情况，与口外扫描仪相比，口内扫描仪似乎更准确。需要更多比较口内扫描仪和口外扫描仪在全牙弓扫描及体内研究环境下准确性的研究。
