Intraoral scanners (IOSs) are used for capturing the direct optical impressions in dentistry. The development of three-dimensional technology and the trend of increasing the use of IOSs in dental office routine lead to the need to assess the accuracy of intraoral digital impressions. The aim of this review was to assess the accuracy of the different IOS and the effect of different variables on the accuracy outcome. An electronic search using PubMed with specific keywords to obtain potential references for review. A search of MEDLINE (PubMed) identified 507 articles. After title and abstract screening, 412 articles were excluded for not meeting the inclusion criteria and discarding duplicate references. Ninety-five articles were followed for full screening; only 24 articles were included in the final analysis. The studies indicated a variable outcome of the different IOS systems. While the accuracy of IOS systems appears to be promising and comparable to conventional methods, they are still vulnerable to inaccuracies.
口腔内扫描仪（IOSs）用于在牙科领域获取直接的光学印模。三维技术的发展以及在牙科诊所日常工作中越来越多地使用IOSs的趋势，导致需要评估口腔内数字印模的准确性。本综述的目的是评估不同IOS的准确性以及不同变量对准确性结果的影响。通过使用PubMed并使用特定关键词进行电子搜索，以获取潜在的综述参考文献。对MEDLINE（PubMed）的搜索识别出507篇文章。在标题和摘要筛选后，412篇文章因不符合纳入标准和丢弃重复参考文献而被排除。95篇文章进行了全文筛选；最终分析仅纳入24篇文章。研究表明不同IOS系统的结果存在差异。虽然IOS系统的准确性似乎很有前景且与传统方法相当，但它们仍然容易出现不准确的情况。
