To evaluate the trueness of two intraoral scanners in different clinical situations and considering operator experience.
Two intraoral scanner systems were used to perform a total of 120 digital impressions of three master casts reproducing three scenarios (single implant, two implants, and four implants [full-arch]). Two operators, one experienced and one unexperienced, were selected.
No differences were found between the two operators. A statistically significant correlation was found with regard to the scanning system used and the clinical scenario analyzed.
Within the limits of this preliminary report, operator experience seems not able to significantly influence the trueness of a digital impression; however, imprecision increased in the full-arch cases for both operators. The twoimplant scenario presented similar trueness values for both scanner systems.
评估两种不同临床情况下和考虑操作者经验的口内扫描仪的准确性。
使用两种口内扫描仪系统对三个复制三个场景（单个种植体、两个种植体和四个种植体[全口]）的上颌模型进行总共 120 次数字印模。选择了两位操作者，一位有经验，一位无经验。
两位操作者之间没有差异。在分析的扫描系统和临床场景方面，发现了具有统计学意义的相关性。
在本初步报告的限制范围内，操作者经验似乎不能显著影响数字印模的准确性；然而，对于两位操作者，全口病例的不精确性都增加了。两种扫描系统在两个种植体场景下都具有相似的准确性。
