(1) Background: Intraoral scanners (IOS) are widely used in prosthodontics. However, a good trueness is mandatory to achieve optimal clinical results. The aim of the present in vitro study was to compare two IOS considering the operator's experience and different implant clinical scenarios. (2) Methods: Two IOS (IT-Itero, Align Technology; and OP-Opera MC, Opera System, Monaco) were compared simulating three different clinical scenarios: single implant, two implants, and full-arch rehabilitation. Ten scans were taken for each configuration by two different operators (one expert, one inexperienced); influence of operator experience and the type of scanner used was investigated. (3) Results: Trueness of the scans differed between the experienced and non-experienced operator and this difference was statistically significant in all the three scenarios ( = 0.000-0.001, 0.037). A significant difference was present between the scanners ( = 0.000), in the two-implant and full-arch scenarios ( = 0.00). (4) Conclusions: Experience of the operator significantly affect trueness of IT and OP scanners. A statistically significant difference was present among IOS in the two-implant and full-arch scenarios.
(1) 背景：口腔内扫描仪（IOS）在口腔修复学中被广泛使用。然而，要获得最佳临床效果，良好的精度是必不可少的。本体外研究的目的是考虑操作者的经验和不同的种植临床情况，比较两种IOS。(2) 方法：比较两种IOS（IT-Itero，Align Technology公司；和OP-Opera MC，Opera System公司，摩纳哥），模拟三种不同的临床情况：单颗种植体、两颗种植体和全牙弓修复。由两名不同的操作者（一名专家，一名经验不足者）对每种配置进行十次扫描；研究操作者经验和所用扫描仪类型的影响。(3) 结果：经验丰富和经验不足的操作者扫描的精度存在差异，并且在所有三种情况下这种差异具有统计学意义（P = 0.000 - 0.001，0.037）。在两颗种植体和全牙弓情况下，扫描仪之间存在显著差异（P = 0.000）（P = 0.00）。(4) 结论：操作者经验显著影响IT和OP扫描仪的精度。在两颗种植体和全牙弓情况下，IOS之间存在统计学上显著的差异。
