PURPOSE
To investigate the impact of software version on the accuracy of an intraoral scanning device.
MATERIALS AND METHODS
A master tooth was scanned with a high-precision optical scanner and then 10 times with a CEREC Omnicam scanner with software versions 4.4.0 and 4.4.4. Discrepancies were measured using quality control software.
RESULTS
Mean deviation for 4.4.0 was 36.2 ± 35 μm and for 4.4.4 was 20.7 ± 14.2 μm (P ≤ .001).
CONCLUSION
Software version has a significant impact on the accuracy of an intraoral scanner. It is important that researchers also publish the software version of scanners when publishing their findings.
目的
研究软件版本对口腔内扫描设备准确性的影响。
材料与方法
用高精度光学扫描仪扫描一颗标准牙齿，然后使用软件版本为4.4.0和4.4.4的CEREC Omnicam扫描仪对其进行10次扫描。使用质量控制软件测量差异。
结果
4.4.0版本的平均偏差为36.2±35μm，4.4.4版本的平均偏差为20.7±14.2μm（P≤.001）。
结论
软件版本对口腔内扫描仪的准确性有显著影响。研究人员在发表研究结果时公布扫描仪的软件版本很重要。
