本研究的目的是测量数字印象（DI）与传统印象（CI）相比的准确性。使用iTero系统，扫描母模以生产立体光刻模具。作为对照组，取硅胶印模并使用石头浇注。将得到的立体光刻和石模扫描并叠加在主铸件的扫描参考图像上。DI和CI与主铸件的平均（+/-标准差）尺寸差异分别为23.9（+/- 17.6）μ m和17.6（+/- 45.6）μ m。结果表明，DI也为临床应用提供了足够的准确性。国际修复牙学杂志2013;26：161-163。doi：10.11607/ijp.3014
The purpose of this investigation was to measure the accuracy of digital impressions (DIs) compared to conventional impressions (CIs). Using the iTero system, a master cast was scanned to produce stereolithography dies. As a control group, silicone impressions were taken and poured using stone. The resulting stereolithography and stone dies were scanned and overlayed on the scanned reference image of the master cast. The mean (+/- standard deviation) dimensional difference to the master cast was 23.9 (+/- 17.6) mu m for DIs and 17.6 (+/- 45.6) mu m for CIs. The results indicate that DIs also provides enough accuracy for clinical application. Int J Prosthodont 2013;26:161-163. doi: 10.11607/ijp.3014
