摘要/Abstract

摘要： 目的探讨SmartX口内扫描技术在全口种植修复数字印模中的真实度,并比较不同扫描策略对精度的影响。方法将扫描杆分为沿牙槽嵴排列和向心性排列2种,使用配备SmartX的口内扫描仪对All-on 6上颌模型进行扫描,共获取60次扫描（3个模型×2种方法×重复10次）,使用台式扫描仪数据作为对照。通过计算种植体基台之间的距离和角度偏差、均方根误差来评估真实度和精度。结果 SmartX沿牙槽嵴排列扫描策略下基台的距离和角度偏差、均方根误差分别为75.25（45.35,136.40）μm、0.47°±0.22°和88.05（67.75,99.88）μm;SmartX向心性排列扫描策略下基台的距离和角度偏差、均方根误差分别为113.90（81.93,315.60）μm、0.27°±0.18°和93.75 （73.58,98.85）μm,Mann-Whitney U检验和配对样本t检验结果分别显示2种扫描策略下种植体基台精度存在差异（P<0.05）。结论在本研究范围内,2种SmartX扫描策略的距离、角度和均方根偏差低于临床被动就位的可接受范围,扫描策略是影响该系统印模精度的因素之一。

Abstract: Objective To evaluate the trueness of SmartX intraoral scanning (IOS) for full-arch digital implant impressions and to compare the impact of different scanning strategies on accuracy. Methods Scan bodies were arranged in two configurations (along-the-ridge and centripetal) on three all-on-6 maxillary models. SmartX IOS performed 60 scans (3 models × 2 strategies × 10 repetitions). Desktop scanner data served as a reference. IOS scans were compared against reference scans, assessing trueness and precision via distance/angular deviations between implant abutments and root mean square (RMS) errors. Results For along-the-ridge scans: distance deviation = 75.25 (45.35, 136.40) μm, angular deviation = 0.47°±0.22°, RMS = 88.05 (67.75, 99.88) μm. For centripetal scans: distance deviation = 113.90 (81.93,315.60) μm, angular deviation = 0.27°±0.18°, RMS = 93.75 (73.58, 98.85) μm. Mann-Whitney U and paired-samples t-tests indicated significant precision differences between strategies (P<0.05). Conclusion Both SmartX strategies produced clinically acceptable deviations below passive fit thresholds for full-arch digital impressions. Scanning strategy is one of the key factors affecting the impression precision of the system.
