SmartX不同扫描策略在全口种植修复数字印模中的精度比较研究
Comparative study on the accuracy of different SmartX scanning strategies in full-arch implant prosthetic digital impressions
摘要
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.关键词
