摘要:: [摘要]目的：比较使用口内扫描法和传统硅橡胶法制取种植磨牙单冠的临床修复效果评价。方法：选择62例患者（共86颗后牙），随机分为试验组和对照组，每组43颗牙（其中前磨牙13颗，磨牙30颗）。临床分别采用硅橡胶法和口内扫描法制取印模，制作氧化锆全瓷修复体，于治疗后2周复诊，采用VAS评分量表及改良的美国公共卫生总署（United states public health service,USPHS）评价系统对修复效果及舒适度进行评价。结果：口内扫描法组的患者满意度更高，舒适度更好，两组 USPHS评分中除口内扫描组修复体的边缘适合性A级比例比对照组高外，其余指标的A级比例差异无统计学意义（P＞0.05）。结论：口内扫描技术应用在种植磨牙单冠的印模制作中，修复效果良好、精度高外，患者满意度高，值得临床推广应用。

Abstract:: Abstract: Objective To compare the difference of restoration effects between digital intraoral scanning technology and conventional impression of silicon rubber for implant restoration of the posterior teeth.Methods In this study,62 patients undergoing implant restorations for the posterior teeth were enrolled.43 patients accepted 3Shape intraoral scan to get digital impressions(direct group),while 43 patients were treated by conventional impression technology(control group).A satisfaction survey and VAS value scale was conducted after treatment for 2 weeks.The check and evaluation were conducted according to the adapted USPHS standards after treatment.Results The patients in the oral scanning group were more satisfi ed and more comfortable. In the USPHS score of the two groups, except for the A-level ratio of marginal fi tness of the prosthesis in the oral scanning group was higher than that in the control group, there was no signifi cant diff erence in the A-level ratio of other indicators (P＞0.05). Conclusion The application of intraoral scanning technology in the preparation of implant restoration has good repairing eff ect,high precision and high patient satisfaction.It is worth popularizing in clinic.
