摘要/Abstract

摘要： 目的通过改良的扫描体增加特征数据点以提高数字化印模的准确性。方法选取牙列缺失种植固定修复患者1名,采用iTero口内扫描获得牙列缺失患者多颗种植体的空间位置信息,通过计算机辅助设计及辅助制造（computer aided design/computer aided manufacturing,CAD/CAM）技术设计制作上部修复体,并在患者口内进行试戴。结果制作的修复体在患者口内实现了被动就位;通过X线片检查,修复基台和切削支架密合。修复12个月后的随访显示,修复体未发生螺丝松动或其他机械并发症,种植体周软硬组织健康。结论基于改良口内扫描获取牙列缺失患者的数字化印模技术,在一定程度上具有替代传统开窗夹板式印模的潜力。

Abstract: Objective: To evaluate the clinical effect of modified intra-oral scan in implantation and restoration of edentulous patients. Methods: The position of multiple implants in an edentulous patient was recorded by modified scan body with extensional structure to increase the accuracy of digital impressions, and the prosthesis was designed and made by computer aided design/computer aided manufacturing(CAD/CAM). Results: The prosthesis made for edentulous patient achieved passive positioning in the mouth. Through X-ray examination, there was no gap between the Uni-abutment and the cutting support. Conclusion: New digital techniques such as modified intra-oral scan technology could provide a reliable alternative to conventional impression.

Key words: digital impression, edentulous, implantation, intra-oral scan, computer aided design/computer aided manufacturing(CAD/CAM)
