摘要
无牙颌种植体支持修复可有效改善传统全口义齿的固位和稳定,提高患者的咀嚼功能.上部结构的被动就位对种植修复的长期成功率极为重要,而印模的精度与被动就位状态密切相关.无牙颌种植修复印模制取方法主要包括传统印模方法和数字化印模方法.随着数字化技术的发展,数字化印模因可简化取模流程、方便沟通设计及提高患者舒适度等优势而被逐渐应用于无牙颌种植修复中,但其印模精度尚不明确.文章就无牙颌种植修复印模制取方法做一阐述,并对印模精度的影响因素和评价方法及不同制取方法的精度进行论述,以提高临床医生的无牙颌种植修复印模制取技术水平.
Abstract
Compared to conventional complete denture,complete-arch implant-supported restoration provides improved fixation and stability,enhancing the masticatory efficiency of patients.Passive fit of the upper structure is critical to long-term success,which is closely related to impression accuracy.The main impression methods for complete-arch implant-supported restorations include conventional impression methods and digital impression methods.With the continuous de-velopment of digital technology,digital impressions are increasingly employed in edentulous patients due to their advan-tages of simplifying the impression-taking process and facilitating communication and design,as well as improving pa-tient comfort;however,the accuracy of the impression remains uncertain.This article reviews the impression methods for complete-arch edentulous patients and some factors affecting the impression accuracy,aiming to increase clinicians'lev-el in impression of edentulous implant-supported restoration.
