摘要: 印模的精度与全牙弓种植固定修复体的被动就位密切相关,并影响其长期效果。传统开窗印模技术在全口种植修复中具有较高的精度,被视为金标准。随着数字化技术的不断发展,立体摄影测量技术(stereophotogrammetry,SPG)目前已应用于全口种植的数字化印模制取。与传统开窗印模技术相比,SPG具有椅旁时间短、患者舒适度高、操作流程简化等优势,但其精度尚存争议。本文就SPG的原理与使用方法、体内外研究与应用、印模精度的影响因素等进行综述,以期能为SPG的发展提供参考依据。

Abstract: The accuracy of impressions is closely related to the passive fit of complete-arch implant-supported prostheses, which significantly affects their long-term outcomes. Conventional open-tray impression techniques have been recognized for their high accuracy in full-arch implant restorations and are still regarded as the gold standard. However, with the ongoing advancements in digital technology, stereophotogrammetry (SPG) has been introduced for digital impression-making in complete-arch implant cases. Compared to the traditional open-tray technique, SPG offers advantages such as reduced chair time, increased patient comfort, and a simplified workflow. Despite these benefits, the accuracy of SPG remains a topic of debate. This article reviews the principles and methods of SPG, its in vivo and in vitro applications, and factors influencing impression accuracy, to provide a reference for further development of SPG in implant dentistry.
