摘　　要：采取印模是制作全口义齿的第一步,是成功修复全口义齿的关键。准确的全口印模要精确地反映无牙颌患者剩余牙槽嵴的解剖形态和周围组织生理功能活动范围,以便使义齿基托与口腔黏膜高度密合,获得良好的边缘封闭,从而取得全口义齿良好的固位,并能在功能运动时保持稳定。越来越多的研究表明,传统的印模方法已不能满足临床要求。近年来各种改良式印模方法层出不穷,如:开窗托盘印模法、动态压力式印模法、后缘截断框架式托盘印模法及中性区技术等,这些方法在取组织面、磨光面或黏膜转折处的印模上各有优势或侧重。针对不同的患者,应根据其剩余牙槽嵴条件、全身情况或修复需求等情况而选择相应的印模方法。本文就无牙颌取模技术的不同侧重角度、技术要点、适应证等方面作一综述。Taking impressions is the first step and the key to complete denture fabrication. An accurate impression of edentulous jaws must precisely reflect the anatomical shape and movement of the residual ridge and adjacent oral structures. Accurately increasing the border seal, retention, and comfort of the complete denture, as well as maintaining its stability during oral functional movements, is important. Numerous studies have shown that traditional impression methods are unable to meet the clinical requirements. Various modified impression methods, such as window tray, dynamic functional impression, frame cut back tray, and neutral zone techniques, etc., have continuously emerged in recent years. In the author’s opinion, the most suitable technique for taking impressions should be chosen based on the different residual alveolar ridge shapes, general conditions, or oral rehabilitation demands. This article reviews the various complete denture impression techniques and focuses on their corresponding technical key points and clinical applications.
