取口腔支持组织和固位解剖结构印模所采用的方法。对可摘局部义齿,特别是下颌游离端义齿获得良好的压力分布是十分重要的。作者分析了功能性印模、一次性印模、基托重垫法,粘膜静态技术及应力中断设计等方法的优缺点。提出为使游离端义齿得到合理的负荷分布,必须满足以下3个条件:①基托的组织面,必须与静态牙槽嵴粘膜的表 Oral support tissues and retaining the anatomical structure of the method used. It is important to obtain a good pressure distribution of the removable partial dentures, especially the mandibular free end denture. The authors analyzed the advantages and disadvantages of methods such as functional impression, one-off impression, base-pad method, mucosal static technique, and stress interruption design. It is proposed that in order to obtain a reasonable load distribution of the free end denture, the following three conditions must be met: ① The tissue surface of the base must be matched with the surface of the static alveolar mucosa
