In recent years, many clinicians have abandoned the time-consuming and technique-sensitive border-molded custom impression in favor of a simplified stock tray and irreversible hydrocolloid final impression. However, the master cast obtained by this simplified method often will lead to a completed prosthesis that has inadequate support from the distal extension tissue areas. This article presents a simple, predictable, clinically effective, and readily learned functional bilaminar impression technique that will allow dentists to make an anatomically and functionally supported distal extension removable partial denture.
近年来，许多临床医生已摒弃耗时且对技术要求高的边缘整塑定制印模，转而采用简化的成品托盘和不可逆水胶体终印模。然而，通过这种简化方法获得的主模型常常会导致最终修复体在远中延伸组织区域缺乏足够的支持。本文介绍一种简单、可预测、临床有效的且易于掌握的功能性双层印模技术，该技术能让牙医制作出在解剖结构和功能上均得到支持的远中延伸可摘局部义齿。
