Preparation of mandibular distal-extension removable partial dentures usually requires a secondary impression (the altered-cast impression) to improve the stability of the prosthesis. A potential problem with conventional altered-cast impression procedures is incorrect or incomplete seating of the framework in the mouth or on the cast. This article describes a procedure for obtaining the interjaw relationship and an accurate altered-cast impression in a single appointment (that of the framework try-in).
下颌远中游离端可摘局部义齿的制作通常需要二次印模（改良模型印模）以提高修复体的稳定性。传统改良模型印模程序的一个潜在问题是，支架在口腔内或模型上就位不正确或不完整。本文介绍了一种在一次就诊（即支架试戴就诊）中获取颌间关系和精确改良模型印模的方法。
