A two-stage impression technique that uses polyvinyl siloxane and irreversible hydrocolloid in a custom impression tray is described. The technique records the tissues to be contacted by the facial prosthesis with minimal distortion with the patient in an upright position and facial musculature at rest. The procedure is simple, accurate, and it eliminates some of the shortcomings of other techniques.
本文描述了一种两阶段印模技术，该技术在定制印模托盘上使用聚乙烯基硅氧烷和不可逆水胶体。该技术在患者直立且面部肌肉处于静止状态时，能以最小的变形记录面部假体将要接触的组织。该操作简单、准确，并且消除了其他技术的一些缺点。
