Abstract: Abstract：Objective To compare the effect of two ways’ impressions in edentulous jaws prosthodontics：jaw-closing impression and jaw-opening impression. Methods Thirty cases of complete denture patients were chosen， and randomly divided into two groups；complete dentures were made by jaw-closing impression and jaw-opening impression respectively， then the adsorbability and sore spots modifications were checked after three months. Results The adsorbability of complete denture fabricated with jaw-closing impression technique was better and the times of sore spots amendment were less. Conclusion In fabrication of complete denture， jaw-closing impression technique with silicone rubber materials is better than jaw-opening impression technique.

摘要： 目的 比较硅橡胶闭口式印模法和开口式印模法在无牙颌义齿修复中的临床疗效。方法 收集2008年3月至2011年9月福建医科大学附属第一医院口腔科收治的无牙颌修复患者30例，按初诊时间顺序随机分为闭口式印模组和对照组，分别使用闭口式和开口式印模法制作全口义齿，3个月后复查其吸附力和压痛修改情况。结果 用闭口式印模法制作的全口义齿，吸附力好于开口式印模法，其压痛修改次数也明显减少。结论 对于无牙颌全口义齿的制作，硅橡胶闭口式印模法优于开口式印模法。
