目的分析评估用硅橡胶二次印模法制取上前牙印模中的龈沟残留材料情况，为临床安全使用硅橡胶印模材料提供指导。方法对135颗拟行固定修复的上前基牙使用硅橡胶二次印模法制取印模后，观察并记录印模基牙龈沟翼缺损数，并依次用以下两种方法检查口内基牙龈沟中硅橡胶印模材料残留情况：A：采用肉眼直视下观察基牙龈沟，B：在5倍放大镜下继续用刮治器探寻基牙龈沟；分别记录材料残留数量与位置。结果135颗上前牙印模在肉眼直视下见24颗印模翼缘缺损，口内直视观察发现9颗基牙龈沟硅橡胶残留，继续放大镜下用刮治器探查，又发现13例龈沟深部残留。结论硅橡胶印模龈沟残留现象比较常见且容易被忽略，应引起临床医师的的高度重视，印模后应常规使用刮治器械探查龈沟内是否有印模材料的残留现象。

Objective: To evaluate the incidence rate of silicone rubber impression material remaining in the gingival crevice after removal of the set impression. Methods: A total of 135 anterior abutment teeth were prepared for complete coverage restorations. Curette were used to find the remaining pieces of impression material with a forehead type magnifying glass. Results:An inspection of the impression after removal, revealed defect in the sulcus region of 24 teeth. Subsequent visual inspection of the sulcus revealed 9 and a further exploration of the sulcus with curette revealed 13. Conclusion:For being relatively easy to ignore silicone rubber impression of gingival sulcus residual phenomenon after impression procedures, it should cause clinicians more attention to it. It would be prudent to consider a routine curettage of abutment sulci after impression-making.
