摘　　要：目的：研制一种单组份、糊剂型、水硬性暂封材料。方法：通过测定材料在水中的凝固速度及凝固后材料表面性状，对水硬性材料成份的种类、赋形剂的种类及凝固促进剂的种类进行筛选。结果：水硬性材料Ａ２的凝固速度最快，赋形剂Ｂ２的效果最好，凝固促进剂Ｃ１的作用优于Ｃ２。结论：采用Ａ２、Ｂ２、Ｃ１作为暂封材料基本组成效果最佳，凝固２４ｈ后抗压强度达１３．９４ＭＰａ±２．０７ＭＰａ。Aim:To develop a premixed temporary restorative material. Methods: According to their effects on the hardening depth and surface characteristic of the set materials, the water-hardening components, excipient vehicles, coagulation accelerators were selected. Results: Water-hardening material A 2 possessed the greatest hardenig depth within 24h. Excipient vechicle B 2 had the least effect on the hardening of the temporary restorative material. Accelerator C 1 was better than C 2 in coaguation accelertation. Conclusions: The compressive strength of the temporary restorative material which contained A 2B 2 C 1 as main components was 13.94±2.07MPa after hardening in 37℃water-bath.
