摘　　要：对接枝硅豫胶弹性印模材料的组成和性能进行了研究,经物理机械性能测试,线收缩为0.39％,凝固时间在4～6分钟。弹性好,不易撕裂,体积稳定。经生物学测试无毒性和刺激性;经临床应用,所取印模表面光滑,清晰,灌注成石膏模型表面光洁,所作修复体部获得良好效果。该弹性材料适用于口腔科制作修复体的印模和教育印模之用。The article presents a study on composition and property of a new impressionable material of Grafted silicome, The results showed its Shrinkage was 0.39%, and Soliditying time was from 4 to 6 minutes. Adequate tear resistance, good elasticity property, and dimansional stability were also verified. Biological property test revealed the materials were neither toxicity nor irritation. Through clinical application thay were able to reproduce fine dental plaster stone form Grafted silicone impression A good fit of restoration could be fabricated. These Properties were suitable for dental impressions and educational impressions.
