The point for root canal filling which had a function of shape memory was produced by using Trans-1, 4-Polyisoprene experimentally. As the result of examination for the properties of workability and sealing, the space of root canal could be sealed by the recovery of shape for only one trial point for root canal filling easily and completely without the sealer and accessory point, and satisfactory sealing was gained for about two years. The temporary crown which could be cemented without temporary cement was also produced experimentally. The trial temporary crown almost not needed the adjustment for contact and occlusion.

采用Trans-1,4-Polyisoprene实验制作了具有形状记忆功能的根管充填点。作业性和密封性检查结果显示，根管充填试验点仅需1个试验点即可恢复形状，密封根管间隙，无需密封剂和辅助点，可轻松、完全密封，并获得满意的密封效果约两年。还试验制作了无需临时水泥即可粘合的临时冠。试验临时冠几乎不需要接触和咬合的调整。
