摘要： 目的:临床实验测试新型全口义齿印模边缘整塑材料的边缘封闭效果。方法:按相关专利配方,精细调整新型边缘整塑材料中石蜡、聚乙烯低聚物和增塑剂等各成分比例,使其软化点温度控制在37 ℃左右。临床选取23例无牙颌患者,分别采用边缘整塑印模膏和新型边缘整塑材料进行无牙颌个别托盘边缘肌能整塑后,测试与比较两种材料完成边缘封闭后的下颌个别托盘固位力。结果:应用两种材料进行边缘封闭后的下颌个别托盘固位力没有显著性差异(P＞0.05)。结论:新型边缘整塑材料临床操作便捷,肌能整塑的整体一致性更好,可以替代传统的边缘整塑印模膏实现良好的无牙颌个别托盘的边缘封闭效果。

Abstract: Objective: To test the border sealing efficiency of a new complete denture edge shaping impression material. Methods: By precisely controlling the proportion of paraffin, polyethylene oligomer and plasticizer according to the formula in relevant patent, the material softening temperature was maintained at about 37 ℃. Twenty-three edentulous patients were selected and each of them was respectively shaped with traditional modeling compound and the new edge shaping material during taking impression. Impression retention of the individual tray with edge shaping was recorded. Results: There was no significant difference in the retention of individual trays between the new edge shaping material and impression compound (P>0.05). Conclusion: The new edge shaping material has a convenient operation ability and satisfied consistency, which showed great border sealing, thus providing an alternative in edge shaping of complete denture.
