本研究调查了义齿清洁剂对丙烯酸和硅胶基软义齿衬里拉伸粘结强度的影响。所研究的义齿衬里是以丙烯为基础的热固化(Vertex Soft)，以丙烯酸为基础的自动固化(CoE Soft)，以硅基为基础的热固化(Molloplast-B)和以硅基为基础的自动固化(Mollosil Plus)。软衬试件尺寸为10×10×3 mm，按制造商说明在2个聚甲基丙烯酸甲酯(PMMA)块之间加工进行测试。将试件在37̊C的水和Polident中分别保存1天、1周、1、3和6个月，以20 mm/min的十字头速度测量拉伸粘结强度(每个实验组10个试件)。数据分析采用方差分析和图基HSD方法(α=0.05)。结果表明，所有衬里材料的拉伸粘结强度均随储藏时间的延长而降低，不同处理间无差异。
This study investigated the effect of a denture cleanser on tensile bond strength of acrylic and silicone-based soft denture liners. The denture liners investigated were an acrylicbased, heat-cured (Vertex soft), an acrylic-based, auto-cured (Coe soft), a silicon-based, heat-cured (Molloplast-B) and a silicon-based, auto-cured (Mollosil plus). Soft liner specimens were 10×10×3 mm in size and processed for testing according to manufacturers’ instructions between 2 polymethyl methacrylate (PMMA) blocks. Specimens were stored for 1 day, 1 week and 1, 3 and 6 months in water and Polident at 37 ̊C. Tensile bond strength was measured using a universal testing machine (Testometric Micro 500) at a crosshead speed of 20 mm/min (n=10 specimens per experimental group). ANOVA and Tukey HSD methods were used to analyze the data (α=.05). The results indicated that the tensile bond strength of all lining materials decreased with storage duration (both water and Polident), and no difference between treatments.
