目标.评价最近和以前引入的软衬材料与不同聚合技术和不同含水量的义齿基托聚合物的初始粘结性能。采用改良的方法评估了10种软衬（Mollosil Plus、Dentusil、Ufi gel Soft、GC Reline Soft、Silagum Comfort、Vertex Soft、Astron Soft、Molloplast B、Flexacryl Soft、Triad Resline）与3种义齿基托聚合物（Paladon 65、Palapress Vario、Ivocap Plus）的初始拉伸粘结强度。Paladon 65试件在水中浸泡3个月后，测试义齿基托聚合物含水量对粘结强度结果的影响。测试后，对断裂表面进行目视检查并对界面结构进行SEM研究。还测试了每种软内衬材料的拉伸强度。所得数据采用双因素方差分析（α = 0.05）进行统计学处理。两组间抗张粘结强度差异有统计学意义（P < 0.05）。乙烯基聚（有机硅氧烷）软衬（Mollosil Plus、Dentusil、Ufi gel Soft、GC Reline Soft、Silagum Comfort）和增塑PMMA软衬（Vertex Soft）对不同义齿基托聚合物的粘结强度结果具有统计学相似性（P > 0.05）。对于其他材料（Astron Soft，Molloplast B，Flexacryl Soft，Triad Resline），不同的义齿基托聚合物导致显著不同的结果（P < 0.05）。聚（有机硅氧烷）基材料与水浸试样的粘结强度结果略高于干试样。显著性。与Molloplast B相比，本研究中使用的各种新配制的软内衬的粘合强度结果相当或更好。(C)2006年，牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
Objectives. To evaluate the initial bonding properties of recently and previously introduced soft relining materials to denture base polymers with different polymerization techniques and different water content.Methods. The initial tensile bond strength of 10 soft liners (Mollosil Plus, Dentusil, Ufi gel Soft, GC Reline Soft, Silagum Comfort, Vertex Soft, Astron Soft, Molloplast B, Flexacryl Soft, Triad Resiline) to three denture base polymers (Paladon 65, Palapress Vario, Ivocap Plus) were assessed with a modified method. Paladon 65 specimens immersed in water for 3 months were also used to test the effect of water content of denture base polymer on bond strength results. After testing, a visual examination of the fracture surfaces and a SEM investigation of the interface structure were performed. Tensile strength of each soft liner material was also tested. Data were analyzed statistically by two-way ANOVA (alpha= 0.05).Results. Significant differences were found among tensile bond strength results (P < 0.05). Vinyl poly(organosiloxane) soft liners (Mollosil Plus, Dentusil, Ufi gel Soft, GC Reline Soft, Silagum Comfort) and a plasticized PMMA soft liner (Vertex Soft) gave statistically similar bond strength results for different denture base polymers (P > 0.05). For the other materials used (Astron Soft, Molloplast B, Flexacryl Soft, Triad Resiline), different denture base polymers caused significantly different results (P < 0.05). Poly(organosiloxane) based materials gave slightly higher bond strength results with water immersed specimens than with the dry specimens.Significance. A wide variety of newly formulated soft liners used in this study gave comparable or better bond strength results compared to Molloplast B. (C) 2006 Academy of Dental Materials.
