With several denture adhesives available, it is important for dentists to make appropriate patient recommendations.
The purpose of this study was to evaluate the tensile bond strength of denture adhesives on denture base materials at time intervals of up to 24 hours.
Fixodent, Super Poligrip, Effergrip, and SeaBond denture adhesives were tested with 3 denture base materials: 2 heat-polymerized (Lucitone 199 and SR Ivocap) and 1 visible-light-polymerized (shade-stable Eclipse). Artificial saliva with mucin was used as a control. Tensile bond strength was tested in accordance with American Dental Association specifications at 5 minutes, 3 hours, 6 hours, 12 hours, and 24 hours after applying the adhesive. Maximum forces before failure were recorded in megapascals (MPa), and the data were subjected to a 2-way analysis of variance (α=.05).
All 4 adhesives had greater tensile bond strength than the control. Fixodent, Super Poligrip, and SeaBond had higher tensile bond strength values than Effergrip. All adhesives had the greatest tensile bond strength at 5 minutes and the least at 24 hours. The 3 denture bases produced significantly different results with each adhesive (P<.001). Lucitone 199 with the adhesives had the greatest tensile bond strength, followed by Ivocap and Eclipse.
All 4 adhesives had greater tensile bond strength than the control, and all 4 adhesives were strongest at the 5-minute interval. On all 3 types of denture bases, Effergrip produced significantly lower tensile bond strength, and Fixodent, Super Poligrip, and SeaBond produced significantly higher tensile bond strength. At 24 hours, the adhesive-base combinations with the highest tensile bond strength were Fixodent on Lucitone 199, Fixodent on Eclipse, Fixodent on Ivocap, and Super Poligrip on Ivocap.
有多种义齿粘合剂可供选择，因此牙医为患者做出恰当的推荐很重要。
本研究的目的是评估义齿粘合剂在长达24小时的时间间隔内对义齿基托材料的拉伸粘结强度。
使用Fixodent、Super Poligrip、Effergrip和SeaBond义齿粘合剂对3种义齿基托材料进行测试：2种热聚合材料（Lucitone 199和SR Ivocap）和1种可见光聚合材料（颜色稳定的Eclipse）。含有粘蛋白的人工唾液用作对照。根据美国牙科协会规范，在涂抹粘合剂后5分钟、3小时、6小时、12小时和24小时测试拉伸粘结强度。记录失效前的最大力，单位为兆帕（MPa），并对数据进行双向方差分析（α = 0.05）。
所有4种粘合剂的拉伸粘结强度均高于对照组。Fixodent、Super Poligrip和SeaBond的拉伸粘结强度值高于Effergrip。所有粘合剂在5分钟时的拉伸粘结强度最大，在24小时时最小。3种义齿基托与每种粘合剂产生的结果显著不同（P < 0.001）。使用粘合剂的Lucitone 199的拉伸粘结强度最大，其次是Ivocap和Eclipse。
所有4种粘合剂的拉伸粘结强度均高于对照组，且所有4种粘合剂在5分钟时最强。在所有3种义齿基托上，Effergrip的拉伸粘结强度显著较低，而Fixodent、Super Poligrip和SeaBond的拉伸粘结强度显著较高。在24小时时，拉伸粘结强度最高的粘合剂 - 基托组合为Lucitone 199上的Fixodent、Eclipse上的Fixodent、Ivocap上的Fixodent以及Ivocap上的Super Poligrip。
