The objective of this study was to evaluate and compare microleakage and bond strength values resulting from various surface treatments and adhesive system processes applied to different resin materials.
270 samples of two different 3D resin materials (Saremco Crowntec-Saremco Denture) were prepared by various surface treatments (control: Group C, hydrofluoric acid application: Group A, tribochemical sandblasting: Group T), adhesive systems (bond: Group B, resin cement: Group R, resin: Group P) (n = 30). Microleakage and bond strength tests were performed, and the data obtained were analyzed by a two-way ANOVA.
The findings revealed statistically significant differences among the analyzed groups (p < 0.001). While the mean values of microleakage in Group C were the highest (0.15 ± 0.04 mm), no significant difference was found between Group A (0.13 ± 0.05 mm) and Group T (0.14 ± 0.03 mm). When the bond strength was compared, Group B showed the highest bond strength value (8.50 ± 1.79 MPa) while Group P showed the lowest bond strength value (3.08 ± 1.61 MPa).
The study found that applying Group A (2.50 ± 1.47 MPa) weakened the bond, while Group T (3.78 ± 2.63 MPa) had lower values than Group C (13.52 ± 1.37 MPa). Among the adhesive systems, bond application showed the best performance. The application of surface treatment decreases bond strength with reduced microleakage. These findings emphasize the importance of selecting appropriate adhesive systems for 3D-printed complete dentures in clinical applications. It shows the best ways for both clinicans and patients to bond in order to meet the mechanical and aesthetic needs that come up with long-term prostheses use.
本研究的目的是评估和比较应用于不同树脂材料的各种表面处理和粘接系统工艺所产生的微渗漏和粘接强度值。
通过各种表面处理（对照：C组，氢氟酸处理：A组，摩擦化学喷砂：T组）、粘接系统（粘接剂：B组，树脂水门汀：R组，树脂：P组）制备了两种不同的三维树脂材料（Saremco Crowntec-Saremco义齿）的270个样本（n = 30）。进行了微渗漏和粘接强度测试，并对获得的数据进行双向方差分析。
研究结果显示分析组之间存在统计学显著差异（p < 0.001）。C组的微渗漏平均值最高（0.15±0.04mm），而A组（0.13±0.05mm）和T组（0.14±0.03mm）之间未发现显著差异。比较粘接强度时，B组显示出最高的粘接强度值（8.50±1.79MPa），而P组显示出最低的粘接强度值（3.08±1.61MPa）。
研究发现应用A组（2.50±1.47MPa）会削弱粘接，而T组（3.78±2.63MPa）的值低于C组（13.52±1.37MPa）。在粘接系统中，粘接剂的应用表现最佳。表面处理的应用会降低粘接强度并减少微渗漏。这些发现强调了在临床应用中为3D打印全口义齿选择合适的粘接系统的重要性。它展示了临床医生和患者为满足长期使用假体时出现的机械和美学需求而进行粘接的最佳方法。
