摘要
简介：本研究首次探讨了在三维打印义齿基托树脂中添加二氧化钛纳米管（TiO2）对义齿基托机械和物理性能的影响：试样由微软公司的 3D builder 软件通过计算机辅助设计进行数字化制作。根据横向强度、冲击强度、硬度、表面粗糙度和颜色稳定性等测试指标，设计并按照相关标准打印出一定尺寸的试样。在 3D 打印的义齿基底树脂（DentaBase，Asiga，澳大利亚）中添加 1.0% 和 1.5% 重量比的 TiO2 纳米管（直径：15-30 nm，长度：2-3 μm）。对弯曲强度、冲击强度（夏比冲击）、硬度、表面粗糙度和颜色稳定性进行了评估，并对收集的数据进行了方差分析和 Tukey 后检验（α = 0.05）。采用场发射扫描电子显微镜（FESEM）和能量色散 X 射线光谱（EDX）绘图来评估纳米管的分散情况：与对照组（0.0 wt.% TiO2 纳米管）相比，1.0 和 1.5 wt.% TiO2 纳米管增强组的平均弯曲度、冲击度和硬度值均显著增加。与纯树脂相比，两组纳米复合材料的颜色都发生了明显变化，与对照组相比，纳米复合材料的表面粗糙度大大降低：结论：在3D打印义齿基托材料中添加1.0和1.5 wt.%的TiO2纳米管可以提高材料的机械和物理性能，从而获得更好的临床表现：在临床应用方面，三维打印义齿基托材料已被证明可以替代传统的热固化材料。通过与纳米技术的结合，现有义齿可以得到显著提升，延长使用寿命，提高患者满意度，同时解决目前标准材料的缺陷。
The influence of the addition of titanium oxide nanotubes on the properties of 3D printed denture base materials
Introduction
In this study, the effects of adding titanium dioxide nanotubes (TiO2) to 3D-printed denture base resin on the mechanical and physical properties of denture bases were examined for the first time.
Methods
The specimens were digitally created using 3D builder software from Microsoft Corporation through computer-aided design. In accordance with the test specifications for transverse strength, impact strength, hardness, surface roughness, and color stability, specimens were designed and printed with certain dimensions following relevant standards. TiO2 nanotubes (diameter: 15–30 nm and length: 2–3 μm) were added to the 3D-printed denture base resin (DentaBase, Asiga, Australia) at 1.0% and 1.5% by weight. Flexural strength, impact strength (Charpy impact), hardness, surface roughness, and color stability were evaluated, and the collected data were analyzed with ANOVA followed by Tukey's post hoc test (α = 0.05). Field emission scanning electron microscopy (FESEM) and energy dispersive x-ray spectroscopy (EDX) mapping were used to evaluate the dispersion of the nanotubes.
Results
Compared with those of the control group (0.0 wt.% TiO2 nanotubes), the average flexural, impact, and hardness values of the 1.0 and 1.5 wt.% TiO2 nanotube reinforcement groups increased significantly. Both nanocomposite groups showed significant color changes compared to that of the pure resin, and there was a considerable reduction in the surface roughness of the nanocomposites compared to that of the control group.
Conclusion
Adding TiO2 nanotubes to 3D-printed denture base materials at 1.0 and 1.5 wt.% could enhance the mechanical and physical properties of the material, leading to better clinical performance.
Clinical Significance
In terms of clinical applications, 3D-printed denture base material has been shown to be a viable substitute for traditional heat-cured materials. By combining this with nanotechnology, existing dentures could be significantly enhanced, promoting extended service life and patient satisfaction while addressing the shortcomings of the current standard materials.
