Abstract
This study aimed to evaluate the effects of dentin bonding agents and silanization on the bond strength between 3D printed resin and composite resin and compare it with a conventional composite resin. 3D printed resin cylinders (PCB) and composite resin substrates (Z250) were prepared and divided into eight subgroups based on the bonding agents used (n=12). The shear bond strength was measured using a universal testing machine, and the failure modes were evaluated. The bond strength was found to vary significantly among the bonding agents and substrate types. Silane application did not significantly improve the bond strength. Among the bonding agents, the universal adhesives exhibited the highest bond strengths for both substrates. Compared to PCB, Z250 demonstrated stronger bonds and exhibited more cohesive failures. Further research is needed to optimize the surface treatments and resin formulations for enhanced bond strength and durability between 3D printed and composite resins.
本研究旨在评估牙本质粘接剂和硅烷化对 3D 打印树脂和复合树脂之间粘接强度的影响，并将其与传统复合树脂进行比较。研究人员制备了三维打印树脂圆柱体（PCB）和复合树脂基底（Z250），并根据所使用的粘接剂将其分为八个亚组（n=12）。使用万能试验机测量了剪切粘接强度，并对失效模式进行了评估。结果发现，不同粘接剂和基底类型的粘接强度差异很大。使用硅烷并不能明显提高粘接强度。在粘合剂中，通用粘合剂对两种基材的粘合强度最高。与 PCB 相比，Z250 表现出更强的粘接强度，并出现更多内聚失效。需要进一步研究优化表面处理和树脂配方，以提高 3D 打印与复合树脂之间的粘接强度和耐用性。
期刊介绍：
Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
