Abstract

Objective: To investigate whether nonthermal atmospheric plasma (NTAP) can promote bonding between commonly used adhesive monomers and zirconia.

Materials and methods: The zirconia surface and monomers (HEMA, BisGMA, TEGDMA, and MDP) were treated with different NTAP approaches (10 w, 30 s), and the surface characteristics and chemical structures between the zirconia surface and monomers were verified by the contact angle, scanning electron microscopy (SEM), attenuated total reflectance Fourier transform infrared (ATR/FT-IR) spectroscopy, and x-ray photoelectron spectroscopy (XPS). Scotchbond Universal adhesive with two different resin cements, RelyX Ultimate and RelyX Unicem 2, was applied, followed by NTAP-aided clinical procedures, and then microtensile bond strength test (μTBS) and failure mode evaluation were tested for preliminary mechanical properties assessment. One-way ANOVA was employed for the statistical analysis.

Results: The contact angle analysis, SEM, and ATR-FTIR confirmed that NTAP can promote the polymerization of BisGMA, TEGDMA, and MDP on the zirconia surface, while XPS confirmed that NTAP can induce a chemical reaction between MDP and zirconia.

Conclusions: Nonthermal atmospheric plasma can increase the affinity between selected monomers and zirconia and promote the chemical bonding strength between phosphate monomers and zirconia; besides, it can enhance the bonding strength of two different adhesive systems.

Clinical significance: The mechanism of how NTAP improved common adhesive monomers interacting with zirconia surfaces was revealed in this study. NTAP, as a relatively high energy-boosting method, could not only improve the surface affinity of zirconia and chemical bonding in-between monomers and zirconia but also enhance the polymerization of different monomers onto zirconia, resulting in improved bonding properties. Thus, further exploration of versatile bonding materials and/or onto different dental substrates could take this into account.

非热大气等离子体可促进粘合剂单体与氧化锆之间的粘合。
目的:研究非热大气等离子体(NTAP)能否促进常用粘合单体与氧化锆之间的粘合:研究非热大气等离子体(NTAP)能否促进常用粘合剂单体与氧化锆之间的粘合:用不同的 NTAP 方法(10 w,30 s)处理氧化锆表面和单体(HEMA、BisGMA、TEGDMA 和 MDP),并通过接触角、扫描电子显微镜(SEM)、衰减全反射傅立叶变换红外光谱(ATR/FT-IR)和 X 射线光电子能谱(XPS)验证氧化锆表面和单体之间的表面特征和化学结构。使用带有两种不同树脂胶合剂(RelyX Ultimate 和 RelyX Unicem 2)的 Scotchbond 通用粘合剂,然后进行 NTAP 辅助临床程序,然后进行微拉伸粘接强度测试(μTBS)和失效模式评估,以初步评估机械性能。统计分析采用单因素方差分析:接触角分析、扫描电镜和 ATR-FTIR 证实,NTAP 可促进氧化锆表面的 BisGMA、TEGDMA 和 MDP 的聚合,而 XPS 证实,NTAP 可诱导 MDP 与氧化锆发生化学反应:结论:非热大气等离子体能增加选定单体与氧化锆之间的亲和力,促进磷酸单体与氧化锆之间的化学键合强度;此外,它还能增强两种不同粘合剂体系的粘合强度:本研究揭示了 NTAP 如何改善普通粘合剂单体与氧化锆表面相互作用的机理。NTAP作为一种相对较高的增能方法,不仅能改善氧化锆的表面亲和性以及单体与氧化锆之间的化学键,还能增强不同单体在氧化锆上的聚合,从而改善粘接性能。因此,在进一步探索多功能粘合材料和/或不同牙科基质时,应考虑到这一点。
