Abstract

This study investigated the influence of different surface treatments on unfiring or firing zirconia-reinforced lithium silicate (ZLS) glass-ceramics. Celtra Duo and IPS e.max CAD blocks were cut and process following manufacturer protocols. The specimen surface was treated with seven different protocols. Two ceramic blocks with the same surface treatment were bonded with luting agent and prepared for mini-interfacial fracture toughness tests (mini-iFT). The specimens were tested after 1-week storage. The data was statistically analyzed using two-way ANOVA and Dunnett's T3 comparison (α=0.05). The highest mini-iFT of both Celtra Duo unfired and fired was shown in the HF+S group, which was not significantly different from HF+S+UA. For IPS e.max CAD, the mini-iFT was higher in the groups treated with hydrofluoric acid. Additional adhesive after silane application did not significantly improve bonding effectiveness. Therefore, surface treatment with hydrofluoric acid and silane is recommended for both unfiring and firing ZLS glass ceramics.

氧化锆增强硅酸锂玻璃陶瓷不同表面处理的界面断裂韧性。

研究了不同表面处理对未烧制或烧制氧化锆增强硅酸锂（ZLS）微晶玻璃的影响。按照制造商协议切割和加工Celtra Duo和IPS e.max CAD块。用七种不同的方案对样品表面进行处理。两个具有相同表面处理的陶瓷块用粘合剂粘合，并制备用于微型界面断裂韧性测试（mini-iFT）。样品在储存1周后进行测试。使用双向ANOVA和Dunnett T3比较（α=0.05）对数据进行统计分析。未烧制和烧制的Celtra Duo的最高迷你iFT显示在HF+s组，与HF+s+UA没有显著差异。对于IPS e.max CAD，氢氟酸处理组的最小iFT较高。在施用硅烷后添加粘合剂并没有显著提高粘合效果。因此，无论是未烧制还是烧制ZLS微晶玻璃，都建议使用氢氟酸和硅烷进行表面处理。

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%.
