Abstract

Purpose: This study investigated the effect of different surface treatments and the effect of silane heat treatment with laser on the shear bond strength (SBS) of a nanoceramic composite to repaired hybrid CAD/CAM blocks.

Materials and methods: 60 hybrid CAD/CAM specimens (Cerasmart, GC) were prepared and randomly divided into six groups according to the different surface treatments (n = 10): group ER: Er:YAG laser+silane (Monobond Plus, Ivoclar Vivadent); group ER+SHT: Er:YAG laser+silane heat treatment; group B: bur+silane; group B+SHT: bur+silane heat treatment; group HF: hydrofluoric acid+silane; group HF+SHT: hydrofluoric acid+silane heat treatment. Afterwards, a universal adhesive (Universal Bond Quick, Kuraray) was applied, and nanoceramic resin composite (Zenit, President) cylinders were bonded to the Cerasmart specimens. They were thermocycled for 10,000 cycles (5-55°C) and subjected to SBS testing using a universal testing machine. Failure modes were examined with a stereomicroscope (15X). Scanning electron microscopy (SEM) was used to evaluate the surface topography (n = 2). The data were statistically analyzed using the Mann-Whitney U-test and the Kruskal-Wallis test (p < 0.05).

Results: Regarding the surface treatments, group ER showed significantly lower SBS than groups B and HF (p < 0.05). Regarding the presence of silane heat treatment by laser, groups ER+SHT and B+SHT showed significantly lower SBS than group HF+SHT(p < 0.05). In addition, group B+SHT showed significantly lower SBS than did group B (p < 0.05).

Conclusion: Er:YAG laser treatment for repairing hybrid CAD/CAM blocks was not as effective as bur roughening or hydrofluoric acid etching. Silane heated by Er:YAG laser was incapable of significantly increasing the bond strength to repaired hybrid CAD/CAM blocks.

用激光对硅烷进行热处理后，混合 CAD/CAM 材料的修复粘接强度。

目的：本研究探讨了不同表面处理方法和激光硅烷热处理对纳米陶瓷复合材料与修复的混合 CAD/CAM 块体的剪切结合强度（SBS）的影响。Er：YAG 激光+硅烷热处理；B 组：毛刺+硅烷；B+SHT 组：毛刺+硅烷热处理；HF 组：氢氟酸+硅烷；HF+SHT 组：氢氟酸+硅烷热处理。然后，涂上通用粘合剂（Universal Bond Quick，可乐丽），并将纳米陶瓷树脂复合材料（Zenit，总统）圆柱体粘合到 Cerasmart 试样上。这些试样经过 10,000 次热循环（5-55°C），并使用万能试验机进行 SBS 试验。使用体视显微镜（15 倍）检查失效模式。扫描电子显微镜（SEM）用于评估表面形貌（n = 2）。采用 Mann-Whitney U 检验和 Kruskal-Wallis 检验对数据进行统计分析（P < 0.05）：结果：在表面处理方面，ER 组的 SBS 明显低于 B 组和 HF 组（p < 0.05）。在使用激光进行硅烷热处理的情况下，ER 组+SHT 和 B 组+SHT 的 SBS 明显低于 HF 组+SHT（p < 0.05）。此外，B+SHT 组的 SBS 明显低于 B 组（P < 0.05）：结论：Er:YAG 激光治疗修复混合 CAD/CAM 块的效果不如毛刺粗化或氢氟酸蚀刻。用 Er:YAG 激光加热硅烷无法显著提高修复后的混合 CAD/CAM 块的粘接强度。

期刊介绍： New materials and applications for adhesion are profoundly changing the way dentistry is delivered. Bonding techniques, which have long been restricted to the tooth hard tissues, enamel, and dentin, have obvious applications in operative and preventive dentistry, as well as in esthetic and pediatric dentistry, prosthodontics, and orthodontics. The current development of adhesive techniques for soft tissues and slow-releasing agents will expand applications to include periodontics and oral surgery. Scientifically sound, peer-reviewed articles explore the latest innovations in these emerging fields.
