Abstract

This study aimed to assess the effect of various surface roughening techniques on the shear bond strength of three new-generation zirconia ceramics. Specimens of 4Y-TZP/5Y-TZP zirconia (IPS e.max ZirCAD), 3Y-TZP monolithic zirconia (Vita YZ HT), and 3Y-TZP/5Y-TZP zirconia (IPS e.max ZirCAD Prime) were prepared using CAD/CAM and sintered as per manufacturers' instructions. Four surface treatments—control, sandblasting, tribochemical silica coating(TSC), and Er:YAG laser etching—were applied to yield 12 subgroups (n = 10). Specimens were treated with an MDP primer and cemented using dual-cure self-adhesive resin cement. Shear bond strength was measured using a universal testing machine at 1 mm/min. Statistical analysis included Shapiro-Wilk, two-way analysis of variance (ANOVA), and Tukey HSD tests (p < 0.05). Sandblasting and TSC significantly improved shear bond strength (p < .001). The Vita YZ HT group exhibited higher bond strength compared with IPS e.max ZirCAD (p = 0.004). Cohesive and mixed fractures predominated in sandblasting and TSC groups, whereas Er:YAG laser treatment yielded bond strength similar to controls (p = .386). Shear bond strength is influenced by the type of zirconia ceramic, surface treatment, and their interaction (p < .001). Sandblasting and TSC are highly effective, underscoring the clinical importance of surface preparation for durable zirconia bonding.

不同表面处理对新一代氧化锆剪切结合强度的影响

本研究旨在评估不同表面粗化工艺对三种新一代氧化锆陶瓷剪切结合强度的影响。采用CAD/CAM软件制备4Y-TZP/5Y-TZP氧化锆（IPS e.max ZirCAD）、3Y-TZP单片氧化锆（Vita YZ HT）和3Y-TZP/5Y-TZP氧化锆（IPS e.max ZirCAD Prime）试样，并按照生产厂家说明进行烧结。采用四种表面处理-控制、喷砂、摩擦化学二氧化硅涂层（TSC）和Er:YAG激光蚀刻-产生12个亚组（n = 10）。样品用MDP底漆处理，用双固化自粘树脂水泥胶结。剪切粘接强度采用万能试验机，以1 mm/min的速度测量。统计分析包括Shapiro-Wilk、双向方差分析（ANOVA）和Tukey HSD检验(p <；0.05)。喷砂和TSC显著提高了剪切强度(p <；措施)。与IPS e.max ZirCAD相比，Vita YZ HT组具有更高的粘结强度（p = 0.004）。喷砂组和TSC组以内聚性和混合性骨折为主，而Er:YAG激光治疗的结合强度与对照组相似（p = .386）。剪切键合强度受氧化锆陶瓷类型、表面处理及其相互作用的影响(p <；措施)。喷砂和TSC是非常有效的，强调表面处理的临床重要性持久的氧化锆键合。
