摘要 本研究的目的是验证釉料应用对Y-TZP 与饰面陶瓷之间剪切粘结强度的影响。准备了 30 个方形烧结氧化锆块（12.5 × 15 × 1.5 mm）（Vita In Ceram YZ for inLab，VITA Zahnfabrik），根据“釉料应用”因素（c – 对照/ g – 粉末和液体/ gs – 喷雾）随机分为三组（n = 10）。根据实验组的说法，在每个氧化锆表面上建造了一个 PM9（Vita）陶瓷圆柱体（∅：3mm；高度：3mm）。对样品进行热循环（12,000 次循环/5°C/55°C±2°C），并在万能试验机中进行剪切测试（1mm/min）。通过立体显微镜和扫描电镜对断裂样本进行分析。通过单向方差分析、Tukey 检验 (5%) 和 Weibull 分析对数据进行统计分析。方差分析显示，“釉料应用”因素 (p = 0.001) 非常显着。平均 (±SD) 剪切粘合数据 (MPa) 为 PM9c – 41.52 (±11.82)； PM9g – 24.14（±12.82）； PM9gs – 21.06 (±14.48)。釉料类型之间的粘结强度和威布尔模量没有显着差异（p > 0.05），但无论哪组，在使用釉料后特性强度（σ o）均显着下降。主要的失效类型是粘合性（76.66%），其次是混合性（23.34%）。可以得出的结论是，在本研究的限制范围内，Y-TZP 表面上的施釉，无论是粉末、液体还是喷雾，都没有提高压制贴面陶瓷的粘结强度。
Abstract The objective of this study was to verify the influence of glaze application on the shear bond strength between Y-TZP and veneering ceramic. Thirty square-shaped blocks (12.5 × 15 × 1.5 mm) of sintered zirconia (Vita In Ceram YZ for inLab, VITA Zahnfabrik) were prepared, randomly divided into three groups (n = 10), according to the factor ‘glaze application’ (c – control/ g – powder and liquid/ gs – spray). On each zirconia surface, a cylinder of PM9 (Vita) ceramic was built (∅: 3 mm; height: 3 mm), according to the experimental group. Specimens were thermocycled (12,000 cycles/5 °C/55 °C ± 2 °C) and submitted to shear testing in a universal testing machine (1 mm/min). Analysis of fractured specimens ware performed through stereomicroscopy and SEM. Data were statistically analyzed through one-way ANOVA, Tukey’s test (5%) and Weibull's analysis. ANOVA revealed that the factor ‘glaze application’ (p = 0.001) was significant. The mean (±SD) shear bond data (MPa) were PM9c – 41.52 (±11.82); PM9g – 24.14 (±12.82); PM9gs – 21.06 (±14.48). There were no significant differences among glazed types for bond strength and Weibull modulus (p > 0.05), however the Characteristic strength (σ o) decreased significantly after the application of the glaze, regardless of the group. The predominant type of failure was adhesive (76.66%) followed by mixed (23.34%). It can be concluded that, within the limitations of this study, the glazing application on Y-TZP surface, either powder and liquid or spray, did not improve the bond strength to pressed veneering ceramic.
