Abstract The present research aimed to evaluate the effect of sintering temperature (1300 °C, 1400 °C and 1600 °C) on short-term and long-term SBS values (SBS1 and SBS2, respectively) as well as grain size and surface roughness of a novel multi-layered monolithic zirconia material (Katana STML). One hundred and eighty-six samples (N = 186) of monolithic zirconia were prepared and randomly divided into three groups (n = 62) according to the final sintering temperatures. Two samples from each group were taken before and after sandblasting for scanning electron microscopy (SEM) examination. The surface roughness (Ra) values were determined. Sixty samples for each group were divided into three subgroups according to the resin cement (n = 20) and luting procedures were performed. Half of the specimens for each subgroup (n = 10) were non-aged, while the other half (n = 10) were aged before shear bond strength test (SBSt). One-way analysis of variance (ANOVA), two-way ANOVA and independent samples T-test were used to analyse the data. The sintering temperature, resin cement and their interaction were significant (p ≤ .05) for both aged and non-aged samples. The grain sizes and Ra values of monolithic zirconia significantly increased by the increase of sintering temperature (p ≤ .05). The aging significantly reduced SBS values (p ≤ .05). Sintering temperature and resin cement affected both SBS1 and SBS2 values between resin cement and monolithic zirconia (p ≤ .05). Application of 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) containing primer revealed an increase in long-term SBS values in response to the increase in sintering temperature.

不同的烧结条件是否会影响树脂粘固剂和目前使用的美学氧化锆之间的粘合强度？

摘要 本研究旨在评估烧结温度（1300 °C、1400 °C 和 1600 °C）对短期和长期 SBS 值（分别为 SBS1 和 SBS2）以及晶粒尺寸和表面粗糙度的影响。一种新型多层整体氧化锆材料（Katana STML）。制备了 186 个整体氧化锆样品 (N = 186)，并根据最终烧结温度随机分为三组 (n = 62)。喷砂前后每组取两个样品进行扫描电子显微镜（SEM）检查。确定表面粗糙度（Ra）值。每组 60 个样品根据树脂粘固剂（n = 20）分为三个亚组并进行粘合程序。每个亚组的一半样本 (n = 10) 未老化，而另一半 (n = 10) 在剪切粘合强度测试 (SBSt) 之前老化。使用单向方差分析（ANOVA）、双向方差分析和独立样本 T 检验来分析数据。老化和未老化样品的烧结温度、树脂水泥及其相互作用都很显着 (p ≤ .05)。随着烧结温度的升高，整体氧化锆的晶粒尺寸和 Ra 值显着增加（p ≤ .05）。老化显着降低了 SBS 值 (p ≤ .05)。烧结温度和树脂水泥影响树脂水泥和整体氧化锆之间的 SBS1 和 SBS2 值 (p ≤ .05)。应用含 10-甲基丙烯酰氧基癸基磷酸二氢酯 (10-MDP) 的底漆表明，随着烧结温度的升高，长期 SBS 值会增加。
