Conventionally veneered zirconia restorations are susceptible to chipping and spalling of the veneering material. The novel translucent zirconias were developed to overcome such issues, although layered zirconia restorations can be re-designed to improve mechanical performance. Thus, the aim of this study was to analyze the strength and structural reliability of zirconia bilayers using conventional (porcelain ceramic under tensile stress) and bioinspired (zirconia under tensile stress) configurations. Sol-gel silica infiltration served as a smooth transition between the zirconia and veneering porcelain. Failure mode and interfacial adhesive mechanism were analyzed using scratch test and interfacial indentation. Bilayered specimens were produced for biaxial flexural testing with Y-TZP and pressed ceramic, which were further divided into four groups (n = 30): Conventional (C), Infiltrated conventional (IC), Bioinspired (B) and Infiltrated bioinspired (IB). The results of biaxial flexural strength tests were analyzed by Weibull analysis (95% CI) for determination of the Weibull modulus (m). The infiltration layer was characterized by XRD and SEM, FEG-SEM and EDS. The bioinspired infiltrated group was the most reliable (m = 9.59), although the fine damage of veneered conventional (conventional) zirconia demonstrated its superior resistance to scratching and debonding. Therefore, the filling of superficial defects by zirconia silicate demonstrated the need for mechanical retention for better porcelain adhesion.

常规地，单板氧化锆修复体容易受到饰面材料的碎裂和剥落的影响。尽管可以重新设计分层的氧化锆修复体以改善机械性能，但仍开发了新型的半透明氧化锆以克服此类问题。因此，本研究的目的是分析使用常规（拉伸应力下的陶瓷陶瓷）和生物启发（拉伸应力下的氧化锆）构型的氧化锆双层的强度和结构可靠性。溶胶-凝胶二氧化硅渗透是氧化锆和贴面瓷之间的平滑过渡。使用划痕试验和界面压痕分析了失效模式和界面粘合机理。使用Y-TZP和压制陶瓷制作了双层试样，用于双轴弯曲测试，分为四类（n = 30）：常规（C），常规常规（IC），仿生（B）和常规仿生（IB）。通过Weibull分析（95％CI）分析双轴弯曲强度测试的结果，以确定Weibull模量（m）。通过XRD和SEM，FEG-SEM和EDS对渗透层进行表征。尽管单板常规（常规）氧化锆的细微损伤表现出对刮擦和脱胶的超强抵抗力，但生物启发性渗透组是最可靠的（m = 9.59）。因此，用硅酸锆填充表面缺陷表明需要机械固位以提高瓷器的附着力。通过Weibull分析（95％CI）分析双轴弯曲强度测试的结果，以确定Weibull模量（m）。通过XRD和SEM，FEG-SEM和EDS对渗透层进行表征。尽管单板常规（常规）氧化锆的细微损伤表现出对刮擦和脱胶的超强抵抗力，但生物启发性渗透组是最可靠的（m = 9.59）。因此，用硅酸锆填充表面缺陷表明需要机械固位以提高瓷器的附着力。通过Weibull分析（95％CI）分析双轴弯曲强度测试的结果，以确定Weibull模量（m）。通过XRD和SEM，FEG-SEM和EDS对渗透层进行表征。尽管单板常规（常规）氧化锆的细微损伤表现出对刮擦和脱胶的超强抵抗力，但生物启发性渗透组是最可靠的（m = 9.59）。因此，用硅酸锆填充表面缺陷表明需要机械固位以提高瓷器的附着力。单板常规（常规）氧化锆的细微损伤显示出其优异的耐刮擦和抗粘连性。因此，用硅酸锆填充表面缺陷表明需要机械固位以提高瓷器的附着力。单板常规（常规）氧化锆的细微损伤显示出其优异的耐刮擦和抗粘连性。因此，用硅酸锆填充表面缺陷表明需要机械固位以提高瓷器的附着力。
