Abstract

This study evaluated the influence of applied pressure on the shear bond strength (SBS) between commercial 3Y-TZP zirconia and self-adhesive resin cement. Five test groups were created, each subjected to different applied pressures: 195.15, 97.47, 48.74, 9.75, and 0.20 kPa. A piston-type shear device was used to assess the effect of these pressures on cement layer thickness and SBS. The results demonstrated that the highest applied pressure (195.15 kPa) produced the thinnest cement layers (36.60 ± 1.67 μm) and the highest SBS values (58.8 ± 1.6 MPa), whereas the lower applied pressure (0.20 kPa) resulted in the thickest cement layers (73.20 ± 1.64 μm) and significantly lower SBS (30.8 ± 2.0 MPa). Regression analysis confirmed a strong correlation (R² = 0.82, p < 0.05) between cement thickness and SBS, indicating that cement thickness is a critical factor influencing adhesion. These findings highlight the importance of controlling applied pressure during cementation to optimize bonding performance. Standardizing pressure application through calibrated pressure devices may improve the durability of zirconia-based restorations and minimize variability during the cementation process.

施加压力和厚度变化对3Y-TZP氧化锆与自粘树脂水泥粘结强度的影响

本研究评估了施加压力对3Y-TZP商用氧化锆与自粘树脂水泥之间剪切粘结强度（SBS）的影响。创建了五个测试组，每个组承受不同的施加压力：195.15、97.47、48.74、9.75和0.20 kPa。采用活塞式剪切装置评估了这些压力对水泥层厚度和SBS的影响。结果表明：在最高施加压力（195.15 kPa）下，水泥层最薄（36.60±1.67 μm）， SBS值最高（58.8±1.6 MPa）；在较低施加压力（0.20 kPa）下，水泥层最厚（73.20±1.64 μm）， SBS值显著降低（30.8±2.0 MPa）。回归分析证实水泥厚度与SBS之间存在较强的相关性（R2 = 0.82, p < 0.05），说明水泥厚度是影响粘附的关键因素。这些发现强调了在胶结过程中控制施加压力以优化胶结性能的重要性。通过校准压力装置标准化压力应用可以提高氧化锆基修复体的耐久性，并最大限度地减少胶结过程中的变化。

期刊介绍： Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats: • original research reports • short research and development reports • scientific reviews • current concepts articles • special reports • editorials Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
