Wettability is recognized as an important property of implant surfaces for ensuring improved biological responses. However, limited information exists on how bone grafting procedures including materials influence the hydrophilic behavior of implant surfaces. This in vitro study aimed to investigate the influence of two bovine grafting materials after hydration on the wettability of four different disk surfaces: commercially pure titanium (CP-Ti), titanium-zirconium dioxide (TiZrO-Cerid), zirconia (SDS), and niobium. Wettability tests were performed on each of the four implant surfaces with a solution of 0.9% sodium chloride after mixture with W-bone (Group A) or Bio-Oss (Group B) or 0.9% sodium chloride alone (Group C). In total, 360 contact angle measurements were completed with = 30 per group. Statistical analysis was performed using a one-way analysis with variance (ANOVA) test with a significant mean difference at the 0.05 level. For pure titanium, Group A demonstrated increased hydrophilicity compared to Group B. Both TiZrO and zirconia showed significant differences for Groups A, B and C, exhibiting a decrease in hydrophilicity after the use of bovine grafting materials compared to titanium surfaces. Niobium remained consistently hydrophobic. In summary, this study revealed that bovine grafting materials may diminish the hydrophilicity of zirconia surfaces and exert varied effects on titanium and niobium. These findings contribute to the understanding of implant surface interactions with grafting materials, offering insights for optimizing biological responses in implantology.
润湿性被认为是植入物表面的一项重要特性，有助于改善生物学反应。然而，关于包括材料在内的骨移植程序如何影响植入物表面的亲水性，相关信息有限。这项体外研究旨在探究两种水合牛骨移植材料对四种不同圆盘表面润湿性的影响，这四种圆盘表面分别是商业纯钛（CP-Ti）、钛锆氧化物（TiZrO-Cerid）、氧化锆（SDS）和铌。在与W型骨（A组）或Bio-Oss（B组）混合后，或仅与0.9%氯化钠溶液（C组）混合后，对四种植入物表面分别进行润湿性测试。总共完成了360次接触角测量，每组30次。使用单因素方差分析（ANOVA）进行统计分析，显著平均差异水平为0.05。对于纯钛，A组相比B组亲水性增加。TiZrO和氧化锆在A、B、C组中均表现出显著差异，与钛表面相比，使用牛骨移植材料后亲水性降低。铌始终保持疏水性。总之，本研究表明牛骨移植材料可能会降低氧化锆表面的亲水性，并对钛和铌产生不同影响。这些发现有助于理解植入物表面与移植材料之间的相互作用，为优化植入学中的生物学反应提供了见解。
