The success of dental implants depends on osseo-integration because titanium (Ti) maintains good mechanical stability while zirconia (Zr) prevents bacterial adhesion. The early-stage adhesion of MG-63 osteo-blast-like cells to Ti surfaces reached 78% ± 2.5% during the initial period (p<0.05). However, Zr demonstrated superior long-term cell proliferation and mineralization throughout the analysis period (p<0.05). The alkaline phosphatase (ALP) levels at day 7 remained comparable between Ti (1.25 ± 0.09 U/mL) and Zr (1.18 ± 0.07 U/mL) while Zr showed better growth of mineralized surface at day 14. Nonetheless, additional testing using animal subjects are required to confirm Zr as a suitable substitute for Ti implants.
种植牙的成功取决于骨结合，因为钛（Ti）能保持良好的机械稳定性，而氧化锆（Zr）可防止细菌黏附。在初始阶段，MG-63成骨样细胞与钛表面的早期黏附率在最初阶段达到78%±2.5%（p<0.05）。然而，在整个分析期内，氧化锆显示出卓越的长期细胞增殖和矿化能力（p<0.05）。第7天时，钛（1.25±0.09 U/mL）和氧化锆（1.18±0.07 U/mL）的碱性磷酸酶（ALP）水平相当，而在第14天时，氧化锆显示出更好的矿化表面生长情况。尽管如此，仍需要使用动物受试者进行额外测试，以确认氧化锆作为钛植入物的合适替代品。
