摘要: 氧化锆种植体因其优异的生物学及美学性能,在种植牙手术中应用愈发广泛。为进一步提升氧化锆种植体的骨结合率与种植成功率,提出了一种用于氧化锆模拟种植体复杂形状表面亲水改性的等离子体处理系统。该系统利用纳米银线制备作为同轴介质阻挡放电的外透明电极,将氧化锆种植体置于低压腔内轴电极上方,可在处理1 min后显著提升种植体表面亲水性。通过实验验证了系统可靠性与处理的有效性,并确定了系统最优处理参数,处理时间约60 s、绝对气压低于3 kPa、电源输出电压为7 kV时,氧化锆种植体亲水性最佳。

Abstract: Zirconia implants are increasingly being used in dental implant surgery owing to their excellent biological and aesthetic properties. To further improve the osseointegration and success rate of zirconia implants, a plasma treatment system for simulating hydrophilic modification of complex shaped zirconia implant surfaces was proposed. The system utilizes nano silver wires to prepare an external transparent electrode as the coaxial dielectric barrier for discharge. The zirconia implant is placed above the axis electrode in the low-voltage chamber, which can significantly improve the surface hydrophilicity of the implant after treatment within one minute. The reliability and effectiveness of the system were verified through experiments, and the optimal processing parameters were determined. When the implantation treatment time is about 60 s, the absolute air pressure is below 3 kPa, and the power output voltage is 7 kV, the zirconia implant shows the best hydrophilicity.

Key words: plasma, hydrophilic modification, implant, zirconia
