The prevention of aseptic loosening and peri-implantitis is crucial for the success of dental implant surgery. In this study, different doses of Ag-implanted TiN/Ag nanomultilayers were prepared on the sandblasting with large grit and acid etching (SLA)-Ti surface using a multiarc ion-plating system and an ion-implantation system, respectively. The physical and chemical properties of the samples were assessed using various techniques, including scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, atomic force microscopy, inductively coupled plasma atomic emission spectrometry, and water contact angle measurements. In addition, the applicability and biosafety of the SLA/1 × 10-Ag and SLA/1 × 10-Ag surfaces were determined via biocompatibility testing in vivo and in vitro. The results demonstrated that the physical and chemical properties of SLA/1 × 10-Ag and SLA/1 × 10-Ag surfaces were different to some extent. However, compared with SLA-Ti, silver-loaded TiN/Ag-modified SLA-Ti surfaces (SLA/1 × 10-Ag) with enhanced bacteriostatis, osteogenesis, and biocompatibility have great potential for dental applications.
预防无菌性松动和种植体周围炎对于牙种植手术的成功至关重要。在本研究中，分别使用多弧离子镀系统和离子注入系统，在大颗粒喷砂和酸蚀（SLA）钛表面制备了不同剂量银植入的TiN/Ag纳米多层膜。使用多种技术评估样品的物理和化学性质，包括扫描电子显微镜、能量色散光谱、X射线衍射、X射线光电子能谱、原子力显微镜、电感耦合等离子体原子发射光谱法和水接触角测量。此外，通过体内和体外生物相容性测试确定SLA/1×10⁻⁶Ag和SLA/1×10⁻⁸Ag表面的适用性和生物安全性。结果表明，SLA/1×10⁻⁶Ag和SLA/1×10⁻⁸Ag表面的物理和化学性质在一定程度上有所不同。然而，与SLA钛相比，负载银的TiN/Ag修饰的SLA钛表面（SLA/1×10⁻⁶Ag）具有增强的抑菌、成骨和生物相容性，在牙科应用中具有巨大潜力。
