影响牙科用钛和钛合金种植体腐蚀性的因素

The influential factors on the corrosion properties of titanium and titanium alloys

钛和钛合金广泛应用于种植体,但口腔是一个复杂的理化环境,食物、牙膏制剂、漱口水及不同金属修复体的存在等因素可左右钛和钛合金表面氧化膜的稳定性,影响其耐腐蚀性能,进而影响牙科种植体的生物相容性及其功能和使用寿命,甚至导致种植体的失败。本文就影响钛和钛合金种植体腐蚀性的因素作一综述。

Titanium and titanium alloys are widely used as dental implant materials. But the environment of mouth is complicated. The influential factors such as food, toothpaste, gargarisma and different metal prosthesis will affect the oxide film of the surface of titanium and titanium alloys and affect the corrosion properties of the titanium and titanium alloys. Then they will affect the biocompatibility and function and lifetime of the dental implant, even lead to the failure of the implant. The article focused on the influential factors on the corrosion properties of titanium and titanium alloys.
