BACKGROUND
Titanium has always been the material of choice for dental implants. The present study was conducted to assess effect of fluoride on titanium dental implants.
MATERIALS AND METHODS
Forty samples of pure titanium and Ti-6Al-4V were tested in an electrochemical cell.
RESULTS
Ecorr/V of titanium implant in artificial saliva was -0.42, and in artificial saliva, +0.25% NaF was -0.63. Ecorr/V of Ti-6Al-4V in artificial saliva was -0.56 and in artificial saliva +0.25% NaF was -0.60.
CONCLUSION
There was significant effect of fluoride on titanium implants in terms of corrosion.
背景
钛一直是牙种植体的首选材料。本研究旨在评估氟对钛牙种植体的影响。
材料与方法
在一个电化学池中对40个纯钛和Ti-6Al-4V样本进行了测试。
结果
钛种植体在人工唾液中的自腐蚀电位（Ecorr/V）为-0.42，在含0.25% NaF的人工唾液中为-0.63。Ti-6Al-4V在人工唾液中的自腐蚀电位为-0.56，在含0.25% NaF的人工唾液中为-0.60。
结论
就腐蚀而言，氟对钛种植体有显著影响。
