纳米非晶金刚石薄膜对树脂人工牙耐磨性及其影响因素的实验研究

目的：研究不同镀膜方法对纳米非晶金刚石薄膜提高树脂人工牙耐磨性能的影响。方法：分别用极化和紫外光照射的方法对人工牙进行预处理后，在其表面分别镀制50nm和100nm的纳米非晶金刚石薄膜，通过对其耐磨性能的测试，评价不同预处理方法和不同厚度薄膜对提高人工牙表面耐磨性能的影响。结果：纳米非晶金刚石薄膜能显著提高树脂人工牙耐磨性能；两种预处理方法中，极化法实验组的耐磨性能明显优于紫外光照法实验组；极化处理后镀膜50nm的人工牙的耐磨性能最接近于天然牙釉质。结论：纳米非晶金刚石薄膜能够提高树脂人工牙的耐磨性能，处理的方法应选择极化法，薄膜的厚度控制在50nm为最佳。

A study of the influencing factors of nanometer amorphous diamond film on the wearing resistance of resinic artificial teeth

Objective To observe the effect of nanometer amorphous diamond film on the wearing resistance of resinic artificial teeth. Methods The resinic artificial teeth were deposited with 50nm or 100nm nanometer amorphous diamond film after pretreated with ultraviolet radiation or polarization.The effect of different methods of pretreatment and thickness of nanometer amorphous diamond films on the wearing resistance of resinic artificial teeth was evaluated. Results Resinic artificial teeth deposited with 50nm amorphous diamond film after pretreated with polarization are most close to the natural enamel. Conclusion Nanometer amorphous diamond film improves significantly the wearing resistance of resinic artificial teeth.Resinic artificial teeth should be deposited with 50nm nanometer amorphous diamond film after pretreated with polarization.
