Effect of electric charge on titanium Implant.

目前，替尼姆是最常用的牙种植体。种植体基牙通常采用金属冠处理，使用牙科合金。在牙科治疗中，钛的电离倾向比其他任何合金都大。如果钛基牙与另一种牙科合金发生电性接触，预计会有一种电子货币通过金属和(骨)组织。我们有几种牙科金属，它们是牙科用合金、医用不锈钢合金和18K金合金。将纯钛和牙科合金分别放置在容器中，并注入人血清。使用电桥电路测量钛和另一种牙科合金之间的电压。钛合金与牙科合金之间的电压最大。他们之间的货币依赖于金属表面的平方，货币在几分钟后逐渐下降。可以解释的是，金属表面发生了极化，金属表面也发生了钝化。我们在钛平板上培养了一株细胞系(NA细胞)，在塑料盘中培养了另一种牙科合金。这两种金属在同一盘中是电接触的，在控制盘中是不接触的。在电接触盘中，细胞在金属表面的附着被抑制。

Recently, titanimu is most commonly used in dental implants. The implant abutment is usually treated by metal crown, using dental alloy. The ionizing tendency of titanium is greater than any other alloys using in dental treatment. If the titanium abutment is electorically contated with another dental alloy, it is expected that an electric currency is pass through the both metals and also (bone) tissue.We sellect several dental metals, they are dental paradium allyo, stainless allyo for medical use and 18K gold allyo. Pure titanium and dental allyo were standed in the container and filled with human serum. The voltage was measured between titanium and another dental allyo, using a bridge circuit. The voltage between titanium and dental paradium allyo was the greatest between these three allyos. The currency between them is dependent on the square of metal surface, and the currency was gradualy decreased after few minutes. It can be explained the polarization was occurred on the metal surfaces and also the surface of the metals turned to the passive state.We cultured a cell line (NA cells) on the titan plate and another dental alloy in plastic dish. The two metals were electrically contacted in one dish, and not contacted in control dish. The cell attachment to the metals were inhibited in electrically contacted dish.
