The content and distribution of metallic ions on the surface of gold-plated brass screwposts (Dentatus and MecOdont) were analyzed by X-ray microanalysis. On screwposts from one of the manufacturers the protective outer layer of gold was found to be localized to specific areas of the posts, i.e. the grooves, while unprotected Cu-Zn alloy was found on the ridges. The results are discussed with regard to results on root posts published earlier. Screwposts constructed in this way would appear to be of doubtful clinical value.
通过X射线微量分析，对镀金黄铜螺纹桩（Dentatus和MecOdont）表面金属离子的含量和分布进行了分析。在其中一个制造商生产的螺纹桩上，发现金的保护性外层局限于桩的特定区域，即凹槽，而在脊上发现了未受保护的铜锌合金。结合早期发表的关于桩核的研究结果对这些结果进行了讨论。以这种方式制造的螺纹桩临床价值似乎存疑。
