A simple technique for fabricating stud overdenture retainers in the form of custom attachment castings with teflon retention discs has been described. This system allows for selective placement of the retention sphere on the root surface and control of retention through the size of the retention sphere. Using transfer location projections, exact transfer of the castings to the working model is possible. When necessary, the teflon discs may easily be replaced at the chairside.
已经描述了一种以带有聚四氟乙烯固位盘的定制附着体铸件形式制作桩核覆盖义齿固位体的简单技术。该系统允许在牙根表面选择性地放置固位球，并通过固位球的大小控制固位力。使用转移定位凸起，可以将铸件准确地转移到工作模型上。必要时，聚四氟乙烯盘可在椅旁轻松更换。
