Abstract
The casting of extensive implant superstructures that have a good passive fit may be technically demanding. A simple, 2-stage casting technique is presented that avoids common problems associated with the casting of large superstructures. The fabrication of a 7-unit metal-ceramic screw-retained fixed partial denture supported by 5 implants is used to illustrate this technique.
摘要
铸造具有良好被动适合性的大面积种植体上部结构在技术上可能具有挑战性。本文介绍了一种简单的两阶段铸造技术，该技术可避免与大型上部结构铸造相关的常见问题。以一个由5颗种植体支持的7单位金属烤瓷螺丝固位固定局部义齿的制作过程为例来说明该技术。
