A passive fit is an important prerequisite for implant-supported prostheses. It limits the amount of stress transferred to the bone-implant interface and ensures long-term osseointegration. A simplified technique is proposed for the fabrication of passive bar-supported implant overdentures. The use of titanium industrial components enhances the precision of fit, and the passivity is achieved with an intraoral luting sequence and laser welding. The method is quick and standardized, and does not require sophisticated steps. This article shows the results of 7 cases 18-24 months (mean 21.4) after the loading of cases.
被动适合性是种植体支持修复体的重要前提条件。它限制了传递至骨-种植体界面的应力大小，并确保长期骨结合。本文提出了一种用于制作被动杆式支持种植覆盖义齿的简化技术。使用钛工业部件可提高适合精度，通过口内粘结步骤和激光焊接实现被动适合性。该方法快速且标准化，无需复杂步骤。本文展示了7例病例在加载后18至24个月（平均21.4个月）的结果。
