A prefabricated Thompson dowel rest semiprecision attachment system for distal-extension removable partial dentures deserves consideration in the treatment planning of periodontally involved dentitions. It is a system that provides for rotation and therefore stress-breaking with controlled movement. Many other stress-breaking systems provide for rotation without specific control. In addition, the Thompson dowel rest system is the only stress-breaker that is intracoronal not extracoronal. This prefabricated system offers facilitation of laboratory procedures, eliminates the need for utilization of gold for dowels, reduces the size of the rest seats, and aids in the preservation of the integrity of the hard and soft supporting tissues.
一种用于远中游离可摘局部义齿的预制汤普森桩核支托半精密附着体系统，在牙周受累牙列的治疗计划中值得考虑。该系统允许旋转，从而通过可控运动实现应力中断。许多其他应力中断系统允许旋转但没有特定控制。此外，汤普森桩核支托系统是唯一的冠内而非冠外应力中断器。这种预制系统便于实验室操作，无需使用金制作桩核，减小了支托窝的尺寸，并有助于保持软硬支持组织的完整性。
