Several studies have shown that swinglock removable partial dentures are effective for stability of the abutment teeth and the surrounding tissues including alveolar bone. This efficacy has been thought to be due to the dynamic structure of the swinglock attachment. Individual biting force was measured to determine the physiological efficacy of teeth splints by use of the attachment. The results showed that individual biting forces with the swinglock removable partial denture were 10-25% higher than those without the denture. Furthermore, statistical analysis showed that the individual biting forces with the swinglock removable partial denture were significantly higher. The swinglock attachment can stabilize partially edentulous dentition by splinting all residual teeth. In addition, when physical forces are applied to the abutment teeth and the artificial teeth, this attachment can deliver and distribute the stress to the other abutment teeth and alveolar mucosa. The present findings suggest that the swinglock attachment augments the ability to withstand physical forces such as those occurring during biting and mastication.
多项研究表明，锁扣式可摘局部义齿对基牙及包括牙槽骨在内的周围组织的稳定性有效。这种功效被认为是由于锁扣式附着体的动态结构。通过使用该附着体测量个体咬合力，以确定牙夹板的生理功效。结果显示，佩戴锁扣式可摘局部义齿时的个体咬合力比不佩戴义齿时高10% - 25%。此外，统计分析表明，佩戴锁扣式可摘局部义齿时的个体咬合力显著更高。锁扣式附着体可通过固定所有余留牙来稳定部分牙列缺失的牙列。此外，当对基牙和人工牙施加物理力时，这种附着体可将应力传递并分散到其他基牙和牙槽黏膜。目前的研究结果表明，锁扣式附着体增强了承受诸如咬合和咀嚼过程中产生的物理力的能力。
