The swing-lock removable partial denture (RPD) can address some specific partially edentulous situations better than conventional partial denture designs. The concept is recommended for maximizing stability and retention by access to more tooth surfaces and undercuts with the unique clasping mechanism offered by the incorporation of lock, hinge, and gate assemblies. Since its introduction, the swing-lock RPD has gained some degree of acceptance. However, it is infrequently used by clinicians because it is technique-sensitive, especially during hinge and lock fabrication, and the durability of the retentive element of the locking mechanism decreases with the progressive wear of the metal latch attachment. This article presents a new design for a swing-lock RPD by use of a vertical bar and plastic clip attachment as an alternative to the hinge and latch attachment. The suggested modification in the locking mechanism may overcome some of the problems associated with the conventional swing-lock RPD.
摆动锁扣式可摘局部义齿（RPD）在处理某些特定的牙列缺损情况时，比传统的局部义齿设计表现更佳。这一设计理念通过利用锁、铰链和门组件所提供的独特扣合机制，接触更多的牙面和倒凹，从而实现稳定性和固位力的最大化。自问世以来，摆动锁扣式RPD已获得了一定程度的认可。然而，临床医生很少使用它，因为它对技术要求较高，尤其是在铰链和锁的制作过程中，而且随着金属锁扣附件的逐渐磨损，锁定机制固位元件的耐用性会降低。本文提出了一种新型摆动锁扣式RPD的设计，采用垂直杆和塑料夹附件替代铰链和锁扣附件。所建议的锁定机制改进可能会克服与传统摆动锁扣式RPD相关的一些问题。
