The use of a hinge for a removable partial denture with an opening labial bow was replaced by the design and construction of a flexible plate incorporated as part of a cobalt-chromium casting.
Three similar prostheses were constructed and tested in vitro on an endurance test machine. Each test piece completed 12,000 opening and closing operations without fracture, which a previous study showed is a probable life cycle of a typical removable partial denture with a hinged section.
This plate provided sufficient flexibility to allow functional operation of the removable partial denture by a patient.
带有开口唇弓的可摘局部义齿的铰链使用，已被作为钴铬铸件一部分的柔性板的设计与制作所取代。
制作了三个类似的修复体并在体外耐力试验机上进行测试。每个试件完成了12000次开合操作而未发生断裂，先前的一项研究表明这是一个典型的带有铰链部分的可摘局部义齿可能的生命周期。
该板提供了足够的柔韧性，以使患者能够对可摘局部义齿进行功能性操作。
