Missing teeth can be replaced using any of a number of methods. Patients may choose to replace missing teeth with a prosthesis that is either removable, fixed, or retained with implants. When it is necessary to replace anterior or posterior teeth, a properly designed and fabricated rotational path removable partial denture can be both successful and esthetically pleasing to the patient. However, while a patient's functional and esthetic needs can be met successfully, rotational path removable partial dentures can be more demanding for the laboratory technician to fabricate and for the dentist to seat in the mouth. Rotational path removable partial dentures frequently are overlooked as a viable means of treating missing teeth. This article reviews the principles of rotational path removable partial dentures, as well as their categories, advantages, and disadvantages, in the hope that more dentists will consider them when the need arises.
缺失牙可以通过多种方法中的任何一种来修复。患者可以选择使用可摘义齿、固定义齿或种植体固位义齿来修复缺失牙。当需要修复前牙或后牙时，设计和制作得当的旋转路径可摘局部义齿对患者来说既成功又美观。然而，虽然患者的功能和美观需求能够得到成功满足，但旋转路径可摘局部义齿对实验室技术人员的制作要求以及对牙医在口腔内就位的要求更高。旋转路径可摘局部义齿常常被忽视，未能作为治疗缺失牙的一种可行方法。本文回顾了旋转路径可摘局部义齿的原理及其类别、优缺点，希望更多牙医在有需要时会考虑使用它们。
