A universal approach for fabricating abutment crowns for existing removable partial dentures is described. A replica (analog) of the clasp assembly is generated and transferred to a traditional working cast, which includes the abutment die. The analog is incorporated into the working cast as a removable component to allow the formation of the crown contours. The article reviews in detail the procedures required to transfer accurately all the essential components and information from the mouth to the working cast while allowing the patient uninterrupted use of the removable partial denture. Prestabilizing the removable partial denture, creating the analog impression, avoiding errors due to soft tissue components, forming a precise analog base, selecting materials, generating a rigid resin analog, and prescribing a path of insertion and withdrawal to the analog are described. The method replicates all types of clasps and can generate all types of fixed prosthodontic retainers to function harmoniously with the existing partial denture.
本文描述了一种为现有可摘局部义齿制作基牙冠的通用方法。制作卡环组件的复制体（代型）并将其转移到传统工作模型上，该工作模型包括基牙模型。该代型作为可移除部件并入工作模型，以形成牙冠轮廓。本文详细回顾了将所有基本部件和信息从口腔准确转移到工作模型，同时让患者不间断使用可摘局部义齿所需的步骤。文中描述了可摘局部义齿的预稳定、制作代型印模、避免软组织部件导致的误差、形成精确的代型基座、选择材料、制作刚性树脂代型以及为代型规定就位和取出路径。该方法可复制所有类型的卡环，并能制作所有类型的固定义齿固位体，使其与现有的局部义齿和谐配合。
