A technique is described that allows a removable partial denture with a broken clasp or a removable partial denture in which an abutment has been extracted to be restored by the reattachment of a new cast clasp component or a complete surveyed clasp assembly. The technique is applicable to most clasp designs and can include attachment to the acrylic denture base or the metal major connector. The technique is distinguished from other repair techniques by (1) providing a cast clasp replacement, (2) allowing the patient to retain the prosthesis during the repair, (3) generating a precisely formed surveyed clasp assembly by the laboratory, and (4) including an efficient transfer mechanism for the precision clasp created in the laboratory to be attached to the removable partial denture in the dental office. A two-step impression procedure is used to ensure proper relation of the partial denture to the abutments.
本文描述了一种技术，该技术可通过重新连接新的铸造卡环部件或完整的观测卡环组件，来修复卡环断裂的可摘局部义齿或基牙已被拔除的可摘局部义齿。该技术适用于大多数卡环设计，可包括连接到丙烯酸义齿基托或金属大连接体。该技术与其他修复技术的区别在于：（1）提供铸造卡环替换件；（2）在修复过程中允许患者保留修复体；（3）由实验室制作精确成型的观测卡环组件；（4）包括一种有效的转移机制，以便将实验室制作的精密卡环连接到牙科诊所的可摘局部义齿上。采用两步印模程序来确保局部义齿与基牙的正确关系。
