An innovative fixed partial denture design for restoring a posterior edentulous space is described. The distal retainer is conventionally luted with a zinc phosphate cement, and the mesial retainer is luted with a resin cement. Contingency planning, which involves placement of a nonrigid connector between the pontic and the distal retainer, allows recementation of the resin-luted segment if the resin bond fails.
本文描述了一种用于修复后牙无牙间隙的创新性固定局部义齿设计。远端固位体传统上用磷酸锌水门汀黏固,而近端固位体用树脂水门汀黏固。应急计划包括在桥体和远端固位体之间放置一个非刚性连接体,以便在树脂黏结失败时能够重新黏结树脂黏固部分。
