The use of blocked-out duplicate casts in the fabrication of temporary removable partial dentures has been described. Temporary removable partial dentures produced in this controlled manner fit properly and aid in minimizing intraoral damage. Accuracy of fit is assured because all relief is accomplished by block out on the surveyor during the laboratory phase rather than by random grinding of the prosthesis at insertion. In addition, the original cast is salvaged and can be used as a meaningful reference during the finishing process in the laboratory (Fig. 5).
已经描述了在制作临时可摘局部义齿时使用封闭的复制模型。以这种可控方式制作的临时可摘局部义齿贴合良好，有助于将口腔内损伤降至最低。由于所有的缓冲都是在实验室阶段通过在观测仪上进行封闭来完成的，而不是在义齿就位时随意打磨，因此可以确保贴合的准确性。此外，原始模型得以保留，并且在实验室的修整过程中可用作有意义的参考（图5）。
