Complete dentures were made for 30 patients. Fifteen sets were processed by conventional compression molding and 15 sets were processed by using the SR-Ivocap injection system. Changes in vertical dimension between the waxed and processed dentures were measured at the incisal guide pin by using a dial indicator. The difference between the two methods was highly significant on the basis of t-test statistics. Whereas the processing changes noted with the conventional pack-and-press method were similar to previous studies, the injection method produced little or no pin opening. The superiority of the injection method before decasting was indisputable, and the results suggest that the laboratory remount procedure may be unnecessary when this system is used.
为30名患者制作了全口义齿。15副通过传统压缩成型工艺制作,15副通过使用SR-Ivocap注射系统制作。使用表盘指示器在切导针处测量蜡型义齿和加工后义齿之间垂直距离的变化。基于t检验统计,两种方法之间的差异非常显著。传统的装盒加压法所记录的加工变化与先前研究相似,而注射法产生的针孔开口很小或没有。在脱模前注射法的优越性是无可争议的,结果表明当使用该系统时实验室重新上架程序可能没有必要。
