The Michigan Computer Graphics Coordinate Measuring System was used to determine the influence of denture teeth on the accuracy of processed denture bases. Three different processing methods--compression molding, injection pressing, and vacuum-assisted resin pouring--were used. The presence of denture teeth was determined to affect the accuracy of the processed denture bases of all three techniques. For denture bases without teeth, the compression-molding technique demonstrated significant differences in accuracy; however, no significant differences were found in the injection-pressed or resin-poured denture bases.
密歇根计算机图形坐标测量系统被用于确定义齿对加工后义齿基托精度的影响。采用了三种不同的加工方法——压缩成型、注塑压制和真空辅助树脂灌注。结果确定义齿的存在会影响所有这三种技术加工后义齿基托的精度。对于无牙的义齿基托，压缩成型技术在精度上表现出显著差异；然而，注塑压制或树脂灌注的义齿基托未发现显著差异。
