Distortion of wax crown patterns is unavoidable. This distortion is sufficient to reduce the fit of the final restoration to a degree that is clinically unacceptable. The wax distortion may be ignored only by use of die-investing technique. However, an ideal investment for this technique is at present not available.
蜡冠模型的变形是不可避免的。这种变形足以将最终修复体的贴合度降低到临床无法接受的程度。只有采用代型包埋技术才能忽略蜡的变形。然而，目前尚无适用于该技术的理想包埋材料。
