[Influence of die spacer on the marginal gap of partial crowns].
The effect of die spacer in the fabrication of partial crowns was examined in an in vitro study. Even with good overall expansion of the investment material it is impossible to prevent tight spots in the areas of the box form or clasp retentions. These have to be removed by grinding. Accurate application of die spacer may improve the marginal fit significantly while reducing the amount of grinding necessary.
