Comparison of the Accuracy of Fit of Metal, Zirconia, and Lithium Disilicate Crowns Made from Different Manufacturing Techniques

Abstract

The type of crown and method of manufacturing had no effect on the marginal and occlusal gap of single posterior crown, while the method of manufacturing had a significant effect on the axial gap. The digital method produced the smallest axial fit in comparison with the other methods, while the type of crown had no effect on the axial gap.
