The purpose of this study was to compare of marginal fitness of zirconia copings according to impression techniques and zirconia blocks. For the conventional impression, two types of rubber impression materials were used and digital impression was made by using an intraoral scanner. Zirconia copings were manufactured from three types of blocks. With each of ten zirconia copings was determined by surface roughness and marginal fitness. For surface roughness, LUXEN Smile() block was superior. And the lowest mean values and standard deviations of marginal gap for the HL specimens were for buccal, for lingual, and that of the HJ specimens for mesial, for distal. One-way ANOVA showed statistically significant difference between groups for marginal fitness(p<0.05). From the above results, the impression techniques and zirconia blocks had influence on marginal fit of the zirconia copings. Also the marginal fitness of all groups showed clinically acceptable range.
