Purpose: The present study was performed to investigate the effect of abutment inclined angle on the marginal fit of zirconia all-ceramic crown. Methods: The Ti abutments with 3 different inclined angle(2°, 4° and 6°) were fabricated. The zirconia copings were fabricated for each abutment by using dental CAD/CAM system. The manufactured zirconia copings were duplicated through silicone replica technique, and a replicated specimen was sectioned in the center of buccolingual and mesio-distal axial to measure the marginal fit by using a stereo microscope. The results were analyzed using a one-way ANOVA with SPSS 22.0 for Windows(α=0.05). Results: On the bucco-lingual axial, marginal fit was the RL3(41.5±3.4㎛), RL2(44.3±4.3㎛) and RL1(47.5±5.7㎛), respectively. On the mesio-distal axial, marginal fit was the RL3(41.1±3.7㎛), RL2(45.7±5.3㎛) and RL1(46.2±4.5㎛), respectively. One-way ANOVA showed statistically significant difference between groups for marginal fit(p<0.05). Conclusion: For marginal fit of the abutments inclined angle, RL3 specimen was superior. The abutment inclined angle had influence on marginal fit of the zirconia copings. The marginal fit of each group were within clinically acceptable range.
