Purpose: This study was aimed to compare the margin and internal fitness of single anterior all-ceramic crown zirconia core made by three deferent CAD/CAM systems.

Material and methods: Five single zirconia cores were manufactured by three deferent CAD/CAM systems(Cerasys¢çsystem, KaVo Everest¢çsystem, Lava¢â system). The manufactured zirconia cores were duplicated through the use of replica technique, and a replicated sample was sectioned in the center of bucolingual and mesiodistal direction to measure the marginal and internal gap. Measurement was carried out by using measuring microscope (AXIO¢ç) and I-Solution¢ç and analysed through the use of ANOVA.

Results: As for the mean marginal fitness of the zirconia core, it was 84.74 ¡¾ 27.57 ¥ìm, in Cerasys¢ç, 80.23 ¡¾ 21.07 ¥ìm in KaVo Everest¢ç and 96.37 ¡¾ 11.45 ¥ìm in Lava¢â, and as for the mean internal gap, it was 94.11 ¡¾ 30.07 ¥ìm in Cerasys¢ç, 92.31 ¡¾ 25.18 ¥ìm in KaVo Everest¢ç, and 94.99 ¡¾ 18.74 ¥ìm in Lava¢â. There was no significant statistically deference among the total average gap of three systems. The internal gap in KaVo Everest¢ç seemed to be smaller than Lava¢â (P < .05). The internal gap in the incisal area was larger in all of the three systems.

Conclusion: There was no difference in marginal fitness in Cerasys¢ç, KaVo Everest¢ç and Lava¢â. As for the internal fitness, it was smaller in KaVo Everest¢ç system than Lava¢âsystem. In all of the three systems, there was a larger gap in incisal area. The marginal and internal gap was within the clinically allowed range in all of the three systems.
