PURPOSE. This study was conducted to compare the marginal and internal fit of all ceramic crown using the replica technique and the triple-scan protocol.

MATERIALS AND METHODS. Twenty zirconia ceramic crowns were fabricated using titanium abutment model. All crowns were divided into two groups of 10 each, depending on the replica technique and the triple-scan protocol. The internal and marginal fit of 10 zirconia ceramic crowns were measured at 17 points for each specimen using the replica technique. The other 10 ceramic crowns were measured using the triple-scan protocol. Statistical analysis was performed by t-test (¥á= .05).

RESULTS. The mean and standard deviation of marginal and internal fit were significantly different between the replica technique (49.86 ¡¾ 29.69 §­.) and triple-scan protocol (75.35 ¡¾] 64.73 §­., P<.001). The mean and standard deviation of internal fit except marginal fit were 58.38 ¡¾! 31.77 §­ and 64.00 ¡¾z 46.43 §­., respectively (P>.343).

CONCLUSION. There was a statistically significant difference in the marginal fit measured by the two methods. However, there was no statistically significant difference in the internal fit between the two methods.
