ABSTRACT
Objective:
To evaluate the accuracy of Cerec Bluecam and Cerec Omnicam with 3D printed resin models.Methods:
A metal master model including 4 cylindrical metal preparations on the model base,respectively simulating the maxillary canine and the first molar preparations,was prepared.The right canine and the right first molar were respectively marked as A and B,and the left as C and D.The master model was scanned respectively by Cerec Bluecam and Cerec Omnicam for 10 times,10 digital models were genera-ted in Bluecam group and Omnnicam group respectively.Resin models were obtained by a 3D printer based on the digital models,the distance of AB,AC,BD and the diameter(d)of A were respectively measured.Statistical analysis was conducted by SPSS 13.0 soft-ware.Results:
The distance of AB,AC,BD of master model and Bluecam group showed significant difference(P 0.05);the distance of AC,BD of master model and Omnicam group showed significant difference(P 0.05).All the distances of the Bluecam group and Omnicam group showed significant difference(P <0.05).Conclusion:
The scanning accuracy of Cerec Bluecam is higher than that of Cerec Omnicam in a single preparation scanning.When the scanning area ex-tending,the scanning accuracy of Cerec Omnicam is higher than that of Cerec Bluecam.
