Abstract
Purpose: The purpose of this study was establishing process of manufacturing dental prosthesis by using eZIS system(DDS Inc.,Korea).
Methods: To evaluate accuracy verification, the test was practiced two ways. First, Comparison of 3D printing models and stone models was practiced by using 3D superimposing software. #36 prepared master model was scanned by eZIS system and three ‘Veltz3D’ 3D printing models and three ‘Bio3D’ 3D printing models were manufactured. three stone models were manufactured by conventional impression technique. Second, Fitness test was practiced. the 3D printing models and the stone models was compared by manufacturing same resin crown. #36 prepared master model was scanned 9 times and manufactured (milled) 9 resin crowns by eZIS system. These crowns were cemented three ‘Veltz3D’ 3D printing models, three ‘Bio3D’ 3D printing models and three stone models. These crowns were sliced mesiodistal axis and gaps were measured by digital microscope.
Results: The average accuracy of Bio3D models were 65.75%. Veltz3D(Hebsiba) models were 60.11% Stone models were 41.00%.
Conclusion : This study results showed 3D printing model is similar with stone model. So it was under clinical allow, didn’t affect final dental prothesis. There were no significant differences in the appearance of the three types of milling crowns.
