Abstract
Purpose: The purpose of this study is to analyze the fitness of heat - pressed ceramic laminate veneers fabricated using the additive manufacturing.
Methods: Impression was replicated by using light body silicone and heavy body silicone on the custom tray, and it was fabricated using Type Ⅳ Stone. The test specimens were prepared by using a dental scanner, a laminating veneer using a dental design program, and a specimen with a 3D printer . The control specimens were prepared by the lost wax technique and heat - pressed to fabricate the specimens. The data of the specimens were measured by the RMS value of the internal fitness a using a 3-dimensional measurement program.
Results: The Stereolithography laminate veneer group was measured at 78.10(4.09) μm and the LWV group was measured at 31.50(5.10) μm. There is a significant difference between the two groups (p<0.001)
Conclusion : Evaluation of fitness laminate veneers was fabricated by additive manufacturing showed the difference statistically significantly and clinically acceptable result.
