Abstract
Purpose: This study was to observe the surface and interfacial characteristic of Zirconia by surface treatment. And it was observed the roughness and contact angle according to processing, and the interfacial properties by surface treatment on zirconia.
Methods: The oxide formation and ion diffusion between core and veneer ceramic were determined by the X-ray Dot Mapping of EPMA(Electron probe micro analyzer). The roughness was measured by 3D Digital microscope and the contact angle according to processing of zirconia was observed using distilled water on the surface.
Results: The surface roughness of the specimens Z04, Z12, Z15 was measured 0.67(±0.03)um, 0.50(±0.12)um, 0.35(±0.09)um, respectively. As results of contact angle test, Z04, Z12, Z15 of specimen group without binder treatment was measured 46.79(±3.17) , 57.47(±4.83) , 56.19(±2.66) , respectively. but, L04, L12, L15 of specimen group without binder treatment was measured 63.84(±2.20) , 66.08(±0.16) , 65.10(±1.01) , respectively. Average contact angle of L15 was measured 65.10(±1.01) . In X-ray Dot Mapping results, thickness of binder including Al element was measured that each of L04, L12, L15 were 20um, 15um, 10um.
Conclusion: The more rough surface increases the wettability, but the sintered exclusive binder decreases the wettability.
