| Research Abstract |
Dental alloys were deposited with ALD (atomic layer deposition) methods using SiO2 and Al2O3 and are examined whether ALD deposition on the surface could reduce the elemental ions from alloy surfaces. The SiO2 deposition could not reduce the elemental ion release, however Al2O3 deposition could reduce the elemental ions from the alloy surfaces. In addition, the surfaces demonstrated the blue-white color on the surface. This meant that the ALD deposition would beneficial for orthodontic wires to hide metal color for clinical application. After the orthodontic alloy wires were deposited with Al2O3, frictional properties were examined. There were no difference in friction forces between control and experimental groups.
