| Outline of Final Research Achievements |
Dental alloys were coated with PLD (Pulse Laser Deposition) method using alumina, TiO2 and SiO2. The alumina coating demonstrated the blue-white color. TiO2 coating showed right gold, green and purple color. SiO2 coating demonstrated blue-silver color. These results indicated that the PLD deposition would beneficial for orthodontic wires to hide metal color for clinical application. After the orthodontic alloy wires were deposited with alumina, frictional propertied were examined. These were no difference in friction forces between control and experimental groups.
