Abstract
Purpose: This study aimed to clarify the effect of titanium processing methods on its corrosion resistance. Methods: Test specimens were prepared by using cast and milling from the ingot. Immersion tests were performed according to the JIS corrosion resistance test method in three different immersed solution: lactic acid, sodium chloride, and artificial saliva. Corrosion resistance was evaluated the amount of released elements quantitative analysis by means of ICPMS in immersed solutions, and total color change vector ( Δ E*ab) of the surface of immersed specimens. Results: The results showed lower released elements and color change vector in the cast titanium. The findings revealed that cast titanium specimens exhibited superior corrosion resistance compared to specimens of milling, contrasts with the typical behavior observed in other dental alloys. Conclusion: The conclusion drawn from the results is casting provides titanium with enhanced electrochemical stability compared to CAD/CAM milling processes.
