N2 - NiTi is alloy that has unique properties include shape memory dan superelasticity. However, it has disadvantages which cause allergic and toxicity to the body from the Ni release. In order to reduce Ni release and increase corrosion resistance an Electropolishing Pretreatment- Photoelectrocatalytic Oxidation (EP-PEO) and Advanced Oxidation Process (AOP) coating were synthesized in order to produce TiO2. Scanning Electron Microscope (SEM) was depicted various morphologies of NiTi orthodontic wire surface. Ni release experiment in various saliva by using Inductively Coupled Plasma (ICP) was shown reducing Ni release significantly both in saliva pH 3 dan pH 6.25 in AOP coating for 2 months monitoring. This results confirmed that the Ni release was evidently decreased and the corrosion resistance significantly improved after coated with AOP.
