Evaluating the Surface Characteristics of Stainless Steel, TMA, Timolium, and Titanium-niobium Wires: An in vivo Scanning Electron Microscope Study.

Background: Recent metallurgical research and advancement in material science has benefited orthodontists in the selection of an appropriate wire size and alloy type, which is necessary to provide an optimum and predictable treatment results. The purpose of the study was to clinically evaluate and compare the surface characteristics of 16 × 22 stainless steel, Titanium molybdenum alloy, timolium, and titanium-niobium before and after placing them in a patient’s mouth for 3 months using a scanning electron microscope (SEM).
