Background: The aim of the study was to compare and evaluate the frictional resistance of clarity advanced ceramic brackets, metal insert ceramic bracket, and conventional metal brackets with Nickel–titanium wire and stainless-steel archwire of varying dimensions. Materials and Methods: The sample size with 80% power was 45. The samples were divided into three groups each group consisting of 15, Group 1 – Clarity Advanced Ceramic Brackets (3M Unitek). Group 2 – Metal insert Ceramic Brackets (3M Unitek). Group 3 – Conventional Metal Brackets, the control group (3M Unitek). The wires used for testing were 0.016” Niti, 0.017 ×× 0.025” Niti and 0.019 ×× 0.025” SS. Results: In the present study, it was found that wire material (nickel titanium) had an effect on friction. It was found that metal insert ceramic bracket exhibited similar frictional resistance when compared to metal brackets for 0.017 × ×0.025” Niti and 0.019 × 0.025” SS wires. The Clarity Advanced bracket had the highest frictional resistance followed by metal insert ceramic and least with the conventional metal. Conclusion: Clarity advanced can be the bracket of choice for the esthetically discerning patients who do not require extraction for orthodontic reasons, but the high frictional resistance in relation to larger rectangular Niti archwires should be considered. In adult patients who require extraction in the treatment plan, metal insert ceramic brackets are definitely a pleasing alternative when compared to metal brackets.
