Comparative Evaluation of Frictional Resistance of Three Different Types of Passive Self-ligating Ceramic Brackets Using Coated and Uncoated Stainless Steel and Nickel Titanium Arch Wires: An In Vitro Study

Ab s t r Ac t Aim: The present study was aimed to evaluate and compare the frictional characteristics of three newly introduced passive ceramic self-ligating brackets (SLBs), Damon clear, Truklear, and Cabriolet, using coated and uncoated stainless steel (SS) and nickel titanium (NiTi) archwires. Materials and methods: Fifteen maxillary right central incisor brackets of dimension 0.022” × 0.028” slot: five brackets, each of Damon Clear, Cabriolet, and Truklear brackets. Thirty coated and uncoated SS and NiTi archwires were part of the study. Results: The frictional resistance (FR) with three different passive self-ligating ceramic brackets was studied using three different types of SS and NiTi archwires based on their coating. The Damon Clear bracket showed less FR, while the highest FR was observed for the Truklear bracket when using various types of NiTi archwires; the Truklear bracket showed less FR, while the highest FR was observed for the Cabriolet bracket. Conclusion: FR with three passive SLBs when carried out with the Damon Clear bracket showed less FR, while the Truklear bracket showed the highest FR; and when the study was carried out using NiTi archwire, the Truklear bracket showed less FR, while the Cabriolet bracket demonstrated the highest FR.
