Abstract: Introduction: The reduction of resistance to sliding between the archwire and bracket promotes more seamless tooth movement, leading to a faster and improved orthodontic treatment experience. This research aimed to examine how the degradation of elastomeric modules, different ligation methods, bracket-wire angle, and nickel-titanium wire have an impact the kinetic friction resulting from the interaction between NiTi and SS brackets. Materials and Methods: The current in vitro study was conducted on NiTi wires, with two types of ligations (O-ring, SS wire ligature) and two bracket-wire angles (0? and 10?). The kinetic friction in each group was measured using a Universal Testing Machine at four time intervals: baseline, day one, week one, and week four. Repeated measures ANOVA, and Greenhouse-Geisser test, and relevant post hoc tests were used for statistical analysis (P). Results: There is a decrease in kinetic friction in all types of ligations, which confirmed the effect of time on the degradation of ligation modules. The kinetic friction is equal in both O-ring and SS wire ligations. No difference was observed between O-ring and SS wire ligations. Furthermore, the bracket-wire angle did not affect friction. Conclusion: It is concluded that both O-ring and SS ligation can be used for ligation, as both have equal frictional resistance.
