In orthodontics there has been a change in the treatment plan of crowding cases from extraction protocol. This was mainly due to the introduction of self-ligating bracket and temperature activated wires. Even though there are certain exceptions, the self-ligating bracket have evolved in orthodontics because of its advantages such as low friction, shorter treatment duration and increased efficacy. Damon’s self-ligating system has been in existence since 1930 but it has been well developed in the past 30 years with the introduction of newer systems. Damon’s self-ligating brackets have been designed to overcome the drawbacks of conventional bracket system and are often considered as the pinnacle of bracket technology. The main advantage of Damon’s system was low friction and shorter treatment duration. But the efficiency of the appliance is influenced by several factors such as Biomechanics, frequency of dental visits and patient comfort. The chapter will highlight the efficiency of the appliance, the various possible outcomes and its influence on the ease of orthodontic therapy.

“…[6,9,10] e disadvantages of friction also cause uncertainty in predicting the treatment results because it causes loss of useful force and consequently reduces the efficiency of orthodontic treatment. [11,12] To induce dental movements, it is necessary to apply mechanical forces in the range from 100 to 200 g on the tooth. [9,13] After applying force to the tooth, tensile movements begin, and an angle is formed between the bracket and the wire.…”

“…Besides, the risk of root resorption increases, and the treatment period is longer, leading to more pain. [9,11,12] So far, different techniques have been proposed to resolve such a problem, that is, friction between the wire and the bracket, [16] the most important of which is using wire of different shapes and sizes or different chemical compounds [17][18][19] as well as changing features of the bracket such as changing its width, the technique of making the bracket, its material, and coating the bracket using different nanoparticles, especially metal nanoparticles. [20][21][22] Metal nanoparticles have been used as solid lubricants since the 1990s.…”

Objectives: Coating orthodontic brackets with metal nanoparticles seem to affect surface roughness and friction. We aim to compare the effects of coating brackets with copper oxide (CuO), titanium dioxide (TiO2), and silver hydroxyapatite (S-HAP) on friction between brackets and various sizes and materials of orthodontic wires. Material and Methods: In this experimental study, we selected four groups of stainless steel (SS) brackets with eight orthodontic wires (SS and nickel-titanium [Niti]) in different sizes. Three groups were coated with CuO, TiO2, and S-HAP nanoparticles using dip coating. Then, we attached a 100 g weight to the wires and hung it from the universal testing machine. The wire passed through the brackets at a speed of 0.5 mm/min for 25 s. Finally, the friction between wires and brackets was compared using a two-way analysis of variance. Results: The results showed that friction of brackets coated with TiO2 was significantly lower than S-HAP (P = 0.021) and did not differ significantly between CuO and the control (P = 1). Furthermore, friction between CuO brackets was not significantly different from other groups (P > 0.05). Niti round wires had significantly lower friction with all brackets compared to 0.16 × 0.22 square inch Niti wire (p< 0.05), which, in turn, showed significantly lower friction compared to 0.16 × 0.22 square inch stainless steel (SS) wire (P = 0.008). Conclusion: Coating brackets with TiO2 and CuO nanoparticles can reduce the friction Moreover, Niti round wires show the least friction compared to rectangular or SS wires with all types of brackets.
