Abstract
With the steady increase of the number of adults undergoing orthodontic treatment, there has been a corresponding increase in demand for more esthetic orthodontic appliances. The purpose of this study is to determine the friction value of esthetic wires compared to conventional stainless-steel wire, the bending capacity, and the relationship between the coating layer’s composition and the friction value, using different types of ceramic brackets with metal reinforced slot, in combination with a metal bracket as a control group. Materials and methods: Four types of brackets (Clarity 3M Unitek, GAC, TP, GAC metal) were coupled with ten different types of arch wires: 0.016” round conventional stainless steel, 0.016” round (Denturum) stainless steel, 0.016” round (Ortho technology) stainless steel, 0.016” round (G&H) stainless steel, 0.016”x0.022” rectangular conventional stainless steel, 0.016”x0.022” rectangular (Denturum) stainless steel, 0.016”x0.022” rectangular (Ortho technology) stainless steel, 0.016”x0.022” rectangular (G&H) stainless steel, 0.0018”x0.022’’rectangular (G&H) stainless, and 0.018”x 0.022” rectangular (Ortho technology) stainless steel. After testing, penetration through the coating layer was observed in all specimens, and the frictional coefficients were still within the limits outlined by conventional orthodontic wire bracket couples.
