| Abstract | ||
| Background: kinetic friction force (KFF) between the orthodontic brackets and wire impacts to the sliding mechanics that affecting teeth movements and treatment duration. This sliding media is released metal ions from the fixed appliances. This study aimed to assess the KFF and surface topography of stainless steel and I archwires in dry conditions and in media fully with metal ions that released from fixed appliances. Methods: In this research study, a set of 60 as-received straight archwires specimens (50 mm) length wire were employed and categorized into two groups based on the material type (30 super elastics new I archwires gauge (0.4572 x 0.3556 inch) and 30 stainless steel archwires 0.4572 x 0.5588" as a control (. The archwires' KFF was measured while sliding a loaded Roth Stainless Steel brackets (0.4572) on the archwire using a universal tensile testing machine in dry and metal ions released media. While the topography surface was assessed using a noncontact Atomic Force Microscope. Results: KFF of I arch wire was significantly lower than SS wire in dry condition. Metal ions media released from fixed appliance significantly reduced KFF compared to dry condition for both wires. surface roughness reports revealed that the highest mean of all three roughness parameters was in SS group, followed by I arch wires in descending order. Additionally, Metal ions media significantly reduce all roughness parameters. Conclusion: KFF of I archwire lesser than SS standard archwire in all conditions specially in ion media. Full ion media reduce KFF for both tested wires. | ||
