A comparative evaluation of the physical properties of two orthodontic archwires

Introduction: The study aims to compare selected physical properties of newer grades of A.J. Wilcock (AJW) stainless steel archwires with the corresponding grades of Ortho Organizer archwires. Materials and Methods: Archwires were grouped according to grades and sizes. Similar size wires were comparatively evaluated for ultimate tensile strength, maximum load via 3-point bending, working range, kinetic friction, and surface topography. Results: The results were analyzed using paired Student's t-test, and it was observed that Ortho Organizer wires possess comparable strength and stiffness to that of the AJW wire. They present lesser working range characteristics than AJW wire. They have smoother surface but similar frictional properties compared to AJW archwire. Conclusion: Based on the study, it can be concluded that there is no significant difference between the properties of the two wires and both can be used interchangeably in clinical practice.
