Abstract
Comparison Of The Fractional Characteristics Of Conventional Vs Self-Ligating Orthodontic Brackets - An invitro Observational Study
Highlights
The orthodontic therapy lies around achievement of desired ‘tooth movement’
The fractional characteristics (FC) of orthodontic brackets is an essential factor in determining the choice of available bracketing systems and the same is linked to treatment outcomes
A 19x25 SS rectangular straight wire cut into 10mm each fragments were passed through the brackets of all these groups and FC were evaluated on an Instron universal testing machine in both wet and dry conditions
Summary
The orthodontic therapy lies around achievement of desired ‘tooth movement’. The tooth movement essentially occurs when the applied forces adequately overcome the generated friction at the bracket-wire junction.[1]. The forces applied and treatment outcomes are dependant on factors such as the bracket type/ material, wire alloy, wire dimensions, the method used for ligationand torque angulation (at junction of bracket slot – wire).[1]. This significant influence of friction in orthodontics had led to increase in research for surface evaluation to determine the frictional characteristics. Conclusion: The current study demonstrated that Damon Q brackets to have least frictional characteristics They were followed by empower self-ligating bracket, Smart clip self-ligating brackets, synergy brackets, metal brackets, ceramic brackets in the same order for both wet and dry conditions
