The incorporation of self-ligating brackets into routine clinical practice aims to improve clinical efficacy. Reduction of frictional losses and improved torque transmission are characteristics attributed to these systems. This lecture presents experimental, theoretical and clinical work performed to compare self-ligating with conventional bracket systems.
Frictional losses critically depend on active or passive self-ligation; active self-ligating brackets show significantly higher friction than passive self-ligating brackets
Self-ligating brackets do not reduce force systems; forces and moments are dominated by the wires used in the brackets
Active self-ligating brackets show higher leveling efficacy than passive self-ligating brackets
