A STUDY ON THE FRICTION BETWEEN ORTHODONTIC BRACKETS AND ARCH WIRES UNDER SIMULATED MASTICATORY CONTACTS USING FINITE ELEMENT METHOD

LI Song et al.Faculty of Stomatology,Capital University of Medical Sciences,Beijing,100050  
Objective:To study the friction between orthodontic bracket and wire influenced by the masticatory contacts.Methods:The friction between orthodontic brackets and arch wires under simulated masticatory contacts was studied using the finite element method.Results:The frictional forces between arch wires and bracket bases decreased significantly under masticatory contacts,while the frictional forces between arch wires and bracket wings increased.Conclusion:The total frictional forces between orthodontic brackets and arch wires increased under masticatory contacts.
