Abstract

Aim: The propose of this study was to calculate the amount of force that the SPRING deliver after variable degree of ACTIVATION. Material & Method: A specific designed program in Pascal language was employed to calculate the forcedelivered by each SPRING considering relevant variables such as cross section wave length and SPRING design.Results: The amount of force per each degree ACTIVATION of 3 different SPRINGs currently used in removable orthodontic appliances was calculated. Stainless steel, Z SPRING with round cross section, 0.5 mm diameter and 1.5 turn helix delivered 45,52,59 gr force when activated at 14, 15, 16 degrees respectively.Conclusion: Useful ranges of force delivery can be achieved with 0.4 mm cross section for finger SPRING and 0.5 and 0.6 mm for Z-spring.
