Purpose: The purpose of this study was to impact of force system change in finger spring that add helical coil one round on orthodontic force. Methods: The following conclusions were drawn from the experiment conducted after bending 90 samples with a CNC wire forming machine while changing the height and lumen size to 1 - 3 - 5 and 2 - 3 - 4 respectively in the coil of the force system in finger spring added with one wheel of helical coil of 18-8 stainless steel round wire (Φ0.5 , spring hard) from Jinsung Co. in domestic market under the following conditions: Laboratory name = Instron 5942; Temperature(deg ) = 18.00; Humidity(%) = 50.00; Rate 1 = 10.00000 /min; Compressive extension = 5.0 . Results: When Coil height is 1, 3, 5 and lumen size is 2, 3, 4 reduce finger spring as mean value of compressive extension occasion maximum load(mN) increases as coil height rises, and lumen size grows to 5.0 . And was expose that compressive load(mN) increases as coil position of finger spring rises and increase as lumen size is decrescent. Conclusion: As the adherence height of coil was raised from 1mm through 3 to 5 , compressive load increased. As the lumen size increased from 2 through 3 to 4 , compressive load decreased. Therefore, these results suggest that it is desirable to lower the coil height and enlarge the lumen size to enhance the biomechanical efficiency of finger spring when manufacturing the finger spring for removable orthodontic devices
