Purpose : To understand the impact on the strength or restoration force by the change of heating temperature when soldering 18-8 stainless steel round wire which is the chrome-nickel class for dental orthodontic device production.
Methods : The following conclusions were made upon the results from tensile strength test, 3 point bending test, and 90° bending fatigue test with 24 samples that had been applied with condition 1 (before heat treatment -natural) and condition 2 (after heat treatment - mooring 30 seconds after heating up to 500 , 700 , and 900 )to 0.4 , 0.7ß , 18-8 stainless steel round wire (spring hard) by Jinsung Company.
Results : When it was heat-treated at 900 , both 0.4 and 0.7 showed very low tensile strengths compared to the heat treated cases at 500 and 700 Yield strengths of both 0.4 and 0.7 showed very low compared to the heat treated cases at natural, 500 , and 700 , as well. Upon the results of 3 point bending test, the heat treated case at 900 showed very low in both 0.4 and 0.7 , compared to the heat treated cases at natural, 500 , and 700 . Tensile strength of both 0.4 and 0.7 as well, showed very low compared to the heat treated cases at natural, 500 , and 700 . Upon the results of 90° bending fatigue test, the heat treated case at 900 showed the highest wave node resistance in both 0.4 and 0.7 .
Conclusion : This study concluded that heating temperature change during wire soldering impacts on the characteristics of orthodntic wire.
