Abstract |
The authors measured orthodontic force using the orthodontic materials of the Rocky Mountain Products Company. The results were as follows :
① Use latex of wide diameter in long distance, and when the latex of wide diameter activated by four or five times, we obtained a optimal force.
② The authors obtained canine retractions with sectional arch. Activation of sectional arch began at 1mm and had to do not activations of 3mm more.
③ The leveling started from .014 green round wire and finished to. 0.16" green Elgiloy round wire. Permit only a mild force in ideal arch form, in rectangular wire.
④ Fundamentaly, elastic thread obtained maximum force by activating as two times.
⑤ Coil spring obtained more heavy force from short distance than long distance. |
