Moment to force ratio in orthodontics

How to vary the moment to force ratio in orthodontics. By just changing the point of application, we change the relationship between translation and rotation.
Simple but nice to know.

Hi Doc. According to your video, the M/F will ALWAYS be equal to the distance from the force applied to the center of resistance. The actual M/F that we use is a ratio between the force applied to move a tooth (F) and the counterbalancing moment produced by the couple used to control root position (M), which will determine the type of tooth movement that we will achieve.

Yes. moment equals f times d. So if you want translation you need a counter moment where the ratio is equal to d
