What will result when a single force is applied at the center of resistance?

When a single force is applied at the center of resistance, the most significant result is translation. The center of resistance is described as the point through which a force creates motion in the most efficient and predictable manner. When a force is applied at this point, it does not create any rotational movement or tipping, but rather allows for the entire object or tooth to move along a straight path in the direction of the applied force.

In orthodontics, understanding the concept of the center of resistance is fundamental for achieving desired movements of teeth. When force is applied directly at this center, it enables the translation of the tooth, which means the tooth moves in a straight line without any change in its angulation or tilt. This predictable, linear movement is essential for achieving optimal alignment and positioning of teeth during orthodontic treatment.
