Which of the following is NOT a method for generating orthodontic forces in teeth?

Drilling is the method that does not generate orthodontic forces in teeth. In orthodontics, the objective is to apply controlled forces to the teeth to move them into desired positions, which is achieved through various mechanical means that create consistent and directional forces.

Wire deflection involves bending orthodontic wires, which creates an elastic force that can move teeth as the wire returns to its original form. Springs, like coil springs and push springs, are also used to apply force; they expand or compress to generate a pushing or pulling action on teeth. Elastics, or rubber bands, are often employed to connect different components of orthodontic appliances, facilitating shifted force application between teeth and helping to guide teeth into alignment.

In contrast, drilling is a surgical technique used in various dental procedures, primarily for removing decay, preparing cavities, or placing implants, and does not pertain to the application of orthodontic forces. It does not facilitate tooth movement and thus is not considered a method for generating orthodontic forces.
