What type of movement is produced when force is applied to the crown of a tooth?

When force is applied to the crown of a tooth, it results in tipping or rotational movement. This occurs because the crown, which is the visible part of the tooth above the gum line, acts as a lever. When force is directed at the crown, the tooth will typically move around its root as a pivot point. This tipping motion allows for gradual repositioning of the tooth within the dental arch.

In orthodontics, this concept is fundamental when applying forces with braces or other orthodontic appliances. The mechanics of tipping movement are particularly important for getting teeth into proper alignment and achieving the desired occlusion. By understanding this type of movement, orthodontists can predict the effects of various forces and design treatment plans that will effectively move teeth into their ideal positions.
