What is the function of labial hooks in orthodontics?

Labial hooks play a crucial role in orthodontic treatment by providing a means to attach interarch elastics, which are used to correct malocclusions by connecting different parts of the dental arch. These hooks are typically located on the brackets of orthodontic appliances, allowing for the effective placement and anchoring of elastics that apply gentle force to align teeth and improve jaw positioning.

Their primary function is to facilitate the movement of teeth, making them an essential tool for achieving optimal orthodontic outcomes. The use of interarch elastics, connected via labial hooks, allows orthodontists to enhance the effectiveness of treatment by applying consistent pressure to the teeth, guiding them into their desired positions over time.

In contrast, other options focus on aspects such as stability of the arch, headgear support, or aesthetic improvements, which do not accurately describe the specific purpose of labial hooks in orthodontics.
