Therefore, an orthodontist mostly pays attention to how and to what extent the positions of lips and orthodontics are related. In fact, an orthodontist employs the cone beam computed tomography (CBCT), laser scanners, and structural stereophotogrammetry for 3D imaging of soft oral tissues.

Moreover, some therapeutic-orthodontic solutions such as the extraction premolars can cause changes in soft tissues of the face.

How Are the Positions of Lips Measured in Orthodontics?

In 1968, Rickett introduced a value orthodontics reference called the E-line, which stretches from the tip of the nose to the tip of the chin. Orthodontists prefer that the lower and upper lips be nearly 3 mm and 5 mm away from the E-line.
