title: Floating norms as guidance for the position of the lower incisors.
abstract: 1. The incisor position should be evaluated in relation to the sagittal and vertical configurations of the face, as well as to the shape of the bony chin. 2. A floating norm for the positioning of the lower incisors is established based upon the guiding variables ANB, ML-NL and the N angle with the introduction of a multiple regression equation. The anticipated values for the guiding variables at the end of the treatment are used in the calculation.
