[The determination of the optimal individual position of the mandibular anterior teeth]

Determining the individually optimal position of the lower incisors is one of the important factors in diagnosis and treatment planning. The study compares the accuracy of a number of methods postulated by different authors. It clearly shows that regression models display the highest accuracy in predicting the optimal incisor position. The most important variables in the prognosis are ANB angle and the prominence of the chin as measured by the distance of pogonion to NB line. The best regression model is presented as a formula and in a graphical representation.
