Abstract
The purpose of this research is to see the influence that extracting four premolars in the orthodontic treatment affects facial vertical dimension so we analyzed cephalogram before and after treatment for twenty-one adult patients who were finished orthodontic treatment.
The following conclusions were obtained
1) Anterior facial height had increase. (That is reason that mandibular first molar after treatment was uprighter and more extrusive than before treatment)
2) Overbite had increase and had correlated with the distance of madibular anterior teeth to facial plane.
3) The decrease of overbite had correlated with the distance of maxillary central incisor to facial plane.
4) The change of SN-Pog, and ANB angle.had no difference.
