Abstract: Introduction The Purpose of this study was to evaluate dentofacial vertical dimension alteration in patients with class II division 1 malocclusion after the first maxillary premolar extraction. MethodsThis study used 24 cephalograms each before and after treatment. Dentofacial dimension measured by Sivakumar and Valiathan method. The cephalometric measurements investigated were as follows mandibular plane angle, anterior facial height, lower anterior facial height, posterior facial height, facial height indeks, FH-U1, FH-U6, FL-L1, Fl-L6, S vertical-U1, S vertical-U6, Pog vertical-L1, Pog vertical-L6. To determine dento facial vertical dimension changes due to treatment paired t-test were performed, respectively. Results There was no change in the vertical dimension of dento-skeletal significantly between before and after treatment except on the posterior facial height, FL-L1, and S vertical-U1. Conclusion The results showed that in patients treated with extraction of two premolars, there was a significant decrease in following cephalometric measurement the posterior facial height, FL-LI and S vertical-U1.
