Background: The purpose of this study was to compare changes in the facial vertical dimension in patients after the extraction of maxillary and mandibular premolars.
Materials and methods: The pre and post treatment records of 20 patients of age range 18-25 years who had skeletal class II with hyperdivergent facial form and have undergone maxillary and mandibular first premolar extractions for orthodontic treatment under Roth prescription were taken.
Results: There was significant increase seen in the maxillo-mandibular plane (MM angle) and Steiner’s SN (Go-Gn) angle of pre and post treatment cephalometric records.
Conclusion: The results of this study showed that stress should be given on incisor intrusion and extrusion of molars should be avoided to prevent further increase in vertical dimensions in vertical growers.
