Abstract

Introduction: Background: No two cases are alike. Different cases, different treatment approach. Class II div 1 malocclusion possesses a variety of conflicting treatment modalities. What is important to know is “ what suits a case best.”

Materials and Methods: In this study a comparative analysis is presented for 2 cases of class II malocclusion. For one, upper first pre molars are extracted. The second case was treated with fixed functional Herbst appliance. The decision to extract or not to extract depends on proper examination of the case and visualizing the outcome beforehand.

Purpose: The purpose of this article was to compare the outcome of treatment with modified Herbst and bilateral upper first premolar extractions in post pubertal patients with Class II malocclusion.

Keywords: Class II; Adolescence; Acrylic Herbst; Premolars Extraction
