Orthodontic Management of Impacted Mandibular Second Premolar (Tooth 45) Using the Edgewise Technique – A Case Report

Abstract

Abstract

Introduction: Impacted teeth represent a common clinical challenge in orthodontic practice due to their potential to disrupt normal occlusion and oral function. Objective: This case report aims to present the orthodontic management of an impacted mandibular second premolar (tooth 45) using the Edgewise technique to restore proper alignment and functional occlusion. Case Report: A 14-year-old female presented with Class I dentoskeletal malocclusion, severe crowding in the mandibular arch, midline shift, and an impacted tooth 45. Extraoral examination revealed a convex facial profile with slight asymmetry. Treatment was conducted using the 0.022-inch Standard Edgewise system. Leveling and aligning were initiated using multiple loop stainless steel archwires. Space creation for tooth 45 was achieved using an open-coil spring combined with molar distalization and anterior flaring, followed by uprighting and traction of tooth 45 into the dental arch. Conclusion: Comprehensive orthodontic treatment using the Edgewise technique with open-coil mechanics successfully uprighted and aligned the impacted tooth 45, establishing a stable Class I canine and molar relationship with improved smile aesthetics.
