Abstract

An orthodontic treatment that involves uprighting of deep horizontally impacted mandibular second molars (MM2) can be a challenging procedure. This case report demonstrates an approach to correct an impacted MM2, specifically in a 21-year-old male patient who presented with a Class II division 2 malocclusion, deep bite, and bilateral maxillary second molars with buccal crossbite. Correction of the impacted MM2 had been achieved using a ramus temporary anchorage device (TAD), which applied pulling and extruding forces along with an uprighting moment. Addressing the deep bite required proclination of incisors, utilization of an intrusion arch for maxillary incisors, and implementation of two subapical TADs for mandibular incisor intrusion. This entire treatment was completed in 29 months and the patient was satisfied with the result.
