Intraosseous Transmigration of Mandibular Premolar into the Mandibular Ramus: A Case Report

Abstract

Background: Literature survey indicates that intraosseous transmigration is uncommon. Transmigration of mandibular premolars to distant sites like the ramus are rare and is often detected by chance. Case description: A 19-year-old female reported seeking replacement of her missing teeth. Clinical examination showed multiple missing teeth and a history of early loss of permanent molars. Panoramic radiographs revealed a transmigrated mandibular premolar in the ramus of the mandible surrounded by well a circumscribed radiolucent area. Practical implications: Transmigrated premolars in the ramus can cause complications like cystic lesions, weakened ramus, and susceptibility to fracture. Young females undergoing early extraction of permanent molars are at increased risk.
