Breaking through mandibular barrier: A case report on orthodontic repositioning of an impacted tooth

Abstract

Tooth impaction is known to cause various problems such as space loss, tipping of adjacent teeth, super-eruption of the antagonist tooth, and dislocation of the permanent tooth beneath the impacted primary tooth. In this case report, we present the treatment of a 14-year-old female patient who presented with a chief complaint of missing teeth in the lower left back jaw region. OPG finding reveal the exceptional occurrence of simultaneous impact ion involving the primary second molar and its succedaneous teeth- a remarkable rare observation. Based on the CBCT findings, it was revealed that the impacted premolar had ruptured the lower border of the mandible. To address this issue, a comprehensive treatment plan was developed. The treatment plan included the use of a bonded appliance to create space for tooth eruption, followed by surgical removal of the primary molar to provide more room for the impacted premolar. A traction chain was then attached from a fixed orthodontic appliance to the impacted premolar, guiding it into the correct position. Throughout the treatment process, the patient was closely monitored for any signs of discomfort or complications, and necessary adjustments were made to ensure the best possible outcome. The combination of these techniques proved to be effective in achieving successful orthodontic treatment and improved dental health for the patient.
