Rescue therapy with orthodontic traction to manage severely impacted mandibular second molars and to restore an alveolar bone defect.

This case report describes the successful treatment of severely impacted mandibular second molars with severe apical root resorption of the mandibular first molars. The vertically impacted second molars were orthodontically moved (using orthodontic mini-implants) without additional root resorption of the first molars. The orthodontic treatment provided a satisfactory and stable outcome by improving the periodontium surrounding the first and second molars. The treatment also eliminated the need for prosthetic treatment by preserving the first and second molars.
