Objective: To demonstrate how aligners were used to manage a displaced root of a mandibular canine in a male adult patient.
Materials and methods: A 24-year-old man experienced relapse after a previous orthodontic treatment. He presented to a private dental clinic with a mandibular left canine root that was almost out of the bone. The present authors explained to the patient that they would like to attempt an innovative form of treatment with clear aligners to manage the movement of the root, and requested that a CBCT scan be taken.
Results: The treatment goal was achieved and the canine root was restored back into the alveolar bone after 11 months of therapy.
Conclusion: Root displacement can be managed with clear aligner therapy.
