BACKGROUND: The incidence of mandibular first molar impaction is less than 0.01%, and there are no standard treatment guidelines. Orthodontic traction can be chosen as a treatment plan in some circumstances. One miniscrew in the mandibular ramus can offer sufficient anchorage for the traction of impacted mandibular molars.
CASE DESCRIPTION: A 10-year-old boy had a completely labially positioned maxillary left canine and a deeply impacted mandibular left first molar associated with a dentigerous cyst. Using 2 palatal miniscrews for distalization, space was created to align the maxillary left canine. In addition, a miniscrew in the mandibular ramus facilitated the traction of the mandibular left first molar. After 3 years and 6 months of orthodontic treatment, the integrity of the dental arch was restored, and occlusal function was reestablished.
PRACTICAL IMPLICATIONS: A ramus miniscrew is an effective and viable treatment option for the orthodontic traction of deeply impacted mandibular molars.
