Title: Extrusion of severely impacted mandibular first molar using partial orthodontics and temporary anchorage miniscrews
Abstract: Background This study reports a case in which a severely impacted lower first molar was recovered with a combined orthodontic therapy and minimally invasive oral surgery with special focus to patientís aesthetic demands.
Case report A 12-year-old female patient was complaining delayed eruption of mandibular right first molar. Radiographic exam showed a severe tooth impaction with a close relationship between tooth roots and mandibular nerve. As the patient refused full arches orthodontic treatment, a partial orthodontic approach was projected. During treatment, temporary miniscrews were placed in both upper and lower arches, in order to allow dental movement with maximum anchorage. After a 24 month-therapy the tooth was extruded, so the appliance and the miniscrews were removed.
Conclusion The present case shows that severe tooth impaction can be resolved with a combined partial orthodontic- minimally invasive surgical treatment.
