Abstract
- We present two cases of severe eruption disturbances of the mandibular right second molars treated with orthodontic traction using miniscrews placed in the mandibular ramus region. In both cases, anatomical limitations were assessed in advance using cone beam computed tomography. The miniscrews provided stable anchorage, allowing effective occlusal access and proper uprighting of the tooth axis. After approximately 6 – 11 months of traction, the mandibular second molars successfully erupted into their normal occlusal positions without complications, such as root resorption or periodontal damage. These cases suggest that orthodontic traction using ramus miniscrews may be an effective treatment option for managing eruption disturbances in mandibular second molars with complex anatomical conditions.
