This report presents the case of a 20-year-old female patient exhibiting an infraoccluded ankylosed maxillary central incisor that was avulsed and replanted after traumatic injury during childhood. To reposition the osseous and gingival margins of the ankylosed tooth to an ideal level, a new alveolar distraction device that uses anchoring miniscrews with a single tooth dento-osseous osteotomy was fabricated and the ankylosed tooth was successfully treated with exceptional patient compliance.
本报告介绍了一例 20 岁女性患者的病例，该患者幼年时因外伤导致上颌中切牙埋伏阻生并脱位，随后进行了再植。为了将埋伏牙的骨和龈缘重新定位到理想的位置，我们制作了一种新型牙槽骨牵张器，该牵张器使用带有单牙牙-骨切开术的锚固微型螺钉，同时患者具有极佳的配合度，最终成功治疗了该埋伏牙。
