When tooth ankylosis occurs in growing children, the ankylosed tooth fails to erupt and gradually positions itself below the occlusal plane. This causes functional and esthetic problems, and orthodontic treatment is often impossible. To clarify this problem, we developed a new treatment protocol for the movement of ankylosed teeth. This consists of single-tooth dento-osseous osteotomy and alveolar bone distraction using orthodontic multibracket appliances. A special distraction device is not required, thus reducing the burden to patients. Two cases in which an ankylosed maxillary central incisor was successfully treated with this protocol are presented.
当正在生长发育的儿童出现牙齿粘连时，粘连的牙齿无法萌出，并逐渐移位至咬合平面以下。这会导致功能和美观问题，并且正畸治疗通常无法进行。为了阐明这一问题，我们开发了一种用于粘连牙齿移动的新治疗方案。该方案包括单颗牙齿的牙骨切开术以及使用正畸多托槽矫治器进行牙槽骨牵张成骨。无需特殊的牵张装置，从而减轻了患者的负担。本文介绍了两例采用该方案成功治疗上颌中切牙粘连的病例。
