This case report refers to an 11-year-old boy with avulsion of the upper left central and lateral incisors. The teeth were replanted after 4 h, splinted with a semi-rigid splint for 12 days, and then endodontically treated. Severe progressive root resorption was seen after 2 years and the teeth were extracted. The boy had a normal occlusion with spacing in both jaws and slight protrusion of the anterior teeth. The treatment objectives were to close some of the spaces by mesial movement of the buccal segments in the upper jaw to minimize bone loss for a future single osseointegrated implant. Fixed appliance in combination with a removable plate was used for the mesial movements, levelling, and alignment of the upper jaw. Fixed appliance in the lower jaw and Class II traction were used for the final adjustment of the occlusion. A good occlusion with coincident upper and lower midlines and up-righted anterior teeth were achieved. A Maryland bridge was performed as a temporary solution for a future osseointegrated implant.
本病例报告涉及一名11岁男孩，其左上中切牙和侧切牙发生牙脱位。牙齿在4小时后再植，用半刚性夹板固定12天，然后进行根管治疗。2年后出现严重的进行性牙根吸收，牙齿被拔除。该男孩咬合正常，上下颌均有间隙，前牙轻度前突。治疗目标是通过上颌颊侧段近中移动关闭部分间隙，以尽量减少未来单颗骨整合种植体的骨量丢失。使用固定矫治器结合可摘板进行上颌的近中移动、整平与排齐。下颌使用固定矫治器并进行II类牵引以最终调整咬合。实现了良好的咬合，上下中线对齐，前牙直立。作为未来骨整合种植体的临时解决方案，进行了马里兰桥修复。
