摘要： 本文报告1例28岁女性患者,因左上颌乳牙滞留伴25腭侧异位就诊。影像学检查显示双侧上颌窦显著气化,左侧上颌窦底骨高度仅约1.45 mm。采用自体牙骨粉（autogenous tooth bone graft,ATBG）并行上颌窦外提升术以重建25区骨量。术后2.5个月CBCT显示该区牙槽骨高度显著增加至约15.99 mm。继而采用分段式隐形矫治技术：一期牵引25牙旋转并直立入弓,二期精细调整。术后2年CBCT显示植骨区维持骨高度约14.39 mm,骨宽度超过9 mm,新生骨整合良好,可支持正常咬合功能。

Abstract: This case report described a 28-year-old female who presented with a retained maxillary deciduous tooth and palatally displaced permanent tooth 25. Cone-beam CT revealed extensive pneumatization of both maxillary sinuses, with the residual bone height at the left sinus floor measuring only 1.45 mm. To augment the deficient alveolar bone, autogenous tooth bone graft (ATBG) was prepared chairside and used to perform a lateral sinus floor elevation at the site of tooth 25. At 2.5 months postoperatively, CBCT demonstrated a significant increase in vertical bone height to approximately 15.99 mm. Subsequently, staged invisible orthodontic treatment was adopted: in the first stage, tooth 25 was tractioned to rotate and be upright into the dental arch; in the second stage, fine adjustment was conducted. CBCT examination at 2 years postoperatively demonstrated that the bone height in the bone-grafted area was maintained at approximately 14.39 mm, the bone width exceeded 9 mm, the newly formed bone showed good integration, and it could support normal masticatory function.
