上颌侧切牙根折致唇侧组织缺损的即刻种植与即刻修复病例

Immediate implant placement of the compromised site in aesthetic zone-a case report

目的:观察美学区牙根折裂伴有唇侧骨壁缺损,牙龈明显退缩的患牙,采用拔牙同期进行微创骨增量后,做即刻种植并即刻修复的临床效果。方法:不翻瓣微创拔患牙,采用骨膨胀技术制备种植床,植入种植体后做螺丝固位临时冠修复,术后7个月完成烤瓷冠永久修复。结果:种植体周软组织状况逐步改善,最终龈缘高度恢复到与对侧同名自然牙一致,定期复查25个月,种植体周围软硬组织健康稳定,美学效果超出预期。结论:该案例采用微创骨增量解决了唇侧骨缺损,是获得治疗成功的基础。

Objectives： To observe the clinical results of tooth root fracture in the aesthetic area accompanied with the defect of the labial bone and the gingival recession by minimally invasive bone augmentation,immediate implant and immediate repair after tooth extraction. Methods： Minimal-invasive and flapless method were used for tooth extraction, the bone expansion technique was used to prepare implant bed,temporary crown was used to restore the occlusion, the restoration was completed by permanent crown 7 months later. Results： The status of peri-implant soft tissue was improved gradually, the gingival margin recovered to the same level as that of the contralateral natural tooth after 25 months. The soft and hard tissue surrounding the implant was healthy and stable, and the aesthetic result exceeded expectations. Conclusion： In this case, we figure out the labial defect could be successfully treated by using the minimally invasive bone augmentation.
