Abstract: 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 tis-sue 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.
