Reconstruction of the totally edentulous patient with dental implants has become routine treatment with predictable outcomes. Firm keratinized tissue surrounding the implants and adequate vestibular depth are among the determining factors for long-term implant success. In the staged approach of mandibular implant reconstruction, adequate vestibular depth and attached gingiva surrounding the implants can be readily established at the time of implant placement or when the implants are uncovered. However, when extractions and necessary mandibular ridge reduction to create adequate width are performed immediately before implant placement, maintaining adequate keratinized tissue around the implants and preventing prolapse of the vestibule can present a challenging situation. This report presents a technique that allows the surgeon to stabilize vestibular depth and at the same time position the flaps around the implants and preserve the attached gingiva.
使用牙种植体对全口无牙患者进行重建已成为具有可预测结果的常规治疗方法。种植体周围坚韧的角化组织和足够的前庭深度是种植体长期成功的决定性因素。在下颌种植体重建的分期方法中，在种植体植入时或种植体暴露时，可以很容易地建立种植体周围足够的前庭深度和附着龈。然而，当在种植体植入前立即进行拔牙和必要的下颌牙槽嵴减容以创造足够宽度时，在种植体周围维持足够的角化组织并防止前庭脱垂可能是一个具有挑战性的情况。本报告介绍了一种技术，该技术可使外科医生稳定前庭深度，同时将种植体周围的瓣定位并保留附着龈。
