This study evaluated the use of bone ring technique with xenogeneic bone grafts in treating horizontal alveolar bone defects. In total, 11 patients in need of horizontal bone augmentation treatment before implant placement were included in this retrospective study. All patients received simultaneous bone augmentation surgery and implant placement with xenogeneic bone ring grafts. We evaluated the postoperative efficacy of the bone ring technique with xenogeneic bone grafts using radiographical and clinical parameters. Survival rates of implants were 100%. Cone-beam computed tomography revealed that the xenogeneic bone ring graft had significantly sufficient horizontal bone augmentation below the implant neck platform to 0 mm, 1 mm, 2 mm, and 3 mm. It could also provide an excellent peri-implant tissue condition during the 1-year follow-up after loading. The bone ring technique with xenogeneic bone ring graft could increase and maintain horizontal bone mass in the region of the implant neck platforms in serious horizontal bone defects.
本研究评估了使用异种骨环技术治疗水平牙槽骨缺损。共有 11 名需要在种植体植入前进行水平骨增量治疗的患者被纳入本回顾性研究。所有患者均接受了同期骨增量手术和异种骨环移植物植入。我们使用影像学和临床参数评估了异种骨环移植物的骨环技术的术后疗效。种植体的存活率为 100%。锥形束 CT 显示，异种骨环移植物在种植体颈平台下 0mm、1mm、2mm 和 3mm 处具有显著充足的水平骨增量。在负荷后 1 年的随访期间，它还可以提供良好的种植体周围组织状况。异种骨环移植物的骨环技术可增加和维持严重水平骨缺损部位的种植体颈平台区域的水平骨量。
