The reconstruction of the severe atrophy of the maxilla using dental implants requires extensive surgical treatments. Sinus lift procedure, ridge augmentation with free bone grafts or free vascularized bone transfers represent the common techniques. With regard to a higher life expectancy the number of patients suffering from limited chewing function based on atrophic bone conditions will increase. In addition to a higher number of failed implants in elderly people ask for other treatment strategies to regain proper oral function with limited surgical effort. This case report presents the failed treatment of maxilla, using disc implants and shows the new maxillary reconstruction using Brånemark-Zygoma implants combined with standard Nobel Replace implants in order to avoid extensive augmentation procedure.
使用牙种植体修复严重萎缩的上颌骨需要进行广泛的外科治疗。上颌窦提升术、游离骨移植或游离带血管骨移植进行牙槽嵴增高术是常用的技术。随着预期寿命的提高，因骨萎缩状况导致咀嚼功能受限的患者数量将会增加。此外，老年人中种植体失败的数量较多，这就需要采取其他治疗策略，以在有限的手术操作下恢复正常的口腔功能。本病例报告展示了使用盘状种植体修复上颌骨的失败治疗，并介绍了使用Brånemark-Zygoma种植体联合标准的Nobel Replace种植体进行上颌骨重建的新方法，以避免进行广泛的骨增量手术。
