Retrospective data from sinus floor augmentation bone grafts were collected from 38 surgeons for 1007 sinus grafts that involved the placement of 2997 implants over a 10-year period, with the majority of the implants followed for 3 years or more postrestoration. There were 229 implant failures reported. Various root-form implants and grafting modalities were used. A consensus conference was organized to evaluate the data and reach a consensus on optimal treatment protocols. The complete database demonstrated a 90.0% success rate for implants placed in sinus grafts with at least 3 years of function. Differences in grafting materials, implant surfaces, and timing protocols were statistically analyzed. However, the database was so multivariate and multifactorial that it was difficult to draw definitive conclusions; these must await controlled prospective studies. The consensus conference therefore developed and voted on multiple consensus statements derived by committee review for bone graft materials, type of implants, timing for implant placement, failure analysis, radiographic analysis, indications/contraindications, prosthetics, and nomenclature. Several consensus statements were obtained, the most significant being that the sinus graft should now be considered a highly predictable and effective therapeutic modality.
收集了38位外科医生关于鼻窦底增高骨移植的回顾性数据，涉及1007例鼻窦移植，在10年期间植入了2997颗种植体，大多数种植体在修复后随访3年或更长时间。报告了229例种植体失败。使用了各种根形种植体和移植方式。组织了一次共识会议来评估数据，并就最佳治疗方案达成共识。完整的数据库显示，植入鼻窦移植且至少有3年功能的种植体成功率为90.0%。对移植材料、种植体表面和时间方案的差异进行了统计分析。然而，该数据库具有如此多的变量和因素，以至于很难得出明确的结论；这些结论必须等待对照前瞻性研究。因此，共识会议针对骨移植材料、种植体类型、种植体植入时间、失败分析、影像学分析、适应证/禁忌证、修复学和命名法等方面，制定了由委员会审查得出的多项共识声明并进行投票。获得了几项共识声明，其中最重要的是，现在应将鼻窦移植视为一种高度可预测且有效的治疗方式。
