在 12 年期间（1984-1996），118 个上颌嵌体自体骨移植物和 248 个商业纯钛螺纹根形骨内种植体被植入 54 名连续接受治疗的上颌骨受损患者体内。在这项回顾性临床研究中，对 3 组患者进行了回顾，组的选择是基于解剖位置和手术进入受区的情况。第 1 组包括通过口内造口暴露将骨移植物放置在窦底的患者，第 2 组包括通过前口内鼻切开暴露将骨移植物放置在鼻底的患者，第 3 组包括通过口内 Le Fort I 截骨术下骨折暴露将骨移植物放置在鼻窦和鼻底的患者。每位患者都接受了种植体支持的假牙。对于 3 组合并而言，骨内种植体的存活率为 87%，自体骨移植的存活率为 100%。 3组的假牙成功率为95%。 69 个假牙的平均使用寿命为 57.1 个月，而 3 个假牙因种植体丢失而需要重制。在本研究列出的医疗和机械风险因素中，当前使用尼古丁、鼻窦炎病史、磨牙部位种植体植入和较短的种植体长度对种植体失败的影响最大。
During a 12-year period (1984-1996), 118 maxillary inlay autogenous bone grafts and 248 commercially pure titanium threaded root-form endosseous implants were placed in 54 consecutively treated patients with compromised maxillary bone. In this retrospective clinical study, 3 groups of patients were reviewed, group selection being based on anatomic location and surgical access to the recipient site. Group 1 included patients with bone grafts placed in the antrum floor via an intraoral antrostomy exposure, group 2 included patients with bone grafts placed in the nasal floor via an anterior intraoral nasotomy exposure, and group 3 included patients with bone grafts placed in the antral and nasal floor via an intraoral Le Fort I osteotomy downfracture exposure. Each patient received an implant-supported dental prosthesis. For the combined 3 groups, survival rates were 87% for endosseous implants and 100% for autogenous bone grafts. The success rate for the dental prostheses in the 3 groups was 95%. Sixty-nine dental prostheses functioned a mean of 57.1 months, whereas 3 prostheses required remaking because of implant loss. Of the medical and mechanical risk factors tabulated in this study, current use of nicotine, history of sinusitis, molar site implant placement, and shorter implant lengths had the most influence on implant failure.
