The survival of implants placed in the resorbed maxillae was investigated. Both edentulous and partially edentulous patients were evaluated including those who underwent 'sinus lift' procedures. The group of patients with a sinus floor augmentation showed a five-year cumulative survival rate varying between 100% for fixed bridges on implants in the partially edentulous maxillae and 75.6% for implants under overdentures placed in severely resorbed edentulous maxillae. It is concluded that placement of implants in the augmented sinus-floor is justified, if the patient is well informed. The procedure can provide a good solution for the prosthetic problems of patients with a resorbed maxilla.
研究了植入吸收性上颌骨中的种植体的存活率。对无牙颌和部分无牙颌患者进行了评估，包括那些接受过“上颌窦提升”手术的患者。上颌窦底增高组的五年累积存活率有所不同，部分无牙颌上颌骨中种植体固定桥的五年累积存活率为100%，而严重吸收性无牙颌上颌骨中覆盖义齿下种植体的五年累积存活率为75.6%。得出的结论是，如果患者充分知情，在增高的上颌窦底植入种植体是合理的。该手术可为上颌骨吸收患者的修复问题提供一个良好的解决方案。
