2、结果：术中无1例上颌窦黏膜破裂，术后局部伤口疼痛和头痛等2例，鼻腔出血1例，有3枚种植体在骨整合期脱落，脱落5个月后均重新种植成功，12颗种植体平均上颌窦底提升高度为7．36mm(5．4～11．2mm)，植骨术后6个月上颌窦底形态均会有明显的骨改建，成骨效果良好。结论：与开窗式上颌窦外提升相比，上颌窦底内提升植骨手术创伤小，成骨快，可有效解决上颌后部牙槽骨高度严重不足的牙种植问题。[关键词]上颌窦底内提升；牙种植；可吸收珊瑚羟基磷灰石[中图分类号]R782．12[文献标志码]A[文章编号]1008-6455(2O15)11-0038-04Applicationofcorallinehydrox
