2、結(jié)果：術(shù)中無1例上頜竇黏膜破裂，術(shù)后局部傷口疼痛和頭痛等2例，鼻腔出血1例，有3枚種植體在骨整合期脫落，脫落5個月后均重新種植成功，12顆種植體平均上頜竇底提升高度為7．36mm(5．4～11．2mm)，植骨術(shù)后6個月上頜竇底形態(tài)均會有明顯的骨改建，成骨效果良好。結(jié)論：與開窗式上頜竇外提升相比，上頜竇底內(nèi)提升植骨手術(shù)創(chuàng)傷小，成骨快，可有效解決上頜后部牙槽骨高度嚴重不足的牙種植問題。[關(guān)鍵詞]上頜竇底內(nèi)提升；牙種植；可吸收珊瑚羥基磷灰石[中圖分類號]R782．12[文獻標(biāo)志碼]A[文章編號]1008-6455(2O15)11-0038-04Applicationofcorallinehydrox
