· Female, 49 yo. 患者 女性，49 岁
· Missing bilateral upper molars for many years, It was found on the exam that there was a marked pneumatization of maxillary sinuses, only 2-3 mm bone height under the sinus floors, impossible for implant placement unless more bone regenerated by sinus lift procedure. 双侧上颌磨牙缺失多年， 术前检查发现双侧上颌窦低垂， 植牙区只有2-3毫米高度的牙槽骨, 除非用上颌窦提升植骨， 否则无法种植牙。
· Staged sinus lift procedures were performed on both left and right sides, after 4 months, two implants were placed, another 4 month later, two implant supported crowns were installed. 首先进行分阶段的双侧上颌窦提升植骨， 4 个月确定植骨成功后 将两颗种植 体植入， 再过4个月后， 安装了种植牙冠。
Before the bilateral sinus lift, the X-ray showed very limited bone height (
