To explore the changes in bone height of the maxillary sinus floor at different sinus ridge heights after transcrestal sinus floor elevation (tSFE) with the simultaneous implantation of short implants.A total of 74 Bicon short implants were implanted into 37 patients during the same period of maxillary sinus elevation. The residual bone height (RBH)4 mm group has 43 sites, and the RBH≥4 mm group has 31 sites. After 5 years of follow-up observation, the implant survival rate and the change in bone height achieved in the maxillary sinus over time were measured and analyzed via clinical examination and X-ray imaging.In the 74 implantation sites, the elevation height of the sinus floor was (6.64±1.32) mm and the bone height of the sinus floor was (3.35±1.29) mm 5 years after loading. No statistical difference was observed in the bone resorption of the implant neck between the RBH4 mm and RBH≥4 mm groups. Meanwhile, a statistical difference was noted in the bone height obtained in the maxillary sinus between the two groups.When RBH in the maxillary posterior tooth area was4 mm, the simultaneous implantation of Bicon short implants with tSFE can achieve a high implant survival rate and bone gain in the maxillary sinus, but does not increase the absorption of the alveolar ridge bone.目的 研究上颌后牙区不同窦嵴距时，采用经牙槽嵴顶上颌窦底提升植骨并同期植入短种植体术后，种植体周围骨高度随时间的变化情况。方法 对37例患者进行经牙槽嵴顶上颌窦底提升植骨并同期植入共74枚Bicon短种植体，其中剩余牙槽骨高度（RBH）4 mm组43个位点，RBH≥4 mm组31个位点。随访5年后，通过临床检查和X线片测量分析不同窦嵴距时，种植体周围骨高度随时间的变化情况。结果 74个种植位点术后窦底提升高度（6.64±1.32）mm，修复负载5年后上颌窦内获得骨高度为（3.35±1.29）mm；RBH4 mm组和RBH≥4 mm组之间的种植体颈部骨吸收量的差异无统计学意义，而上颌窦内获得骨高度及种植体顶部骨高度的差异有统计学意义。结论 上颌后牙区RBH4 mm时，采用经牙槽嵴顶上颌窦底提升同期植入Bicon短种植体的术式可获得较高的种植体存留率及上颌窦内骨增加量，同时并不会增加牙槽嵴顶骨吸收量。. |
