摘要
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;RBH<4 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RBH<4 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。
Objective 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.Methods 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.Results 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 RBH<4 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.Conclusion When RBH in the maxillary posterior tooth area was<4 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.
