Bicon植体联合上颌窦内提升术用于上后牙种植

Application of Bicon Implant and Maxillary Sinus Inner Lift Technology for Upper Posterior Missed Teeth

目的:探讨Bicon植体联合上颌窦内提升术用于上后牙种植区骨量不足的临床疗效。方法:对已完成种植修复的13例20颗上颌后牙Bicon植体修复效果进行回顾性研究,通过临床检查和CBCT评估Bicon种植体在骨量不足情况下,通过上颌窦内提升技术,统计种植修复成功率。结果:20颗Bicon植体,上颌窦内提升高度2~5mm,临床检查初期稳定性良好,未见上颌窦黏膜穿孔,术后4个月骨整合良好,修复体负载1~2年后检查植体无动度,CBCT显示种植体周围无明显骨吸收,种植体留存率100%。结论:Bicon植体联合上颌窦内提升术可成功用于上后牙区骨量不足的种植修复。

Objective：To evaluate the clinical effect of Bicon implant combined with maxillary sinus inner lift technology for upper posterior missed teeth.Methods：Retrospectively study was used to check the prosthetic effect of 20 Bicon implants in 13 patients.Clinical examination and CBCT were taken to learn the successful rate of Bicon implants under the condition of lack of bone mass.Results：All 20 Bicon implants were steady with 2-5mm sinus inner lift and no maxillary sinus mucosa perforation was happened under clinical examination.CBCT showed that bones around all implants were not absorbed.Conclusion：Bicon implant combined with maxillary sinus inner lift technology can successfully restore upper posterior missed teeth with bone defect.
