摘要

背景：由于牙槽嵴与上颌窦底之间缺乏足够的骨，在上颌后区常规种植通常是困难的。然而，骨高度的不足可以通过上颌窦底部的窦提升手术来克服，这是使用各种类型的骨移植物来完成的。目的：本研究的目的是评估使用钛管制备的富含血小板纤维蛋白（T-PRF）作为填充物代替骨移植物的单期外侧窗口外窦提升种植体的骨增重、成功和稳定性。材料与方法：研究对象为6例单侧或双侧上颌后缺失患者，年龄30 ~ 60岁，经侧窗上颌窦提升术7例。使用钛管制备的富血小板纤维蛋白（T-PRF）一期同时放置14个种植体。牙槽骨嵴与窦底之间的残余骨高度（RBH）为4 ~ 5mm。所有患者术前、术后立即和6个月后均行CBCT成像，评估骨增重和密度，种植体稳定商（ISQ）在3个月和6个月后立即评估。结果：术后即刻ISQ平均值为67.50，术后3个月平均值为72.14，术后6个月平均值为76.14，各监测期差异均有统计学意义。鼻窦提升前的平均残余骨高度（RBH）为4.53 mm，鼻窦提升及种植后6个月的平均骨高度为12.07 mm，平均骨增高为7.54 mm。术后6个月获得骨的平均骨密度为+479.29 Hu。结论：在本研究的局限性内，单独使用钛管制备的富血小板纤维蛋白（T-PRF）作为单独的填充物，可以有效地一次完成外窦提升和种植体放置。

The use of platelet-rich fibrin prepared with titanium tubes (T-PRF) in external maxillary sinus lift combined with simultaneous implant placement (case series)

Background

Conventional implantation in the posterior maxillary region is often difficult due to the lack of sufficient bone between the alveolar crest and the floor of the maxillary sinus. However, the lack of bone height can be overcome by grafting the floor of the maxillary sinus with a sinus lift procedure, which is performed using various types of bone grafts.

Aim

The aim of this study was to evaluate the bone gain, success and stability of implants associated with a single-stage lateral window external sinus lift using platelet- rich fibrin prepared with titanium tube (T-PRF) alone as a filler instead of bone grafts.

Materials and methods

The study sample consisted of 7 case series of maxillary sinus lift via the lateral window in 6 patients with unilateral or bilateral posterior maxillary loss, aged 30–60 years. 14 implants were placed in one stage simultaneously with sinus lift using platelet-rich fibrin prepared with titanium tubes (T-PRF). The residual bone height (RBH) between the alveolar bone crest and the sinus floor was 4–5 mm.

All patients underwent CBCT imaging preoperatively, immediately postoperatively, and 6 months later to assess the amount of bone gain and density, Implant Stability Quotient (ISQ) was evaluated immediately and after 3 and 6 months.

Results

The mean of ISQ values immediately after implantation was 67.50, after 3 months was 72.14, and after 6 months was 76.14, with a statistically significant difference between the monitoring periods. The mean of residual bone height (RBH) before the sinus lift was 4.53 mm, the mean of bone height 6 months after the sinus lift and implantation was 12.07 mm, and the mean of bone gain height was 7.54 mm. The mean bone density of gained bone 6 months after surgery was +479.29 Hu.

Conclusion

Within the limitations of this study, the use of platelet-rich fibrin prepared with titanium tubes (T-PRF) alone as a solo filler is effective in performing external sinus lift and implant placement in one stage.
