摘要/Abstract

摘要： 目的探究帐篷螺钉技术在治疗严重骨缺损中的临床效果。方法收集2021年1月至2023年12月期间就诊的11例严重骨缺损患者、共计19个骨增量位点的病例资料。应用帐篷螺钉技术进行骨增量,术后6个月植入种植体,观察骨增量效果及并发症情况。结果术后骨宽度平均增加（3.12±0.30）mm,骨高度平均增加（1.29±0.50）mm。4个骨增量位点（2例患者）发生帐篷螺钉暴露,但骨增量区域无感染迹象。结论帐篷螺钉技术符合“中央支撑”理念,即在骨增量区域中央放置帐篷螺钉,使其贯穿并支撑成骨空间。该方法有效增加了水平骨宽度,但对垂直骨增量效果尚存争议,仍需进一步研究。

Abstract: Objective To investigate the clinical efficacy of the tenting screw technique in the treatment of severe bone defects. Methods A total of 11 patients with severe bone defects, involving 19 graft sites, were included between January 2021 to December 2023. The tenting screw technique was used for bone augmentation, and dental implants were placed 6 months after the procedure. Bone augmentation outcomes and complications were recorded and evaluated. Results The average horizontal bone width increased by (3.12±0.30) mm, while the average vertical bone height increased by (1.29±0.50) mm. Exposure of tenting screws occurred at 4 grafted sites (in 2 patients), but no signs of infection were observed in the grafted areas. Conclusion The tenting screw technique aligns with the “central support” concept, wherein a tenting screw is positioned centrally within the defect to provide support and maintain the osteogenic space. This method effectively enhances horizontal bone width, though its efficacy in vertical bone augmentation remains controversial and requires further investigation.
