骨扩张技术在老年种植患者骨宽度不足中的应用

Application of Bone Expansion Technique in the Elderly Patients with Deficiency of Alveolar Bone Width

目的:评价牙槽骨扩张技术在老年种植患者骨宽度不足中的应用效果。方法:15例牙槽骨宽度不足的老年牙缺失患者,术前CBCT检查牙槽骨宽度为3.0～5.0 mm,采用骨扩张术同期植入35枚种植体,术后即刻CBCT观察种植体植入情况,随访1周,观察伤口愈合情况,术后6个月复查CBCT观察种植体骨结合情况。结果:术中患者无不适感,术后无明显不良反应发生。骨扩张术后牙槽骨宽度平均值为6.5 mm,6个月后行二期手术时骨宽度平均值为5.9 mm,较术前宽度平均增加2.2 mm。结论:骨扩张技术损伤小、较为微创,适用于老年骨宽度不足患者的种植手术。

Objective: To evaluate the effect of alveolar bone expansion technique in elderly patients with the deficiency of alveolar bone width. Methods: 15 elderly patients of teeth loss with the deficiency of alveolar bone width were chosen. Preoperative CBCT showed that the widths of the alveolar bone were 3.0-5.0 mm. Applying bone expansion technique,35 implants were instantly embedded. The implants case was observed immediately after surgery. Follow-up for 1 week after operation was applied to observe the wound healing. CBCT was reexamined 6 months after surgery to observe the osseointegration of implants. Results: The patients had no discomfort during the operation and no obvious adverse reactions after the operation. The average width of alveolar bone after bone expansion was 6.5 mm. The average bone width at the second stage of surgery 6 months later was 5.9 mm, an average increase of 2.2 mm compared with the preoperative width. Conclusion: Compared with traditional surgical methods, bone expansion technology has less damage to patient and is minimal invasive.It’s suitable for the elderly patients with deficient alveolar bone.
