摘要
目的:观察自体牙作为骨移植材料在上颌窦外提升术中应用的临床效果。方法:男性患者1例,将拔除的下颌智齿制成牙本质颗粒,混合自体富血小板纤维蛋白(Platelet Rich Fibrin,PRF)植入开窗提升后的左侧上颌窦,同期完成种植体植入。随访1年,观察骨再生和临床修复效果。结果:术后反应轻微。X线片示植骨区有新骨生成,牙本质颗粒逐渐吸收,植体稳固,修复效果满意。结论:自体牙制成的骨移植材料,可以用来重建种植区的骨缺损,效果良好,值得推广。
Objective： To evaluate the clinical effects of autologous tooth as bone graft material in maxillary sinus lateral lift. Methods： The removed the wisdom teeth from one male patient were used to produce the dentin granules and mixed with autologous PRF. The materials were put into the left maxillary sinus after the membrane elevation. One implant was placed immediately following the bone grafting. The patient was followed-up for 1 year to observe the bone regeneration effects and clinical outcome. Results：The postoperative reactions were mild. X-ray investigation demonstrated new bone formation at the bone grafting site. The dentine granules were gradually absorbed. The implant of placed at the grafting site was stable and patient was satisfied with the restoration function. Conclusion： Autologous tooth as bone grafting material is a feasible way to reconstruct bone defects around implant. It is an effective technique worth promoting.
