摘要
目的观察两方向法经嵴顶提升倾斜型上颌窦底的临床效果。方法对6例拟行上颌后牙区种植修复的病例,用两方向法经嵴顶提升倾斜型上颌窦底。1个种植位点从2个方向进行经嵴顶提升,先行非植入方向骨凿冲顶窦底提升,将较低处黏膜提起,再行常规的植入方向骨凿冲顶窦底提升和种植体植入手术。结果术后拍摄锥形束CT证实6例患者均获得了良好的上颌窦底提升效果,种植体与邻牙位置关系适当,种植体尖端有黏膜覆盖,术后鼻腔无血性分泌物,无明显疼痛,术后6个月内无种植体脱落。结论对倾斜型上颌窦底可以考虑使用两方向法经嵴顶提升上颌窦底。
Objective To observe the clinical effect of two-direction inclined maxillary sinus floor augmentation from alveolar crest. Methods Sinus floor were augmented on the same site from two directions with the transalveolar technique. Firstly, lower sinus floor were augmented from the non-implant direction. Secondly, sinus floor were augmented with simultaneous placement of dental implants from the presupposed implant direction. Results Postoperative cone beam computerized tomography（ CBCT） proved good effects of sinus floor augmentation, with satisfactory positional relationship with the adjacent teeth. The implant tips were covered by mucous, with no nasal hemorrhagic secretions and no obvious pain. No implant fell off within 6 months after surgery. Conclusion Two-direction maxillary sinus floor augmentation from alveolar crest is a possible choice to augment inclined maxillary sinus floor.
