上颌窦内外提升植骨术在口腔种植中的临床应用

Clinical application of maxillary sinus lift accompanied bone graft in oral implantation

目的采用上颌窦内外提升植骨术扩大种植适应证,并观察其修复使用的成功率。方法通过40例患者55颗上颌窦内外提升植骨术及同期ITI及BLB种植体植入术,术后1、3、6个月检查评测种植体骨结合状况、上颌窦愈合以及戴牙修复后12、3、年的使用情况。结果 54颗种植体无松动、脱落及上颌窦炎症发生,X线检查种植体与骨均形成良好骨结合,术后6个月完成义齿修复。经6-54个月随访观察,临床效果良好,1颗因咬硬物失败。结论掌握适应证和手术技巧,上颌窦内外提升植骨术并同期种植植入术能有效地扩大种植适应证,解决了上颌后牙骨高度不足的问题。

Objective To observe effects of two kinds of sinus lifting techniques with simultaneous implant placement to expand the indications of oral implant.Methods 55 implant denture in 40 patients＇ which was implanted by using ITI and BLB implant surgery,at the same time,and two kinds of sinus lifting techniques with simultaneous implant placement were used to evaluate the condition of the osseointegration one month,three months and six months later after surgery,and the heal of the maxillary sinus and the service conditions were assessed one,two,three years after prosthesis.Results 54 implants didn＇t become flexible,drop off and maxillary sinusitis,X-ray illustrated the bone and the implant formed good osseointegration.The artificial denture was performed six months after the implant operation.Both had excellent clinical effect during 6-54 months followed-up,one implant failed because of biting hard food.Conclusion After grasping the indications and the operation skills,maxillary sinus lifting,bone graft,and simultaneous placement of implant surgery can effectively expand the indications of implantology and resolve the question that some patients are lack of bone quantity in distomolar＇s area.
