不同植骨材料在上颌窦开窗提升植骨同期种植体植入术的初期临床效果评价

Evaluation of preliminary clinical results of different sinus graft materials for the sinus augmentation technique and simultaneously placement of implants

目的对不同植骨材料在上颌窦开窗提升植骨同期种植体植入术的初期临床效果进行评价。方法根据上颌窦植骨材料的不同分为3组:β-磷酸三钙(β-TCP)组;同种异体冻干骨组;β-TCP+同种异体冻干骨组。分别评估各组术后临床情况、修复时移植骨垂直高度保留率、修复时的种植体的稳定系数,并加以比较。结果 3组初期临床效果良好,无失败病例。β-TCP组垂直骨高度保留率(58.82±8.17)%,种植体的稳定系数75.36±3.72。同种异体冻干骨组垂直骨高度保留率(61.81±10.26)%,种植体的稳定系数78.20±3.77。β-TCP+同种异体冻干骨组垂直骨高度保留率(60.56±7.06)%,种植体的稳定系数75.06±4.20。各组数据无统计学差异。结论 3种不同植骨材料在上颌窦开窗植骨同期种植体植入术中均具有良好初期临床效果。

Objective To evaluate preliminary clinical results of different sinus graft materials for the sinus augmentation technique and simultaneously placement of implants.Methods According to the sinus bone graft materials,three groups were divided： group β-TCP;group freeze-dried human bone;group β-TCP＋ freeze-dried human bone.Evaluate each group′s clinical results,vertical height of bone graft retention,and ISQ.Results Good clinical results of three groups were got without failure.Group（β-TCP）：vertical height of bone graft retention（58.82±8.17）%,ISQ 75.36±3.72;Group（freeze-dried human bone）：vertical height of bone graft retention（61.81±10.26）%,ISQ 78.20±3.77;Group（β-TCP＋ freeze-dried human bone）：vertical height of bone graft retention（60.56±7.06）%,ISQ 75.06±4.20.No difference was found in each group.Conclusions Three kinds of sinus graft materials have good preliminary clinical results for the sinus augmentation technique and simultaneously placement of implants.
