摘要
目的:对比A-PRF、胶质银、Bio-Oss骨粉3种不同材料在凹面型上颌窦底外提升术同期种植病例的临床效果。方法:选择108例上颌后牙区剩余骨高度不足且上颌窦底形态为凹面型的患者,随机分为A-PRF(A)组、胶质银(B)组与Bio-Oss骨粉对照(C)组,上颌窦底外提升术同期植入种植体145枚,比较3组术后反应程度及术后4、6、12个月上颌窦内新生骨密度。结果:A组、B组、C组3组间比较,术后反应程度无明显差异(P>0.05)。术后4个月,上颌窦内新生骨密度C组明显高于同期A组和B组(P<0.05),A组明显高于B组(P<0.05),且A组已达术前水平;术后6、12个月各组骨密度均无明显差异(P>0.05)。结论:A-PRF可以促进上颌窦内早期新骨形成,单独用于凹面型上颌窦底外提升术同期种植的病例中,能取得良好的临床效果。
Objective:To compare the clinical effect of A-PRF,gelatin sponge and Bio Oss bone powder in the same period of implant placement in concave maxillary sinus floor external lift surgery.Methods:108 patients with insufficient height of residual bone in maxillary posterior area and concave shape of maxillary sinus floorwere randomly divided into A-PARF group(A),gelatin sponge group(B)and Bio Oss bone powder control group(C).145 implants were implanted at the same time.The degree of postoperative reaction and the new bone density in maxillary sinus at 4,6 and 12 months were compared among the three groups.Results:The degree of postoperative complications was no obvious difference in the 3 groups(P>0.05).The group C of the HU was significantly higher than the group A and B at 4 m after the operation(P<0.05).The group A of the HU was significantly higher than the group B at 4 m after the operation(P<0.05),but the group A of the HU at 4m was close to the preoperative HU.There was no difference in the 3 groups at 6 m,12 m(P>0.05).Conclusion:A-PRF can promote the early formation of new bone,and can achieve good clinical results in the cases of simultaneous implantation of sinus-lifting operations which the sinus floor is concave by using A-PRF alone.
