摘　　要：目的研究对比Bio-Oss&PerioGlas在上颌前牙区种植体周围骨缺损中的成骨能力及成骨效果。方法选取上颌前牙区种植体周围骨缺损患者20例,共植入32枚种植体,分别植入Bio-Oss和PerioGlas两种骨替代材料,于术后6个月行种植体上部永久冠修复。手术完成后随访1年,统计种植体存留率。通过红色美学指数(PES)、边缘骨水平(MBL)、唇腭侧骨板宽度、患者满意度,评价种植修复后成骨能力及效果。结果种植体存留率均为100%。软组织情况较好,PES差异无统计学意义。两种骨替代材料术后与术后6个月的唇腭侧骨板宽度改变量差异有统计学意义,术后6个月与术后12个月的唇腭侧骨板宽度改变量差异无统计学意义。两种骨替代材料的术后6~12个月的边缘骨水平改变量差异无统计学意义。结论在上颌前牙区种植体周围骨缺损中,Bio-Oss和PerioGlas均具有良好的成骨能力及成骨效果,通过比较发现Bio-Oss吸收较慢,有利于唇侧骨壁宽度的维持,具有较好的美学效果。Objective To study the osteogenic ability and effect of Bio-Oss & PerioGlas in the peri-implant bone defects of maxillary anterior teeth.Methods Twenty cases of peri-implant bone defects of maxillary anterior teeth were selected to graft with two kinds of bone substitutes Bio-Oss & PerioGlas respectively,with a total number of 32 implants.The permanent crown restoration was performed 6 months after operation.One-year follow-up after operation was made to evaluate the osteogenic ability and effect after implant-supported prostheses through recording implant survival rate,pink esthetic scores(PES),marginal bone level(MBL),width of the labial and palatal bone and satisfaction of the patients.Results The survival rates were 100%.Soft tissue recovered well and showed no statistical significance in the difference of PES.There were statistical significant differences between two bone substitutes' width of the labial and palatal bone changes after operation and 6 months after operation; bone substitutes' width of the labial and palatal bone changes had no statistical significant differences between 6 months and 12 months after operation; MBL change had no significant difference between 6 and 12 months after the operation.Conclusions Bio-Oss and PerioGlas both had good osteogenic ability and effect in the peri-implant bone defects of maxillary anterior teeth,but the absorption of Bio-Oss was slow,which was beneficial to the maintenance of width of the labial bone and had a good esthetic effect.
