摘　　要：目的研究对比Bio-Oss和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2015—2016年就诊于我院种植中心的上颌前牙区种植体周围骨缺损患者20人,其中女性8人,男性12人,共植入32枚种植体,分别植入Bio-Oss和PerioGlas两种骨替代材料,并于术后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。所有患者均于术前、术后、术后6个月、术后12个月拍摄CBCT,并通过红色美学指数(Pink Esthetic Scores,PES)、边缘骨水平(Marginal Bone Level,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,红色美学指数差异不具有统计学意义。两种骨替代材料术后与术后6个月的改变量的差异具有统计学意义,术后6个月与术后12个月的改变量的差异不具有统计学意义。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不具有统计学意义。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 20 cases （ 12 male, 8 female） of anterior teeth trauma are selected from pa- tients treated fi＇om 2015 to 2016, with a total number of 32 implants, which were selected to graft with two kinds of bone sub- stitutes ＇Bio -Oss ＆ PefioGlas＇ respectively, with a total number of 32 implants. The permanent crown restoration was per- formed 6 months after operation. 1 year follow - up after operation was made to evaluate the osteogenic ability and effect after implant - supported prostheses through implant survival rate, PES, MBL, width of the labial and palatal bone and satisfaction of the patients. All the patients were required to scan CBCT before operation, after operation, 6 months after operation, and 12 months after operation. Results The survival rates were 100%. Soft tissue recovers well and shows no statistical signifi- cance in the difference of PES. There was statistical significant difference between two kinds of bone substitutes＇ changes after operation and 6 months after operation. It shows no statistical significant difference between 6 months and 12 months after op- eration. Also there was no significant difference in the change of MBL between 6 and 12 months after the operation. Conclu- sion Bio - Oss and PerioGlas both have good osteogenic ability and effect in the peri - implant bone defects of maxillary an- terior teeth. By comparison, it was found that 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.
