【摘要】：目的随着口腔种植修复技术日益成熟与发展,越来越多的人选择种植作为首选修复方式。特别在上颌前牙区的种植修复中,患者不仅需要考虑其功能作用,还要考虑其美学效果。本文研究对比Bio-OssPerio Glas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。方法在2014年到2016年间,选取就诊于安徽省口腔医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Perio Glas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)、唇腭向骨板宽度、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个月的唇腭向骨板宽度改变量的差异具有统计学意义,术后6个月与术后12个月的唇腭向骨板宽度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个月至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Perio Glas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。
[Abstract]:Objective with the development of dental implant technology, more and more people choose implant as their first choice. Especially in the implant restoration of maxillary anterior teeth, patients need to consider not only its function, but also its aesthetic effect. The osteogenic ability and osteogenic effect of Bio-OssPerio Glas in periimplant bone defects of maxillary anterior teeth were studied. Methods from 2014 to 2016, 20 patients (8 female and 12 male) with bone defects in the maxillary anterior dental region were enrolled in the implant center of Anhui Stomatological Hospital, and 32 implants were implanted. Two kinds of bone substitute materials, Bio-Oss and Perio Glas, were implanted, and the permanent crown was repaired 6 months after operation. All the patients were followed up for 1 year after operation, and the survival rate of implants was calculated. All the patients were photographed before operation, 6 months after operation, 12 months after operation, and evaluated the osteogenesis ability and effect of implant repair by means of pink esthetic score, marginal bone level, labiopalatine bone plate width, patient satisfaction. Results the survival rate of implants was 100. The soft tissue condition is good, the red esthetics index difference has no statistical significance. There was significant difference in the width of labiopalatine bone plate between the two kinds of bone substitute materials after operation and 6 months after operation, but there was no significant difference in the width of labiopalatine bone plate between 6 months after operation and 12 months after operation. There was no significant difference in the level of marginal bone between 6 months and 12 months after operation between the two kinds of bone replacement materials. Conclusion Bio-Oss and Perio Glas have good osteogenic ability and osteogenic effect in the bone defect around implants in maxillary anterior teeth. It is found that the absorption of Bio-Oss is slower, which is beneficial to the maintenance of the width of the labial bone wall and has a better aesthetic effect.
