摘要
目的:评价自体骨夹层法修复种植体周围骨缺损的近期临床效果。方法:48例患者共82颗种植体,植入的种植体唇侧骨壁缺损,其余三个骨壁都存在,随机分为两组:一组为混合法,22例患者39颗种植体,自体骨粉与Bio-Oss骨粉按1:1比例混合修复骨缺损部位。另一组为夹层法,26例患者43颗种植体,局部微量刮取自体骨粉涂于暴露的种植体表面,再覆盖Bio-Oss骨粉,再覆盖生物膜。植入6个月后行上部修复。修复后追踪时间平均24个月。根据临床、X线检查和患者主诉评价修复效果。结果:两组均无种植体脱落,存留率100%,二者差异无统计学意义。其龈袋深度、出血指数、年累计骨吸收量及X线检查均无明显不同。结论:对于骨缺损的病例,采用自体骨夹层法可以应用于临床。近期效果良好,长期效果有待追踪。
Objective：To investigate the effect of Sandwich method by using local autologous bone powder to repair bone defect around dental implants.Methods：48 patients with labial wall bone defect are randomly divided into two groups,a total of 82 implants are placed.The mixture method is used by one group with 22 patients 39 implants.The autologous bone is mixed with Bio-Oss bone powder as the rate of 1：1 and is used to repair the labial wall bone defect.The sandwich method is taken by another group with 26 patients 43 implants.In this group,some autologous bone powder is scraped aroud the area of bone defect and laid on the exposed implant surface,then Bio-Oss powder is placed and Bio-Gide is covered.At last the Operative incision is well sutured.Porcelain crowns are placed properly after 6 months,and the effect is evaluated by chief complaints of patients,clinical and radiological examination for an average of 24 months.Results：All implants are stable in both two groups.The implant survival rate is 100%.There is no significant difference between the two groups in perio-implant gingival bleeding index,probing depth,radiological examination results and bone resorption.Conclusion：Sandwich method by using local autologous bone powder is very effective for the patients with bone defect,the perfect short-term effects are obtained and long-term effects need to be followed up.
