【摘要】 目的:以牙周引导再生术(GTR)观察胶原膜与Bio-Oss和HA联合治疗Ⅱ～Ⅲ度根分叉病变的疗效。方法:选53例根分叉区病变的患牙65个,分HA+GTR及Bio-Oss+GTR二组,术后以定性及定量指标对比分析疗效。结果:与术前相比两组术后牙周袋深度(PD)、根分叉水平探入深度(HPD)、附着丧失(AL)、牙龈指数(GI)均明显减少,且有显著性差异(P<0.05);Bio-Oss+GTR组PD值低于HA+GTR组(P<0.05)。两组骨缺损处均有明显新生牙槽骨。结论:Bio-Oss和HA联合GTR治疗Ⅱ～Ⅲ度根分叉病变,可获得良好的临床疗效,Bio-Oss稍优于HA。更多还原

【Abstract】 AIM :To observe the effect of therapy on furcation involved teeth by HA and Bio-Oss with GTR.METHODS:65 teeth with Ⅱ～Ⅲ° furcation involvement in 53 cases were selected and divided into two groups.One was treated by HA with GTR while the other group was treated by Bio-Oss with GTR.The result of treatment was analysed.RESULTS:The following periodontal index including PD、HPD、AL、GI were significantly reduced in both groups pre and post-operation(P<0.05).The reduction of the PD in Bio-Oss group were more significant than that in the HA group(P<0.05).The amount of alveolar bone was obviously increased in two groups.CONCLUSION:There were satisfactory clinical results when treated by Bio-Oss and HA with GTR.However,the Bio-Oss is superior to the HA.更多还原
