摘　　要：目的评价2种不同纤维夹板固定牙周炎所致下前牙松动牙的临床疗效。方法选取符合病例纳入标准的44例中重度牙周炎患者随机分为2组,每组22例,分别应用BIOSPLINT固位纤维和Fiber-splint ML玻璃纤维2种牙周纤维夹板对下前牙进行松牙固定治疗,并对2组患者治疗后3、6和12个月的临床疗效及各项牙周指数进行比较,采用SPSS16.0软件包对数据进行统计学分析。结果 BIOSPLINT固位纤维固定6个月后,探诊深度、附着丧失程度较固定前显著改善(P<0.05);菌斑指数、牙龈指数在固定3、6、12个月后,与固定前比较无显著差异。Fiber-splint ML玻璃纤维组固定6个月后,探诊深度、附着丧失程度均比之前有所好转(P<0.05),菌斑指数、牙龈指数在固定6个月后高于固定前(P<0.05)。固定后3个月,牙周各项指标在2组间差异(P>0.05)。固定6个月后,BIOSPLINT固位纤维组与Fiber-splint ML玻璃纤维组的附着丧失程度和探诊深度检测状况组间差异(P>0.05),而Fiber-splint ML玻璃纤维组的菌斑指数和牙龈指数较BIOSPLINT固位纤维组高,差异有统计学意义(P<0.05)。结论2种牙周夹板均可有效的保存松动患牙,与Fiber-splint ML玻璃纤维相比,采用BIOSPLINT固位纤维用于牙周炎松动牙固定,更有利于患者维护口腔卫生,保持牙周健康。Objective To evaluate the clinical effects of two kinds of different fiber splints for splinting the mandibular anterior loose teeth after periodontal treatment. Methods A total of 44 patients with moderate and severe periodontitis were randomly divided into a BIOSPLINT splinting ribbon group and fiber-splint ML group. After periodontal treatment, the loose teeth were fixed by two kinds of fiber splints. After 1 year of clinical observation, probing depth（PD）,attachment loss（AL）, plaque index, gingival index（GI）and plaque index（PLI）were measured. The data was analyzed with SPSS 16.0 software package. Results Six months after the fixation, PD and AL became shallower（P〈0.05）, however, no significant difference was observed in GI and PLI in the BIOSPLINT splinting ribbon group. In the fiber-splint ML group,PD and AL became shallower, and the GI and PLI values were higher（P〈0.05）. GI and PLI in the fiber-splint ML group were higher than that in the BIOSPLINT splinting ribbon group six months after the fixation（P〈0.05）. Conclusion The two kinds of periodontal splints both are effective in preserving loosen teeth. The effect in BIOSPLINT splinting ribbon group is significantly better than that in the fiber-splint ML group.
