摘　　要：目的:探讨采用复合树脂高强纤维修复牙周病伴牙列缺损的临床疗效。方法:选择30例经过完善牙周治疗并伴下前牙区牙列缺损的患者,使用EverStick复合树脂高强纤维直接法制作下前牙牙周夹板并修复其前牙缺失。修复后1、6个月、1、2 a复诊,对临床修复效果进行评价,并检查患者牙周情况和菌斑控制情况,记录治疗前及每次复诊时的菌斑指数(PLI)、牙龈指数(G1)、探诊深度(PD)。采用SPSS17.0统计软件包进行成组t检验和x^2检验。结果:PLI和GI在治疗后1、6个月、1 a和2 a时差异无显著性(P>0.05);PD在治疗后1个月与6个月时逐渐变浅,其差异具有显著性(P<0.05),6个月与1、2 a相比差异无显著性(P>0.05),治疗后各时间点与治疗前相比均降低(P<0.05)。患者对牙周夹板黏结桥的美观、发音、舒适及咀嚼功能的满意度为80%以上。结论:下前牙牙周炎伴牙列缺损病例采用FRC技术修复缺失牙,既可有效固定松动牙,使之符合生理功能的要求,又可为患者提供较为舒适与美观的修复体;每隔6个月1次的牙周维护治疗,是影响其治疗效果的重要因素。PURPOSE： To evaluate the effect of fiber reinforcement composites （FRC） in treating chronic periodontitis with dentition defect. METHODS： Thirty patients who had chronic periodontitis and missed less than 2 lower anterior teeth were chosen. After appropriate periodontal treatment, EverStick fibers were used to fabricate splint with the missing teeth repaired. One month, 6 months, 1 year and 2 years after treatment, periodontal indexes such as plaque index （PLI）, gingival index （GI） and probe depth （PD） were recorded and the patients＇ satisfaction was evaluated. SPSS 17.0 software package was used for statistical analysis. RESULTS： The results showed that no significant difference was found in PLI and GI during observation period （P〉0.05）. PD decreased significantly after 6 months of observation （P〈0.05）. Patients＇ satisfaction degree for aesthetics, pronunciation, comfort and function was beyond 80%. CONCLUSIONS： Using FRC technique in chronic periodontitis with dentition defect can effectively fix the loosen teeth and maintain physical function. Appropriate periodontal treatment every 6 months is the key factor for satisfactory results.
