玻璃纤维桩树脂核和金属铸造桩核在上颌前牙残根残冠修复中的对比分析

摘要

目的:对比玻璃纤维桩树脂核和金属铸造桩核在上颌前牙残根残冠修复中的临床疗效.方法:选择上颌前牙患者120例患牙,随机分为两组,每组患牙60例,经过完善根管治疗后分别行玻璃纤维桩树脂核和金属铸造桩核修复.对修复后1年和2年患牙出血指数、基牙健康、咀嚼效能进行随访.结果:玻璃纤维桩树脂桩核组修复成功率95.00％,显著高于金属铸造桩核组的83.33％(P＜0.05);修复后1年咀嚼功能有效率与金属铸造桩核间差异无显著性(P＞0.05);修复2年有效率为88.33％,显著高于金属铸造桩核组(P＜0.05);修复后2年两组折裂强度较治疗前均显著提高(P＜0.05),与金属铸造桩核组间比较差异无统计学意义(P＞0.05);修复后2a GI和SBI分别为0.52±0.03和1.13-0.48,显著低于治疗前和金属铸造桩核组修复后水平(P＜0.05).结论:完善根管治疗后采用玻璃纤维桩核行上颌前牙残根残冠修复,成功率高、不良反应少,咀嚼功能好,综合临床显著优于铸造金属桩核修复.%Objective To investigate the clinical curative effect of the glass fiber-reinforced post and metal post on the residual roots and crown of maxillary anterior teeth.Methods 110 patients with120 cases maxillary anterior teeth were randomly divided into two groups,each group with 60 teeth.One group were performed with the glass fiber-reinforced post after perfect root canal therapy while the other group were performed with the metal post after perfect root canal therapy.The bleeding index periodontal health,masticatory efficacy and complications were followed investigated after 1 years and 2 years.Results The restored successful rate in the glass fiber post and resin core group was 95％ significantly higher than that of cast metal post and core group (P＜O.O5).The chewing functional efficiency after repair 1 year had no significant difference between two group while chewing functional efficiency after repair 2 year in the glass fiber post and resin core group significantly higher than that of the metal casting post and core group (P＜O.O5).The fracture strength of teeth in the glass fiberreinforced post group after the repair 2 years was significantly increased compared with before treatment (P＜O.05) while had no significant difference between two group (P＞O.O5).The GI and SBI of teeth in the glass fiber-reinforced post group after the repair 2 years were (0.52±0.03) and (1.13±0.48) was significantly lower than that before treatment and metal casting post and core group after the repair level(P＜O.05).Conclusion The using of the glass fiber-reinforced post after complete root canal therapy on the residual roots and crown of maxillary anterior teeth had high success rate,less adverse reaction and good chewing function.The comprehensive clinical was significantly better than the cast metal posts and cores.
