摘要
目的探讨玻璃纤维桩联合全瓷冠修复前牙牙体缺损的临床疗效。方法将我院收治的因前牙缺损行美容修复的患者52例(136颗牙)随机分为治疗组(26例70颗)和对照组(26例66颗)两组,在根管治疗后分别采用玻璃纤维桩全瓷冠修复和铸造桩加钴铬烤瓷冠修复。观察两组修复成功率,对修复前后局部龈沟液(GCF)和龈沟液中碱性磷酸酶(ALP)水平进行检测,并对患者随访1年,评估其远期疗效。结果治疗组和对照组的修复成功率分别为95.7%、90.0%(P>0.05);治疗后4周、12周,对照组局部GCF、ALP水平均较治疗前显著升高,且显著高于同期治疗组的水平(P<0.05),而治疗组治疗前后比较差异无统计学意义(t=0.65,0.74,P>0.05);治疗1年后,治疗组的修复体完整度、边缘适合度、颜色匹配均显著优于对照组(P<0.05)。结论玻璃纤维桩联合全瓷冠进行修复对牙周组织刺激较小,具有良好的美学及生物学特性,是一种理想的前牙牙体缺损修复方法。
Objective To explore the effect of glass fiber pile combined with all-ceramic crown in restoration for defect of anterior teeth.Methods Fifty-two patients with 136 defective anterior teeth were divided into two groups：the treatment group（26 patients,70 teeth） and the control group（26 patients,66 teeth）.After root canal therapy,the treatment group was given glass fiber pile combined with all-ceramic crown,while the control group was given cobalt-chromium-cobalt-chromium cast piles porcelain crown.The success rate was observed,gingival crevicular fluid（GCF） and alkaline phosphatase（ALP） were detected,and the long-term effect was evaluated after one year follow-up.Results There was no significant difference in the success rate between the two groups（95.7% vs 90.0%）,P0.05.After treatment for 4 weeks and 12 weeks,the levels of GCF and ALP was significantly increased in the control group compared with before treatment,while there was no significant difference on these indicators in the treatment group before and after treatment（t=0.65,0.74,P0.05）.The levels after treatment were significantly higher in the control group than the treatment group（P0.05）.After restoration for 1 year,the integrity,marginal adaptation,and color match in the treatment group were all significantly better than those in the control group（P0.05）.Conclusion Glass fiber pile combined with all-ceramic crown has relatively small stimulation on periodontium,with good aesthetic and biological characteristics,which can be used as an ideal restoration method for defect of anterior teeth.
