摘　　要：目的:比较玻璃纤维桩树脂核和金属铸造桩核修复上颌前牙残根残冠的临床疗效。方法:选择2008年1月-2011年12月我院200例上颌前牙残根残冠患者,随机分为观察组与对照组,每组100例,观察组采用玻璃纤维桩树脂核修复,对照组采用金属铸造桩核修复,比较两组患者患齿修复成功率、修复后1、2年咀嚼效能有效率、修复前后患齿健康指数。结果:1观察组患者因牙龈炎、牙龈着色、冠折/根折、全冠松动/脱落、桩核松动/脱落而失败的发生率为2.0%、2.0%、1.0%、2.0%、1.0%,均低于对照组的6.0%、7.0%、5.0%、7.0%、5.0%,观察组总成功率为94.0%,显著高于对照的74.0%,两组数据比较差异均有统计学意义(均P<0.05);2观察组修复后1、2年咀嚼功能改善有效率分别为94.0%、86.0%,对照组分别为89.0%、72.0%,比较差异均有统计学意义(均P<0.05);3两组患者修复后抗折裂强度、GI、SBI均较修复前明显改善,比较差异有统计学意义(均P<0.05),观察组修复后抗折裂强度、GI、SBI较对照组改善更明显,比较差异有统计学意义(均P<0.05)。结论:玻璃纤维桩树脂核修复上颌前牙残根残冠具有较高成功率,咀嚼功能改善明显,临床效果优于金属铸造桩核修复。Objective： To compare the clinical efficacy of glass fiber post and resin core and metal casting post and core in repairing maxillary anterior residual roots and crowns. Methods. 200 cases of patients with maxillary anterior residual roots and crowns who were treated in our hospital from January 2008 to December 2011 were selected, and were randomly divided into the observation group who were given glass fiber post and resin core and the control group who were treated with metal casting post and core, with 40 cases in each group. The success rate of repairing of suffering tooth, masticatory efficiency after the restoration of 1, 2 years, health index before and after restoration were compared between the two groups. Results： （1）The incidence rates of repair failure of the gingivitis, gingival coloration, fold crown / root fracture, crown loose or off, post and core loose or off of the observation group were lower than those of the control group （2.0%, 2.0%, 1.0%, 2.0%, 1.0% vs 6.0%, 7.0%, 5.0%, 7.0 %, 5.0%）, the total success rate （94.0%） in the observation group was higher than that （74.0%） of the control group, the difference was statistically significant （all P〈0.05）; （2）The effective improvement rate of masticatory fimction of the observation group after restoration of 1, 2 years were 94.0% and 86.0%, while that of the control group were 89.0% and 72.0%, and the difference was statistically significant （all P 〈0.05）; （3） The anti-fracture strength, GI, and SBI after restoration of the two groups were significantly improved compared with before restoration, and the difference was statistically significant （all P 〈 0.05）, the anti-fracture strength, GI, SBI after restoration of the observation group were significantly improved than the control group, the difference was statistically significant （all P〈0.05）. Conclusion： Glass fiber post and resin core has high success rate in the repaire of maxillary anterior residual roots and crowns, it effectively improve
