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 metal post to repair the residual crown of the maxillary anterior teeth. Methods: From January 2008 to December 2011, 200 patients with residual residual root crown of maxillary anterior teeth in our hospital were randomly divided into observation group and control group, with 100 cases in each group. The observation group was treated with glass fiber post and resin core, The group was treated with metal cast post and core restoration. The successful rate of repairing the affected teeth was compared between the two groups. The effective rate of masticatory efficiency in one and two years after repair and the index of healthy teeth before and after restoration were compared. The incidence of failure in the observation group was 2.0%, 2.0%, 1.0%, 2.0% and 1.0%, respectively, due to gingivitis, gingival coloration, capsular / root fractures, total crown loosening / , Respectively, were lower than the control group 6.0%, 7.0%, 5.0%, 7.0%, 5.0%, the total success rate of the observation group was 94.0%, significantly higher than the control 74.0%, the two groups were statistically significant differences (P <0.05) .2 The effective rates of improvement of mastication in the observation group at 1 and 2 years after repair were 94.0% and 86.0%, respectively, and 89.0% and 72.0% respectively in the control group (all P <0.05 ); 3 The flexural strength, GI and SBI of the two groups after repair were significantly improved compared with those before the repair (all P <0.05). The fracture strength, GI and SBI of the observation group were better than those of the control The improvement of the group was more obvious, the difference was statistically significant (all P <0.05). CONCLUSION: The fiberglass-reinforced resin core has a higher success rate of repairing the residual crown of the maxillary anterior teeth and the improvement of chewing function. The clinical effect is better than that of the metal-cast post-core restoration.
