摘要: 目的 比较钴铬合金铸造桩核和everStick纤维桩在唇、舌向倾斜上颌中切牙改向修复中的临床疗效,为临床应用提供理论基础。方法 选择2012年3月—2014年3月治疗的唇、舌向倾斜上颌中切牙患者80例(97颗患牙),随机分为A组和B组,A组49颗,B组48颗。2组患者均进行改向桩核冠修复,A组患者桩核修复材料为钴铬合金,B组患者修复材料为everStick纤维桩。随访2 a,采用SPSS 19.0软件包对2种材料改向修复上颌中切牙后的牙根折裂、桩核折裂、冠或桩核松动脱落率、牙龈变色等指标进行对比分析。结果 χ2检验表明,2组患者修复成功率差异显著(P<0.05)。钴铬合金桩核组牙根折裂、牙龈变色显著高于everStick纤维桩组(P<0.05)。桩核折裂、冠或桩核松动方面2组相比差异无显著性(P>0.05)。结论 everStick纤维桩核在防止根折、牙龈边缘变色等方面优于钴铬合金铸造桩核。其断裂模式多为可修复性折裂,有利于患牙的保存。

Abstract: PURPOSE: To compare the clinical effect of Co-Cr alloy cast post-core and everStick fiber post in restoration of maxillary central incisor with labial or lingual inclination, and provide theoretical basis for clinical application. METHODS: Ninety-seven labially or lingually inclined maxillary central incisors were treated in our hospital from March 2012 to March 2014. The patients were randomly divided into group A (n=49) and group B (n=48), and received post -core and crown restoration. Patients in group A underwent Co-Cr alloy cast post and core restoration and patients in group B underwent everStick fiber post and core restoration. After two-year of follow-up, root fracture, post break, crown or post dislodgment and gingival marginal discoloration were recorded and analyzed using SPSS 19.0 software package. RESULTS: Chi-square test showed that the success rate of restoration was significantly different between 2 groups (P<0.05). The incidence of root fracture and gingival marginal discoloration of Co-Cr alloy cast post-core was higher than that of everStick fiber post, but there was no significant difference in the incidence of post break, crown or post dislodgment. CONCLTSIONS: EverStick fiber post is better than Co-Cr alloy cast post and core to prevent root fracture and gingival marginal discoloration. Its fracture pattern is repairable and favorable for preserving tooth.
