摘要
目的:比较玻璃纤维桩与贵金属桩应用于前牙大面积牙体缺损修复的效果.方法:选取78例患者150颗已接受完善根管治疗的前牙牙体缺损患牙,根据患者对材料不同的选择,分为纤维桩组及金属桩组,每组75颗,后续均使用氧化锆全瓷冠修复.比较2组修复前、修复后4周、6个月、1年、2年和3年的局部龈沟液(GCF)水平以及龈沟液中碱性磷酸酶(ALP)水平;比较两组随访3年后的修复体完整性、龈缘颜色和边缘适合度.采用SPSS 19.0软件包进行统计学分析.结果:治疗后4周、6个月及1年,纤维桩组及贵金桩组GCF、ALP水平均显著高于治疗前(P<0.05),纤维桩组相对于贵金属桩组同期更高;治疗后2年和3年,贵金属桩组和纤维桩组之间GCF、ALP水平无显著差异:治疗后3年,纤维桩组修复失败率显著高于贵金桩组(P<0.05),牙龈透色及美观方面显著优于贵金桩组(P<0.05).结论:纤维桩及贵金属桩核用于前牙区大面积牙体缺损均有较好效果.对于牙颈部缺损较多的病例,选用贵金属铸造桩核,可减少修复体边缘微渗漏的可能.
PURPOSE:To analyze the effect and long-term success rate of using glass fiber post or metal post in restoration of anterior tooth defect.METHODS:One hundred and fifty cases with anterior tooth defects were chosen after root canal therapy in our hospital.According to different material being chosen,the patients were divided into fiber post group and metal post group with 75 cases in each group.Local gingival sulcus fluid(GCF)levels and alkaline phosphatase(ALP)level in gingival sulcus liquid were measured and compared 4 weeks,6 months,1 year,2 years and 3 years after restoration.Restoration integrity,edge fitness and color matching of two groups were compared after follow-up for 3 years.The data were analyzed with SPSS 19.0 software package.RESULTS:Four weeks,6 months,and 1 year after restoration,local GCF,ALP levels significantly elevated in both groups.The fiber post group showed more significant elevated levels of GCF and ALP than the metal post group(P<0.05).After 2 and 3 years,the difference between the two groups was not significant.The gingival color matching degrees were significantly better in the glass fiber post group after 1 year compared with that in the metal post group(P<0.05).The success rate of metal post group was significantly higher than that of fiber post group 3 years after restoration(P<0.05).CONCLUSIONS:Fiber post and metal post both have satisfactory restoration result for tooth defect in anterior teeth area.However,the use of precious metal alloy post may reduce the possibility of microleakage between tooth-prosthesis surfaces.
