摘要
目的:探讨玻璃纤维桩核与金属烤瓷全冠修复后牙残冠、残根的临床效果。方法:选取100例(18～60岁)后牙残冠、残根患者,共计195颗患牙,经过完善的根管治疗后随机分为2组,实验组50例患者共95颗患牙,植入玻璃纤维桩核;对照组50例患者共100颗患牙,用金属铸造桩核修复。2组患者均用金属烤瓷全冠恢复牙体外形。观察2组患者的修复体形态、功能和成功率,并用SPSS13.0软件包对2组修复体的成功率进行χ2检验。结果:随访36个月,实验组共90颗牙咀嚼功能良好,无不适主诉,修复体牢固,牙龈及根尖无明显炎症,占总数的94.74%,而对照组100颗牙获得85.00%的成功率,2组差异有显著性意义(P<0.05)。结论:玻璃纤维桩核可以作为理想的后牙残冠、残根桩核修复材料。
PURPOSE： The aim of this prospective randomized controlled trial is to evaluate the clinical effect of glass fiber-reinforced post core applied in the restoration of premolar or molar residual crown and root. METHODS： 195 residual crown and root of posterior teeth from 100 patients, aged from 18 to 60 years, were included in the study. Among 195 teeth, 95 teeth in the experimental group were restored with glass fiber-reinforced post core, while the other 100 teeth in the control group were restored with metal cast post core. All the teeth were then restored with porcelain fused metal crown. The esthetical property, function, and survival rate of the prostheses were observed. The data was analyzed with SPSS13.0 software package for χ^2test. RESULTS： The prostheses were followed up in this clinical study for a period of up to 36 months. In the experimental group, there were a total of 90 teeth with excellent chewing function, no complaint of discomfort, no debounding, no gingivitis or periapical periodontitis. The success rate of the experimental group was 94.74%, while that of tile control group was 85.00%. The difference of the success rate between two groups was statistically significant （P〈0.05）. CONCLUSION： Glass fiber-reinforced post core can be used as an ideal restoration material for the premolar or molar residual crown and root.
