摘　　要：目的：比较纤维桩和螺纹桩修复残根残冠的成功率，为临床预成桩的应用提供依据。方法：随访近3～5年用纤维桩和螺纹桩修复后的残根残冠，共309例，比较两组的成功率。结果：纤维桩组成功率为98．56％，螺纹桩组成功率为95．88％，经统计学分析，两组无统计学意义。根据不同牙位，纤维桩修复前磨牙的成功率最低（96．88％），磨牙的成功率最高（100％）；螺纹桩修复前牙的成功率最低（92．86％），磨牙的成功率最高（97．98％），经统计学分析，不同牙位之间无统计学意义。结论：只要设计合理，前牙和后牙均可用纤维桩或螺纹桩制作桩核，为了美观需要，前牙建议使用纤维桩。Objective： To compare the clinical effect of the teeth restored with fibre post and screw post. Methods： Followed--up the residual roots and crowns restored with the fibre post and screw post a total of 309 cases were se lected for the past 3--5 years. We compared the success rate of the two groups. Results： The success rates of fibre post group and screw post group were 98.56% and 95.88%. There was no significant difference between the two groups. According to the tooth--type, premolars had the lowest success rate （96.88 %） and molars had the highest success rate （100% ） in the fiber post group. Front teeth had the lowest success rate （92.86 % ）and molars had the highest success rate （97.98%）in the screw post group. There was no significant difference between the different tooth types. Conclusion： As long as the design is reasonable , the anterior and posterior teeth can be restored with fiber post or screw post. Front teeth were recommended to use the fibre posts for aesthetic needs.
