不同桩核修复前牙牙体缺损的临床疗效观察

Observation for clinical effects of different post in anterior teeth restoration

目的:观察并比较纤维桩和铸造金属桩在前牙牙体缺损修复中的临床疗效。方法:选取130颗需行桩冠修复的前牙,分别用玻璃纤维桩(A组,65颗)和铸造金属桩(B组,65颗)制作桩核,烤瓷全冠进行修复,患者随访2年,观察其临床修复效果。结果:纤维桩组的桩核冠松动脱落1例,铸造金属桩组桩核冠松动脱落8例,差异有统计学意义(P<0.05);纤维桩组与铸造金属桩组桩核折断各1例,差异无统计学意义(P﹥0.05);纤维桩组未发生根折,铸造金属桩组根折7例,差异有统计学意义(P<0.05);纤维桩组与铸造金属桩组均未继发根尖周炎。结论:纤维桩在前牙牙体缺损修复中具有操作方便,色泽好等优点,优于铸造桩核。

Objective ：To observe the clinical effects of glass fiber post and metal post in anterior teeth restoration. Methods： Glass fiber posts （groupA,65 teeth） and metal posts （ groupB, 65 teeth） were used for 130 anterior teeth restora- tion. After two - year follow - up, they were observed the restoration effect. Results ： There was significant difference （P 〈 0.05） of crown loss between glass ~ber posts and metal posts. There was no statistical significance （P 〉 0.05） of the frac- ture rate of post - core between glass fiber posts and metal posts. There was significant difference （P 〈 0.05 ） of root frac- ture between glass fiber posts（none） and metal posts. These two groups all didnt have secondary pefiapical periodontitis. Conclusion： Glass fiber post is better in convenient handling and good eolour for anterior teeth restoration compared with metal post.
