摘要
目的比较三种桩核冠的临床修复效果,为严重缺损患牙的修复提供参考。方法采用镍铬合金铸造桩核(Ⅰ组)修复患牙39个,预成金属桩/树脂核(Ⅱ组)修复患牙27个,玻璃纤维桩/树脂核(Ⅲ组)修复患牙50个,三组都用烤瓷全冠修复外形。一年后复查修复体完好情况。结果成功率Ⅰ组94.9%,Ⅱ组96.3%,Ⅲ组98.0%,三组间无显著差异(P>0.05)。玻璃纤维桩在综合评价中有优势。结论玻璃纤维桩有良好的临床应用前景,远期疗效尚待观察。
Objective To compare the clinical effect of three post-core-crown systems so as to make reference for repairation of bad- ly damaged teeth. Methods Ni-Cr alloy casting post-core （group Ⅰ ） used in 39 teeth, preformed metal post/resin core in 27 teeth （group Ⅱ ）, glass fiber post/resin core （group Ⅲ） in 50 teeth, metal-porcelain full crown had been applicated on all of them. Investigation had been made in 1 year. Results The successful rate was 94.9% （groupⅠ ）, 96.3% （group Ⅱ ）, or 98.0% （group Ⅲ ）. No significant difference was found in three systems （P〉0.05）. Conclusion The prospects of glass fiber post will be bright, yet a longer time observation is needed.
