摘要
目的玻璃纤维增强型复合树脂桩核人与金属铸造桩核修复后牙牙体缺损的临床效果比较。方法分别选取30例,共60颗,牙体严重缺损的第一磨牙,分别用玻璃纤维增强型复合树脂和铸造金属桩核(二步法)制作桩核,以金属烤修复牙体缺损,患者在3.6和12月后复诊,观察修复效果。结果1年中有2例2颗患者失访,在58颗复查患者中共有2颗患牙发生因桩核松动脱落,均为采用铸造金属桩核修复,而采用玻璃纤维桩核复合树脂桩核修复的患牙均未发生桩核树脂脱落,修复效果满意。结论玻璃纤维增强型复合树脂桩核在后牙牙体缺损的修复中,具有色泽好,操作方便,临床效果,优于铸造金属桩核。
Objective The clinical effect comparison of posterior dentine defect restoration with glassfiber strengthered composite resin post and metal post. Methods 60 seriously destroyed first molar of 30 cases were selected and treated with glrssfiber strengthered composite resin post and metal post, then porcelain-fused-metal crown （PFM） was applied to restore dentine defect. The patients were called back for a visit after 3.6 and 12 months. Results 2 molars of two cases lost visits. The other 58 molars have only two fails of metal post restoration eases, while all prosthesis of glassfiben strengthened composite resin post required satisfactory effect without failure. Conclusions Glassfiber strengthened composite resin post is a better choice than metal post in posterior dentine defect restoration with benefits such As perfect color, easy operation and satisfaetiory clinical effect.
