背景：当冠部牙体组织大面积缺损单纯充填、全冠及嵌体疗效不佳时，桩核系统使残根、残冠的修复成为可能。目的：分析玻璃纤维桩和铸造金属桩在牙体缺损修复中的临床效果。方法：将106例患者共160颗患牙随机分为2组，经完善的根管治疗后，分别采用玻璃纤维桩(n=80)和铸造金属桩(n=80)制作桩核，金瓷冠修复，随访9-33个月，评价两组临床修复效果。结果与结论：玻璃纤维桩治疗成功78颗，桩松动2颗，治疗成功率98%；铸造金属桩治疗成功71颗，冠折1颗，根折4颗，桩脱落4颗，治疗成功率89%，两组治疗成功率比较差异有显著性意义(P<0.05)。表明玻璃纤维桩在牙体缺损修复中具有操作方便、色泽好且不易造成根折等优点，治疗效果优于金属铸造桩核修复。
揹景：噹冠部牙體組織大麵積缺損單純充填、全冠及嵌體療效不佳時，樁覈繫統使殘根、殘冠的脩複成為可能。目的：分析玻璃纖維樁和鑄造金屬樁在牙體缺損脩複中的臨床效果。方法：將106例患者共160顆患牙隨機分為2組，經完善的根管治療後，分彆採用玻璃纖維樁(n=80)和鑄造金屬樁(n=80)製作樁覈，金瓷冠脩複，隨訪9-33箇月，評價兩組臨床脩複效果。結果與結論：玻璃纖維樁治療成功78顆，樁鬆動2顆，治療成功率98%；鑄造金屬樁治療成功71顆，冠摺1顆，根摺4顆，樁脫落4顆，治療成功率89%，兩組治療成功率比較差異有顯著性意義(P<0.05)。錶明玻璃纖維樁在牙體缺損脩複中具有操作方便、色澤好且不易造成根摺等優點，治療效果優于金屬鑄造樁覈脩複。

BACKGROUND:The post and core system for residual roots and crowns can achieve satisfactory effects, when fil ing restoration, ful crowns or inlay has poor effects. OBJECTIVE:To evaluate the clinical use of glass fiber post and metal post in the restoration of endodontical y treated teeth. METHODS:A total of 106 patients with 160 endodontical y treated teeth were selected and restored with glass fiber post (n=80 teeth) and metal post (n=80 teeth) fol owed by porcelain-fused-mental crown. The restorations were evaluated clinical y for 9 to 33 months. RESULTS AND CONCLUSION:Glass fiber post treatment for 78 teeth was effective and that for two teeth were failed, with a successful rate of 98%. Metal post restoration was effective in 71 teeth and failed in nine teeth including one tooth of crown fracture, four of root fracture and four of post loss, with a successful rate of 89%. There was statistical y significant difference between two groups (P<0.05). Glass fiber post is better in convenient handling and good color and reduced probability leading to root broken for dental restoration compared with metal post.
