摘要:

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。

Abstract:

BACKGROUND: The post and core system for residual roots and crowns can achieve satisfactory effects, when filling restoration, full crowns or inlay has poor effects.
OBJECTIVE: To evaluate the clinical use of glass fiber post and metal post in the restoration of endodontically treated teeth.
METHODS: A total of 106 patients with 160 endodontically treated teeth were selected and restored with glass fiber post (n=80 teeth) and metal post (n=80 teeth) followed by porcelain-fused-mental crown. The restorations were evaluated clinically 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 statistically 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.
