摘要:

背景:临床上多采用平行或锥形玻璃纤维根管桩修复根管治疗后的残根残冠,但两种形态根管桩的临床效果还有待证实。
目的:评价残冠修复时使用平行及锥形玻璃纤维根管桩的临床疗效。
方法:选择残冠患者121例,共156颗患牙,经完善的根管治疗后采用掷硬币法随机分为两组,分别采用平行玻璃纤维根管桩与锥形玻璃纤维根管桩重建桩核,然后以全瓷或金属烤瓷冠修复。术后每半年复查1次,分别对修复体的稳固性、边缘密合性、牙周组织情况、咬合功能等方面进行临床评价,观察期为2年。
结果与结论:121例患者均完成2年的随访观察。平行玻璃纤维根管桩组根管桩自牙颈部折断1例,治疗成功率为98.7%;锥形玻璃纤维根管桩组根管桩折断1例,根管桩连同全冠完整脱落1例,经重新粘接后行使功能良好,治疗成功率为97.5%;两组间治疗成功率差异无显著性意义(P > 0.05)。说明两种形态的玻璃纤维根管桩均可取得令人满意的临床效果,但远期疗效尚有待进一步观察。

Abstract:

BACKGROUND: More and more structurally compromised teeth are restored with either tapered or parallel-sided glass fiber reinforced posts. While the clinical effect on the restoration with different-shape posts still need to be confirmed.
OBJECTIVE: To investigate the clinical effectiveness over 2 years of parallel-sided and of tapered glass-fiber posts to restore structurally compromised teeth.
METHODS: The study population was composed of 121 patients with 156 endodontically treated teeth. They were divided into two groups randomly and restored by the post-and-core technique with either tapered or parallel-sided glass-fiber posts. The final full crowns were either all-ceramic or porcelain-fused-to-metal crowns. The restorations were examined clinically and radiologically every half year. The inspection items included the retention and sealing property of restorations, state of periodontaltissue and occlusal function. The total observation period was 2 years.
RESULTS AND CONCLUSION: All the patients completed the 2-year clinical investigation. One parallel post was broken at cervical level. In the taper post group, one post was broken and one restoration fall off. The survival rate for parallel-sided posts was 98.7% and for tapered posts was 97.5%. There was no significant difference between these two groups (P > 0.05). It indicated that both parallel-sided posts and tapered posts could achieve satisfactory clinical performance in 2-year follow-up, while long-term effects still need to be observed.
