目的探讨用高强度玻璃纤维桩核修复烤瓷冠基牙折断再修复的效果。方法选择11例15颗基牙折断的烤瓷牙,去除折断于烤瓷冠内的牙体组织,经完善根管治疗后,按要求行牙体预备,制作玻璃纤维桩核,并用原烤瓷冠进行修复。结果 15颗患牙,经过0.5 a1、a、2 a随访观察,所有修复体功能良好,无龈炎、根折及根尖周炎表现。结论烤瓷冠修复后基牙折断采取高强度玻璃纤维桩核再修复的方法简便易行,临床效果良好。
Objective To investigate the effect of repairing the abutments of porcelain fused to titanium crowns by means of high strength glass fiber posts. Methods Eleven cases of porcelain teeth broken off by 15 abutments were selected to remove the tooth tissue broken in the porcelain crowns. After the complete root canal treatment, the dental preparations were prepared according to the requirements and the glass fiber post cores were made. Crown to repair. Results Fifteen teeth were observed with 0.5 a1, a, and 2 a follow-up. All the prosthesis was well-functioning without gingivitis, root fracture and periapical periodontitis. Conclusion The method of repairing the abutment teeth after the restoration of the porcelain crown by high-strength glass fiber post-core is simple and easy, and the clinical effect is good.
