摘要:

目的 比较不同桩核修复方式和树脂直接充填入根管修复上颌前磨牙残根残冠后的临床效果,为临床工作提供指导。方法 78例患者93颗上颌前磨牙残根残冠进行完善的根管治疗后,根据不同的情况使用铸造金属桩核、纤维桩+树脂核、树脂直接充填后全冠修复,观察3年,通过临床和X线片检查,评估各种修复方式的临床效果。结果 3种修复方式成功率无明显差异。纤维桩+树脂核组、树脂直接充填入根管组常见的并发症为桩松动脱落、桩折裂,铸造金属桩核组常见的并发症为牙折裂。结论 3种修复方式均有较高的修复成功率,考虑到不可修复性牙折,应谨慎选用铸造金属桩核。

Abstract:

Objective To evaluate the clinical effects of maxillary premolars restored with different post-and-core systems and to provide guidance on clinical practice. Methods In this study, 78 patients with a total of 93 residual roots and crowns after root canal therapy were selected. According to different situations, some of them were restored with cast metal post and core, some with fiber post and resin core, and the others with resin filling to the root canal. All teeth systems through clinical and X-ray examinations. Results The success rate had no significant difference among the three groups. The common complications of the groups of fiber post and resin filling included dislocation and post fractures, whereas root fractures were observed in the group of cast metal post. Conclusion The three post-and-core systems all had high success rate. Given the unrestorable fractures, we should choose cast metal post and core restoration carefully.

Key words: post-and-core technique, post dislocation, post fracture, root fracture
