摘要
目的评价玻璃纤维桩核与铸造金属桩核修复残根残冠及无桩修复根管治疗后残冠的生存率和并发症。方法 96名患者共142颗患牙进行根管充填,然后依据不同的情况进行玻璃纤维桩核、铸造纯钛桩核、无桩固位的全冠修复。结果在89名患者的135颗牙齿中,73颗牙齿(54.1%)使用玻璃纤维桩修复、复合树脂桩核,最后进行金瓷冠或全瓷冠修复,在(5.7±1.9)年平均观察期内的留存率达到97.3%;40颗牙齿采用铸造纯钛桩核修复,在(6.2±2.2)年平均观察期内的留存率达到了87.5%;22颗牙齿采用无桩修复,在(5.4±1.8)年平均观察期内的留存率是90.9%。玻璃纤维桩、铸造纯钛桩核、无桩修复的患牙三者间的成功率差异无统计学意义。修复最常见的并发症包括:根折(6.7%)、固位丧失(2.2%)、继发龋(1.5%)、根尖周炎(0.7%)。结论在实施高质量的根管治疗和规范的修复操作技术的前提下,无论是玻璃纤维桩修复还是铸造金属桩核修复或无桩修复的基牙在超过5年的观察期内均能获得较高的留存率,但并发症尤其是根折裂应引起必要的重视。
Objective To evaluate the survival rate and complications of endodontically treated residual crowns and roots restored directly or by glass fiber post and core or cast metal post and core. Methods In this study, 96 patients with a total of 142 teeth were selected. All the teeth were undergone root canal therapy. And then, according to different situations, some of them were restored with glass fiber post and core, another with cast metal post and core, the rest were restored directly in the strict controlled indications. Results The teeth（135） in 89 patients were divided into three groups. The first group contained 73 （54.1%） teeth restored with glass fiber post and composite resin core. The survival rate reached 97.3% in the average observation period of （5.7＋1.9） years. The second group contained 40 teeth, restored with pure titanium casting post and core. The survival rate reached 87.5% in the average observa- tion period of （6.2_＋2.2） years. The last group contained 22 teeth received no treatment. The survival rate reached 90.9% in the average observation period of （5.4_＋1.8） years. The success rate had no significant difference among the three groups. The most common complications after restored included root fracture （6.7%）, retention loss （2.2%）, se- condary caries （1.5%） and periapical periodontitis （0.7%）. Conclusion Under the premise of high quality root canal treatment and standard restoration treatment, the abutment teeth, whether are restored by glass fiber post and core, east metal post and core or without post, have a higher survival rate over 5 years of observation period and compli- cations especially root fracture still should attract the necessary attention.
