摘要：

背景：在桩核的设计选择中，石英纤维桩因其良好的理化性能被认为是金属桩的良好替代品。
目的：评价MACRO-LOCK石英纤维桩树脂核全冠修复残根、残冠的临床疗效和安全性。
方法：将大面积前牙牙体缺损患者随机分为2组：石英纤维桩组患牙行完善的根管治疗后，利用MACRO-LOCK石英纤维桩、ULPDENT树脂黏接剂，PULPDENT双固化树脂核材料恢复桩核，以全瓷冠或贵金属烤瓷全冠修复。对照组患牙行传统的铸造金属桩核冠修复。随诊6个月及3年时的修复效果。
结果与结论：与对照组相比，石英纤维桩组RTD-MACOK POST石英纤维桩修复后随访3年仅1例发生桩核脱落，1例出现纤维桩折断，未出现根折现象，3年随访的成功率较高(P < 0.05)。结果证实，MACRO-LOCK石英纤维桩修复残根、残冠可获得良好的远期修复效果，安全性较好。

Abstract:

BACKGROUND: Because of the good physical and chemical properties, the quartz fiber post is considered as a prefer alternative to metal posts.
OBJECTIVE: To evaluate clinical effect and safety of MACRO-LOCK quartz fiber post restoration for residual root and crown.
METHODS: The patients with large-area anterior defect were randomly divided into 2 groups: quartz fiber post group: following complete root canal therapy, MACRO-LOCK quartz fiber post, ULPDENT resin adhesive, PULPDENT dual cure resin core material were used to restore tooth post and core, and then all-ceramic crowns or metal ceramic crown was applied; control group: cast metal teeth crown restoration was performed. The patients were followed up for 6 months and 3 years for observation of restoration effects.
RESULTS AND CONCLUSION: During the 3-year follow-up, there was 1 case of post and core loss, 1of broken fiber post, and no root fracture in the quartz fiber post group. The successful rate of the quartz fiber post group was higher than that of the control group during the 3-year follow-up (P < 0.05). The findings indicate that MACRO-LOCK quartz fiber post has a good long-term effect and safety to restore residual roots and crowns.
