Abstract：
BACKGROUND: Up to 25% of the tooth extraction after root canal treatment could be attributed to the vertical root fracture (VRF). The treatment choice for teeth with VRF would mostly be the extraction despite some repairing methods were also reported. The repairing treatment result of VRF would mostly depend on the fixation strength and the bioactivity of the repairing materials, especially for the posterior teeth with high masticating stresses. This case report designed a novel surgical treatment approach for the VRF of posterior teeth.
METHODS: a maxillary premolar with buccal-palatal complete VRF was treated with a new dual-layered repairing approach using adhesive resin + iRoot BP Plus bioceramic cement to fill the modified fracture line with retention forms through the intentional replantation.
RESULTS: At the 24-month review, the tooth showed desirable periodontal healing and normal function.
CONCLUSIONS: This case report indicated that the dual-layered repairing approach might be effective for saving the posterior teeth with VRF. Nevertheless, further clinical trials are needed for its long-term result.

摘要：
背景：根管治疗后拔牙的25％可归因于垂直牙根骨折（VRF）。尽管也报道了一些修复方法，但VRF牙齿的治疗选择主要是拔除。VRF的修复效果主要取决于修复材料的固定强度和生物活性。特别是对于咀嚼应力高的后牙。该病例报告为后牙VRF设计了一种新颖的手术治疗方法。
方法：采用新的双层修复方法，使用粘合剂树脂iRootBPPlus生物陶瓷水泥，以保留形式填充改良的骨折线。有意再植。
结果：在24个月的审查中，牙齿显示出理想的牙周愈合和正常功能。
结论：该病例报告表明，双层修复方法可能对保留VRF后牙有效。然而，其长期结果还需要进一步的临床试验.
