摘要： 根管治疗后牙根抗折性下降,受外力作用易导致折裂,被称为继发性牙根纵裂(secondary vertical root fracture,SVRF)。本文报道截根术联合引导性组织再生术(guided tissue regeneration, GTR) 治疗上颌第一磨牙继发性纵折1例。随访1年显示,截根部位实现了良好的骨组织再生。

Abstract: The fracture resistance of endodontically treated roots is compromised, rendering them susceptible to fracture when subjected to occlusal forces. This condition is termed secondary vertical root fracture (SVRF). The management of SVRF in a maxillary first molar using root resection combined with guided tissue regeneration (GTR) is reported. One-year follow-up showed good bone tissue regeneration at the root resection site.

Key words: secondary vertical root fracture, root resection, guided tissue regeneration
