摘要
复杂冠根折是一种涉及牙体硬组织、牙髓及牙周组织损伤的牙外伤,通常需要综合考量确定治疗方案,以期重建牙周组织健康,获得良好的预后。本文介绍了1例儿童恒中切牙复杂冠根折的序列治疗,通过改良冠延长术暴露牙根折断面,粘接断冠,完成根管治疗术并辅以纤维桩修复,最大限度地保留了患牙原本的牙周支持。经过2年随访,患牙重建了生物学宽度并形成生理性屏障,维持了良好的美学效果与牙周组织健康。
Complicated crown-root fracture involves enamel,dentin,pulp,cementum and periodontal tissue,which usually requires comprehensive consideration to determine the treatment plan,rebuild the health of periodontal tissue and retain a favorable long-term prognosis.This article presented the sequential treatment to a complicated crown-root fractured permanent central incisor in children,which included the exposure of the fracture margin by the modified crown lengthening,fragment reattachment,root canal treatment,and fiber post reinforcement.The modified crown lengthening surgery removed a small amount of bone tissue,which maximally preserved the original periodontal support of the affected tooth.After 2 years of follow-up,the biological width was reconstructed around the affected tooth,which maintained the desirable aesthetics and periodontal health.
