摘要
复杂冠根折是牙外伤中一类累及牙髓的釉质-牙本质-牙骨质联合折断,治疗方法复杂,过程中需综合考虑牙髓、牙周及牙体情况,进行多学科联合序列治疗.本病例报道了1例上前牙复杂冠根折后2颗患牙不同的治疗修复过程,包括初诊时翻瓣术后11牙的断冠再接和21牙腭侧去除断裂碎片直接树脂修复,以及复诊时11、21牙的牙髓治疗及冠部修复,经过18个月的随访,患牙的功能及牙周状况维持良好,美观性也得到了患儿及家长的肯定.对于儿童复杂冠根折上前牙,断冠再接及桩冠修复是一种可行的治疗方案.
Abstract
Complicated crown root fracture is a serious combined fracture of the enamel,dentin,and cementum in dental trauma.The treatment method is complicated.During the procedure,the condition of pulp,periodontal,and tooth body should be thoroughly evaluated,and a multidisciplinary approach combined with sequential treatment is recom-mended.This case reported the different treatment and repair processes of one case of two affected teeth after complicat-ed crown root fracture of upper anterior teeth,including regrafting of broken crown after flap surgery at the first visit,di-rect resin repair to remove broken fragments,and pulp treatment and post-crown repair at the second visit.After 18 months of follow-up,the preservation treatment of the affected teeth with complicated crown root fracture was achieved.Therefore,fragment reattachment and post-crown restoration are feasible treatment options for children with complicated crown root fracture.
