摘要
目的观察用螺纹桩横向牵拉、固定恒磨牙斜向裂开的治疗效果,为临床保留劈裂牙提供一种实用的方法。方法回顾性分析2010年1月——2011年12月天津市第一中心医院口腔科应用螺纹桩横向牵拉、固定修复恒磨牙斜向裂开50例患者的临床资料,采用患牙于牙颈部钢丝捆绑、结扎、固定劈裂牙,并均行完善根管治疗,沿颊-舌/腭横向钻孔置入螺纹桩配合流体光固化复合树脂粘结固定冠劈裂牙,封闭缝隙以避免劈裂两端相对移位,行牙冠保护性修复(全冠)。术后随访10~60个月,观察患者治疗效果。结果 50例患者5年内完全治愈41例,临床治愈6例,治疗失败3例。结论螺纹桩横向牵拉、固定冠斜裂恒牙具有较好的修复效果,可达到保留患牙并行使咀嚼功能的目的,避免或减少拔除患牙。
Objective To explore the effect of preservation of inclined fractured permanent molars by transverse fixation with screw post,and provide a practical method for reserving the inclined fractured permanent molars.Methods Clinical data of50patients with inclined fractured permanent molars by transverse fixation with screw post in the Department of Stomatology of Tianjin First Central Hospital between January2010to December2011were reviewed retrospectively.After fixing the crown with steel-wire binding and root canal treatment,the molars were drilled a hole buccolingually and placed screw post.The flowable light-curing composite resin was used to seal the crack and bond screw post to prevent the relative movement.All treated molars were restored with full crown.All patients were followed up for10-60months.The therapeutic effects were observed.Results After5year-follow-up,41cases were cured completely,6cases were cured clinically,and3cases failed treatment.Conclusion The transverse fixation with screw post and bonding technique can preserve the inclined fractured molars to gain chewing function and avoid or reduce the extraction of affected teeth,which provides a better restoration effect.
