年轻恒前牙冠折断再接的临床观察

A Clinical Study of Reattachment of Fractured Young Permanent Anantierior Tooth Fragments

选择2006-02～2007-11来我院儿科就诊的32颗年轻恒前牙冠折的病例,采用日本可乐丽公司生产的帕娜碧亚F双固化粘接材料、3M纳米树脂、3M siglebond-2粘接剂进行自体断冠再接。通过半年至2年的观察,有2颗再接牙冠脱落,其余再接牙冠固位良好,形态美观。断冠再接术是一种简便的、适合于年轻恒前牙冠折的过渡性治疗方法。

This was a restrospective clinical study of 32 children with fractured anantierior tooth fragments.The teeth was reattached by dual cured resin composite（Panavia F）,3M Z350 resin and 3M siglebond-2 bonding agent for at least 6-month recall examination.Only 2 of the restorations were lost,resulting in a 93.75% overall retention rate.The retention teeth exhibited good esthetics and normal function.The high retention rate in this study suggests that reattachment of fractured anantierior tooth fragments offers a convenient viable restorative option for the clinician.
