摘要:

牙齿折断性损伤分为:冠折、根折和冠根折。冠折时建议采用断冠粘接,较年轻恒牙建议应用盖髓术或部分牙髓切断术以保持牙髓活性;根折时,建议尽早复位;冠根折时建议采取急诊处置,临时粘接断冠。在根中1/3根折、根颈1/3根折和冠根折时,序列治疗有助于保存断冠。

Abstract:

Teeth fractures include crown fracture, root fracture and crown-root fracture. If the tooth fragment is available, it can be bonded to the tooth. In young patients with immature, still developing teeth, it is advantageous to preserve pulp vitality by pulp capping or partial pulpotomy. Also, this treatment is the choice in young patients with completely formed teeth. If displaced, reposition the coronal segment of the tooth as soon as possible. As an emergency treatment a temporary stabilization of the loose segment to adjacent teeth can be performed. Sequential therapy for traumatized teeth with mid-root fracture or cervical third fracture or crown-root fracture could preserve the coronal fragment.

Key words: fractures of teeth, reposition, sequential therapy
