활동이 많아진 현대 생활에서 악안면 부위 외상은다양하게 발생할 수 있다. 그 중 치아에 발생하는 손상은 법랑질의 불완전한 파절 또는 균열, 치수 노출 여부에 따라 달라지는 단순/복잡 치관 파절, 법랑질, 상아질과 백악질이 포함된 치관-치근 파절, 백악질과 상아질-치수가 포함된 치근 파절, 진탕, 아탈구, 측방탈구, 정출과 합입, 완전탈구 등을 포함하는 치아 탈구,그리고 중장기적으로 일어나는 치근 흡수 등으로 분류할 수 있다.
Completely avulsed tooth caused by a traumatic injury needs replantation for treatment choice. But, replantated tooth usually comes with inflammatory root resorption, replacement resorption and ankylosis, moreover ankylosis cause severe functional and esthetic problems. The outcome of replantated tooth depends on the following factors; minimal damage to pulp and periodontal tissue, the length of extraoral time, the medium of the tooth stored, the level of root formation and so on. The purpose of this case report is to describe the variable resorption pattern and to discuss types that influence the occurrence of resorption.
