Abstract

One of the common complications of dental injury is tooth ankylosis. Unlike adults, when tooth ankylosis occurs in the adolescents, ankylosis interfered the growth of the adjacent alveolar bone, resulting in the developmental failure of the alveolar bone and subsequent open bite. The most common treatment option for ankylosed tooth is extraction. However, when prognosis of ankylosed tooth after extraction is expected to be poor due to severity of infrapositioning or prosthetic replacement cannot be performed immediately, various treatment options should be considered. This report suggests multidisciplinary treatment that might bring functionally and esthetically favorable result included alveolar bone distraction osteogenesis and decoronation of ankylosed maxillary anterior tooth with orthodontic and prosthetic treatments.

치아 외상에 따른 흔한 합병증 중 하나는 치아 유착이다. 성인과 달리 성장기 아동에서 유착이 나타날 경우 유착치가 인접 치조골의 성장을 방해하여 치조골의 발육 부전과 이에 따른 개방 교합을 야기한다. 그러나 저위된 유착치를 단순 발치할 경우, 성장 완료 시까지 치조제의 상당한 소실을 유발하여 향후 심미적인 보철물을 수복하기가 어려워진다. 본 증례에서는 성장기에 상악 전치의 유착이 발생한 환자에서 단일 치아 골절단술 후 치조골 신장술과 치관 절제술을 시행하여 상악 전치부의 유착치를 심미적으로 결과를 얻었으므로 소개하고자 한다.
