Abstract

Orthodontic problems of the oral maxillofacial area could be classified into skeletal and dental problems. Dental problems might cause various occlusal disharmony and among them congenital missing or eruption failure might cause not only functional problems but also esthetic problems. Additional psychological problems are also one of the reasons for patients seeking treatment. In cases showing eruption failure of many teeth in the maxilla, not only occlusal and esthetic problems but also difficulty in alveolar bone maintainment could occur. Therefore, successive approach is necessary when multiple teeth show eruption problems. In this case, a patient with eruption problems of #13, 12, 11, 23, 43 was successfully treated by surgical exposure and successive orthodontic extrusion resulting perfect occlusion. By additional periodontal treatment, gingival recession that occurred along with teeth eruption was solved. The impacted right mandibular canine was erupted successfully only by natural arch expansion and leeway space without any special surgical treatment.

악악면 부위의 교정적 문제는 크게 골격적인 문제와 치성적 문제로 나룰 수 있다. 치성적 문제로 인해서 많은 교합의 부조화가 발생하는데 이중 치아의 결손 또는 치아의 맹출 실패는 기능적 문제뿐만이 아니라 심미적 문제도 같이 유발한다. 또한 추가적으로 발생하는 심리적인 문제도 환자를 내원하게 만드는 중요한 이유이다. 상악골에 다수의 치아가 맹출 하지 못하는 경우에는 교합적, 심미적 문제 뿐만 아니라 치조골의 유지 또한 어렵게 하는 문제가 발생한다. 따라서 다수치의 맹출에 문제가 있는 경우에는 보다 단계적 접근이 필요하다. 본 증례의 환자는 #13, 12, 11, 23, 43이 맹출하지 못하는 문제를 주소로 내원하였으며, 상악 치아들을 맹출하게 하기위한 외과적 노출술 및 단계별 교정적 정출을 통하여 완벽한 교합을 이룰 수 있었다. 또한 추가적인 치주 처치를 통하여 치아맹출시 발생한 치은 퇴축을 제거하였다. 우측 매복 하악 견치는 자연스러운 악궁 확장과 leeway space를 이용하여 특별한 외과적 처치 없이 성공적으로 이루어졌다.
