초록

저위교합(infraocclusion)은 혼합치열기에 유구치에서 호발하며, 이것은 대부분 이환된 치아의 유착에 의해서 발생하는 것으로 여겨지고 있다. 유착된 저위교합 유구치의 치료 방법은 크게 치아의 보존 및 관찰, 수복, 발거로 나눌 수 있다. 계승치가 존재하고 경도의 저위교합을 가진 유구치의 경우 자연탈락을 기대할 수 있으나, 계승치가 결손되어 있고 저위교합도 점차 진행될 경우 이환된 치아의 발거가 필요할 수 있다. 특히 유착으로 인한 수직적인 치조골 소실이 염려될 경우, 추후 보철치료를 위해 환아의 최대성장기 이전에 유착치의 발거를 시행하여야 한다. 본 증례에서는 만 6세의 다발성 유착 유구치 및 저위교합과 계승치 결손을 보이는 환자에서 인접부의 성장에 따른 치조골의 수직적 결손이 심화되는 것을 막고 정상적인 치조골 성장을 도모하기 위해 최대성장기 이전에 유착치를 발거 후, 장기간에 걸쳐 추적 관찰하였기에 보고하는 바이다.

The infraocclusion usually occurs in the mixed-dentition stage, and it is commonly accepted that the cause of the infraocclusion is ankylosis. The treatment options for patient with infraocclusion of primary molars are observation, restoration or surgical removal of the affected teeth. If the successors are present, most of the infraoccluded and ankylosed primary molars may occur normally. However, when the permanent successors are absent and the progression of infraocclusion is found, affected teeth may need to be extracted. In the case of infraocclusion which can cause vertical alveolar defect due to ankylosis, extraction before growth spurt should be performed for the future prosthetic treatment. A six-year-old female had the ankylosis and infraocclusion of multiple primary molars and congenital missing of premolars. The affected primary molars were extracted before growth spurt to avoid a significant vertical ridge defect and to promote the vertical development of alveolar bone, and the result was observed for many years. The purpose of this report is to report the management of multiple infraoccluded primary molars without permanent successors in a young patient.
