Abstract

In the management of ankylosed primary molars, early diagnosis, proper treatment, and thorough follow-ups are very important. Untreated infraocclusion due to ankylosis has a negative impact on normal occlusal development, and may cause problems. There are many treatment options on infraoccluded deciduous molars, such as periodic observation, conservative method, restoration, and space regaining via extraction of the teeth. In this case report, two 6-year-old girls were diagnosed with ankylosed maxillary second primary molar and displaced tooth germ of the second premolar. Early surgical removal of the ankylosed primary molar was considered as a treatment approach. The long-term follow-up shows normal eruption of a succeeded permanent premolar.

유착된 유구치의 치료에 있어 조기 진단이 매우 중요하다. 유착으로 인하여 발생된 저위교합을 방치하는 경우 교합적인 문제가 생길 수 있으므로 정기검진을 통한 진단과 이에 따른 적절한 치료가 필요하다. 저위교합 된 유구치의 치료 방법으로 정기검진, 보존적 접근, 보철적 수복, 발치를 수반한 공간획득 등이 있다. 본 증례에서는 상악 제2유구치의 유착으로 인하여 제2소구치 치배의 변위를 보이는 두 명의 환아를 대상으로 이환치의 발거를 먼저 시행하고 고정성 혹은 가철성 교정장치를 이용하여 공간확장술을 함으로써 변위 되었던 제2소구치 치배의 정상 맹출을 유도하였으며 장기간에 걸쳐 부작용이 없었음을 보고하는 바이다.
