초록

하악 제1대구치의 맹출 장애는 매우 드물지만, 발생할 경우 교합 발육에 다양한 문제를 초래할 수 있으므로, 하악 제1대구치의 맹출 장애의 조기 진단과 치료는 매우 중요하다. 이번 연구의 목적은 맹출 장애를 가진 하악 제1대구치의 두 증례에 대한 치료 방법을 제시하는 것이다. 하악 제2유구치를 고정원으로 하는 cantilever-type의 spring을 추가한 견인 장치를 적용하여 매복된 제1대구치 견인을 시행했다. 따라서, 건전한 제2유구치가 존재하는 환자에서 이 장치가 짧은 시간 안에 매복된 하악 제1대구치의 정상적인 맹출을 유도할 수 있음을 확인 할 수 있었다.

Eruption disturbances of the mandibular first molars can cause multiple problems in occlusal development although they are extremely rare. Early diagnosis and treatment are very important to prevent complications associated with eruption disturbances. The present case report describes the treatment of two cases of eruption disturbances of the mandibular first permanent molar. A fixed appliance composed of a cantilever spring with mandibular second deciduous molar as an anchor tooth was used to tract the impacted mandibular first permanent molar. The success of both cases shows that this novel traction appliance can be used to induce the eruption of an impacted mandibular first permanent molar within a short time in patients with intact mandibular second deciduous molar as an anchor tooth.
