법랑모세포종은 구강악안면영역에서 발생되는 낭종 및 종양의 약 1%를 차지하고, 치성종양 중 10% 정도에 해 당하는 비교적 흔한 양성 치성종양으로 이들 중 2%이상 은 악성으로 변위된다고 보고되고 있다1). 법랑모세포종 은 하악골에 80%, 상악골에 20%정도 나타나며 하악에 서는 주로 제3대구치와 하악지 사이에서 호발한다2). 조 직학적으로 양성이고 성장 속도도 느리지만, 침윤적으로 성장하기 때문에 재발이 잘 되고 또한 특별한 자각증상 없이 상당한 크기로 성장함으로써 악골 피질골의 팽창 또는 파괴를 야기시켜 안모의 심미적 결손과 저작의 기 능적 부전을 초래하게 되는 경우도 많다3).
Ameloblastoma is a rare histologic benign tumor which accounts for 1% of all oral tumors and for 9% to 11% of all odontogenic tumors, but locally aggressive tumor with a marked tendency for recurrence. Two therapy strategies are mentioned in literatures: a conservative way of treatment and radical procedures. Conservative surgical procedures like marsupialization, enucleation, and curettage, or just drilling of the perilesional bone are mentioned to be useful in unicystic ameloblastoma, especially in children and young patients. But, many recent reports have warned of high recurrence rates(75~90%) with conservative treatment, compared with recurrence rates of 15~20% after radical surgery. So other authors show high rates of recurrence of ameloblastoma after conservative treatment protocols and therefore recommend radical surgical treatment. However, mandibular resection can also lead to mastication, deglutition, phonation, and esthetic problem and require reconstruction of complex jaw defects. We experienced three patients who had mandibular ameloblastoma treated with radical resection and immediate reconstruction using iliac bone graft, and then implant-supported prosthesis. So, we report cases with a review of the literatures. [THE JOURNAL OF THE KOREAN ACADEMY OF IMPLANT DENTISTRY 2009;28(2):52-59]
