Dentigerous cyst is the most common odontogenic cyst. It is characterized by a unilocular radiolucent lesion that encloses permanent tooth buds or, under certain circumstances, displaced tooth buds. Buccal bony expansion is the most common clinical feature. Several treatment modalities have been mentioned in the literature for management of dentigerous cysts. The purpose of this article was to report an extensive right mandibular dentigerous cyst on a 10-year-old boy. Marsupialization was chosen to preserve the permanent tooth bud and a denturelike obturator was then provided for space maintenance and masticatory function. Long-term follow-up revealed good healing of the bony lesion with converted tooth eruption.
含牙囊肿是最常见的牙源性囊肿。其特征为单房性透射性病变，包绕恒牙牙胚，或在某些情况下包绕移位的牙胚。颊侧骨质膨隆是最常见的临床特征。文献中提到了几种治疗含牙囊肿的方法。本文旨在报告一例10岁男孩的巨大右下颌含牙囊肿。选择袋形术以保留恒牙牙胚，然后制作类似义齿的阻塞器以维持间隙和咀嚼功能。长期随访显示骨病变愈合良好，牙齿顺利萌出。
