Abstract: Dentigerous cyst is one of the common cystic lesions of the jaw bone，which is usually accompanied by impacted teeth. Although the traditional surgical removal method（enucleation）can eradicate the lesion，it is very likely to cause dentition defect，nerve injury，adjacent tooth injury or loss of dental pulp vitality. At present，more and more scholars advocate the use of marsupialization to reduce the injury of adjacent structures and preserve the intracyctic embedded teeth，and satisfactory results have been achieved by marsupialization combined with orthodontic traction to promote the eruption of cyst-associated teeth if they are deeply impacted. The article briefly introduces the formation of dentigerous cysts，indications for marsupialization and orthodontic traction for impacted teeth within cyst.

Key words: dentigerous cyst, marsupialization, orthodontic treatment

摘要： 含牙囊肿是口腔内常见的颌骨囊性病变之一，通常伴有阻生牙。刮除术虽能根除病变，但易造成牙列缺损、神经损伤、邻牙损伤或牙髓活力丧失等。近年来临床上常用的袋形术，可减少邻近结构的创伤及提高囊内阻生牙的存留率，对于位置深或无法自行萌出的阻生牙配合正畸牵引可取得满意的效果。文章简要介绍含牙囊肿的形成、袋形术的适应证以及囊肿内阻生牙的正畸牵引等临床问题。
