Nonmineralized cysts and cyst-like lesions that frequently occur in the mandible include ameloblastomas, odontogenic keratocysts, and dentigerous cysts. They have specific features of well-demarcated, unilocular, and radiolucent lesions that are often associated with tooth impaction. Although it rarely occurs, these cysts can become extremely large. Furthermore, cyst enlargement causes additional symptoms that can challenge the success of tooth recovery through orthodontic treatment. This clinical report presents the successful eruption of 2 impacted molars in a large dentigerous cyst treated with marsupialization and orthodontic traction using an orthodontic miniplate anchorage over a 4-year treatment period.
下颌骨中经常发生的非矿化性囊肿和囊状病变包括造釉细胞瘤、牙源性角化囊肿和含牙囊肿。它们具有界限清楚、单房性和透光性病变的特定特征，常与牙齿阻生有关。尽管这种情况很少发生，但这些囊肿可能会变得非常大。此外，囊肿增大还会引起其他症状，这可能会影响正畸治疗恢复牙齿的成功。本临床报告介绍了在 4 年的治疗期间，通过使用正畸微型板锚固进行袋形手术和正畸牵引，成功萌出 2 颗受含牙囊肿影响的阻生磨牙。
