The aim of this case study was to provide a detailed report of the orthodontic approach used in treating a Japanese patient with congenital hypoglossia.
The patient was a 6-year-old girl with hypoglossia, micrognathia, congenital absence of three incisors, and a telescopic occlusion accompanied by an extremely narrow lower arch. She had no limb anomalies, and her speech was normal.
Bite opening and mandibular widening from the early mixed dentition dramatically improved the extremely constricted mandible and telescopic occlusion. Cephalometric tracings taken from the beginning to the end of active treatment revealed substantial forward and downward growth in the mandible over time, which may have contributed to correction of the intermaxillary relationship.
Treatment of telescopic occlusion by bite opening and mandibular widening from the early mixed dentition may be effective in facilitating mandibular growth acceleration. An acceptable intermaxillary occlusal relationship and improvement of profile were achieved by an orthodontic approach in this case.
本病例研究旨在详细报告用于治疗一名患有先天性舌发育不全的日本患者的正畸方法。
该患者为一名6岁女孩，患有舌发育不全、小颌畸形、三颗门牙先天性缺失，以及伴有极窄下牙弓的套叠式咬合。她没有肢体异常，且言语正常。
从早期混合牙列期开始进行的开口咬合和下颌扩弓显著改善了极度狭窄的下颌骨和套叠式咬合。在积极治疗开始至结束期间进行的头影测量描记显示，随着时间推移，下颌骨有显著的向前和向下生长，这可能有助于矫正颌间关系。
从早期混合牙列期开始通过开口咬合和下颌扩弓治疗套叠式咬合，可能有效地促进下颌骨生长加速。在本病例中，通过正畸方法实现了可接受的颌间咬合关系和侧貌改善。
