This article describes the orthodontic treatment of a 31-year-old Korean female patient with gummy smile and crowding. The patient showed excessive gingival display in both the anterior and posterior areas and a large difference in gingival heights between the anterior and posterior teeth in the maxilla. To correct the gummy smile, we elected to intrude the entire maxillary dentition instead of focusing only on the maxillary anterior teeth. Alignment and leveling were performed, and a midpalatal absolute anchorage system as well as a modified lingual arch was designed to achieve posterosuperior movement of the entire upper dentition. The active treatment period was 18 months. The gummy smile and crowding were corrected, and the results were stable at 21 months post-treatment.
本文描述了一名31岁韩国女性患者的正畸治疗过程,该患者存在露龈笑和牙列拥挤问题。患者在前牙区和后牙区均表现出牙龈过度暴露,上颌前后牙之间牙龈高度差异较大。为了矫正露龈笑,我们选择压低整个上颌牙列,而不是仅关注上颌前牙。进行了排齐整平,并设计了腭中缝绝对支抗系统以及改良舌弓,以实现整个上颌牙列的后上移动。积极治疗期为18个月。露龈笑和牙列拥挤得到了矫正,治疗后21个月结果稳定。
