An 8-mm anterior and posterior open bite caused by a tongue rest posture habit was closed in a 25-year-old man by means of mandibular soldered tongue spurs and without orthognathic surgery. All maxillary and mandibular first molars were extracted, and the spaces were closed. Inappropriate retention protocol allowed for relapse in a 6-month period. A new 1-year orthodontic retreatment was conducted; after an appropriate retention protocol, the outcomes of treatment were significantly improved.
一名 25 岁男性因舌挡姿势习惯导致 8mm 的前牙及后牙开合，通过下颌焊接舌刺而非正颌手术关闭。所有上颌及下颌第一磨牙均被拔除，间隙关闭。不合适的保持方案导致 6 个月时复发。进行了新的 1 年正畸治疗，在适当的保持方案后，治疗效果显著改善。
