A 40-year-old black woman, with pretorqued, preangulated appliances on the maxillary teeth, transferred with chief concerns of missing teeth and her orthodontic progress. She had bialveolar protrusion and edentulous areas in both the maxilla and the mandible. After records were made and her desires assessed, she was retreated with the extraction of 3 premolars. Her protrusion was reduced and all edentulous spaces were closed. The facial change was evident due to the reduction of the protrusion.
一位 40 岁的黑人女性，上颌牙齿装有预扭转、预成角的矫治器，主要关注缺牙和正畸进展。她存在双牙槽前突，上颌和下颌均有缺牙区。在记录并评估她的需求后，我们为她进行了 3 个前磨牙的拔除。她的前突得到了改善，所有的缺牙间隙都关闭了。由于前突的减少，她的面型变化很明显。
