摘要

上颌门牙显示不佳会对面部美观产生负面影响。根据潜在的病因和病情的严重程度,存在各种治疗方案。采用骨支抗挤压上颌牙列,使下颌骨向后旋转,提高上颌门牙的可见性。介绍了一种实现正畸挤压的挤压组件。还讨论了咬合提升器和弓间弹性材料的使用。治疗结果表明治疗目标已成功实现。除了最佳咬合外,患者的面部轮廓也随着嘴唇丰满度的增加而改善。面部垂直高度增加,上颌门牙显示明显改善,笑容更加愉快。两年的牵张记录证明了全弓挤压改善上颌切牙显示的稳定性。

Total arch extrusion with skeletal anchorage to improve inadequate maxillary incisor display in a case of vertical maxillary deficiency.

Inadequate maxillary incisor display can negatively impact facial esthetics. Various treatment options exist depending on the underlying cause and severity of the condition. Skeletal anchorage was used to extrude the maxillary dentition and rotate the mandible backward, enhancing visibility of the maxillary incisors. An extrusion assembly was introduced to achieve orthodontic extrusion. Use of bite raisers and interarch elastics was also discussed. Treatment results demonstrated successful achievement of the treatment goals. In addition to optimal occlusion, the patient's facial profile improved with increased lip fullness. There was an increase in vertical facial height, and maxillary incisor display was significantly improved, resulting in a more pleasant smile. Two-year postretention records evidenced the stability of total arch extrusion to improve maxillary incisor display.
