Achievement of best balance and facial harmony is the main goal of orthodontic treatment, and it is especially important to retract the lip in case of maxillary protrusion. A 11-year and 7-months-old girl was first seen with chief complaints of maxillary protrusion. We extracted 4/4 4/4, treated the patients with the Vari-Simplex-Discipline for 43 months, and evaluated changes in facial profiles. We found, that excessive lip protrusion was eliminated and good interdigitation obtained. In addition to, angle ANB and overjet were corrected to ideal conditions.
实现最佳平衡和面部和谐是正畸治疗的主要目标，在上颌前突的情况下，唇部后缩尤为重要。一名11岁7个月大的女孩初诊时的主要诉求是上颌前突。我们拔除了4颗双尖牙，采用变异单丝矫治技术对患者进行了43个月的治疗，并评估了面部轮廓的变化。我们发现，过度突出的唇部得到了改善，实现了良好的牙合关系。此外，ANB角和覆盖也矫正到了理想状态。
