To show with this case report that lingual orthodontics can be a solution in complex adult situation and with interdisciplinary approach.
The patient presented a dental and skeletal high angle class II division 1 with a previous extraction of one mandibular incisor. The strategy of treatment was upper first premolar-extraction to obtain a correction of the incisal-class II relationship with a normal lip function, a class II molar relationship on the right side and a class I on the left side. A lingual appliance and miniscrews were used.
The lingual orthodontic treatment with miniscrews responded to the occlusal objectives with a good upper incisors torque and retraction control.
Limits and advantages of lingual orthodontics were discussed.
Lingual mechanics can provide good results from both an aesthetic and function point of view in adult complex extractions case. It ensures aesthetics during treatment, incisor control during retraction. Miniscrews were also useful to overcome the periodontal limits and enhance the anchorage.
通过本病例报告表明，舌侧正畸可以作为一种解决方案，应用于复杂的成人情况，并采用多学科方法。
患者表现为牙性和骨性高角Ⅱ类 1 分类，曾拔除下颌切牙 1 颗。治疗策略为上颌第一前磨牙拔除，以获得正常唇功能下切牙Ⅱ类关系的矫正、右侧磨牙Ⅱ类关系和左侧磨牙Ⅰ类关系。使用舌侧矫治器和微螺钉。
带微螺钉的舌侧正畸治疗达到了咬合目标，实现了上切牙转矩和内收控制良好。
讨论了舌侧正畸的局限性和优势。
在成人复杂拔牙病例中，舌侧力学从美观和功能角度都能提供良好的效果。它确保了治疗过程中的美观，以及内收过程中切牙的控制。微螺钉也有助于克服牙周限制并增强支抗。
