Lingual orthodontic treatment of a skeletal class II patient with miniscrew-assisted absolute anchorage in maxillary arch and total distalization in mandibular arch: a case report.

Purpose: This case report describes the lingual orthodontic treatment of an adult skeletal Class II division 1 patient with lip protrusion, mandibular retrusion, severe overjet and deep overbite, proclined upper and lower incisors and mild crowding in both arches. Materials and methods: The overjet was corrected with upper first premolar extraction with the help of skeletal absolute anchorage. Also, 4 third molars were extracted and miniscrew-assisted total distalization was performed in mandibular arch to decrease the proclination of lower incisors after aligning and levelling. Results: After 25-month treatment, satisfactory facial aesthetics and good occlusion were achieved. A two-year follow-up after confirmed that the outcome was stable. Conclusion: Maxillary first premolar extraction combined with total arch distalization with skeletal anchorage could greatly reduce the excessive overjet and lip protrusion in skeletal Class II cases.
