Comments
- Buccally upright the crown of upper posterior teeth to help correct narrow upper dental arch
- Spaces gained from upper dental expansion and upper molars distalization combined with pre-treatment upper dental space and leeway space were used to help retract labially proclined upper incisors
- Class II elasctics were used for mandibular advancement and upper posterior teeth distalization
- Lower premolars extrusion and incisors intrusion to help correct severe anterior deep overbite
- IPR was used for upper anterior teeth to help correct Bolton discrepancy in the upper and lower anterior region
- Upper incisors retraction and mandibular advancement to help correct severe anterior deep overjet
- Power ridge designs were used for lower anterior teeth to help prevent gingival recession, alveolar bone dehiscence, and fenestration during orthodontic treatment
- Waited with 15, 25, 45, 17, 27, 37, and 47 until eruption into dentition and all could be included in orthodontic treatment
- Extraction of the supernumerary tooth after orthodontic treatment completed
