코멘트
- This is a Class I bi-maxillary protrusion case with crossbite
- The patients chief request was to profile improvement
- The treatment plan is U4L5 extraction and space closure using maximal anchorage
- Torque loss of incisors and bite deepening are the main problem during this kind of treatment
- In this case, we control anterior torque with power ridges and control the bite with precision bite ramp
- Patient changed her aligner every 7 days with very good compliance
