Doctor's summary
1. Generally, good invisible orthodontic treatment results are obtained for most cases of spaced teeth without deep bite.
2. As patients have bad habits of swallowing and tongue thrust, it is especially important to help patients break bad habits. Only by breaking bad habits can the recurrence risk of open bite and spaced teeth be reduced.
3.As the patient disapproved of tooth extraction, the convex profile was not corrected obviously.
4. At the end of treatment, posterior occlusion of the patient was not tight. Triangular traction was recommended. The patient felt that eating did not affect refusal of traction. After wearing the retainer from day to night for half a year, the patient only wore the retainer at night, which had been retained for 1 year, afterwards, examination showed improved occlusion.
