Long-term orthodontic treatment and observation have been required often for the patients with anterior crossbite associated with the unexpected growth of the maxilla and mandible. For these patients, two-stage orthodontic treatment has been routinely performed, the treatment of the mixed dentition for the first stage procedure and the treatment after the puberal growth spurt for the second stage procedure. The result and the stability of the first stage treatment affect the difficulties and duration of the second stage treatment.
In this report, we have treated a skeletal class 3 patient with anterior crossbite and crowding, impacting the canine and morphological anomalies of the teeth for 14 years and 6 months. The active orthodontic treatment was initiated at 8 years 8 months of age.
From this treatment, we experienced unpredictable manners of the mandibular growth and development during the post-puberal period. This treatment suggests that to be succeeding the skeletal class 3 treatment need the patient's cooperation and the management of occlusion during post-puberal period at the long-term orthodontic treatment.
