Case 1-2
Overview
A 34-year, 9-month-old man presented with a severe highangle open bite with extreme crowding in the mandibular arch (Figs 1-7a to 1-7j). It was initially apparent that in addition to extraction of the premolars to align the arches, the skeletal problem would require maxillofacial surgery.
Examination and diagnosis
In addition to the vertical skeletal pattern and open bite, the mandibular arch had an extreme arch length discrepancy (more than 8 mm). This discrepancy would necessitate extraction regardless of the final treatment plan. To add to the complications, the molar relationships were Class I on the right side and Class II on the left side. Because of the severe open bite, when the patient smiled, only one-half of the clinical crowns was exposed.
Treatment plan
The decision was made to treat the patient surgically СКАЧАТЬ
