Class II division 1, orthosurgery
Comprehensive treatment with fixed appliances in both arches in a patient of 55 years and 5 months of age. To obtain dental symmetry and to fix the residual crowding, we extracted 2 teeth. A bilateral sagittal split osteotomy for mandibular advancement surgery allowed the correction of the anterior-posterior discrepancy between the upper and lower teeth.
This patient’s testimony is posted at this link (in French).
Class I, lack of space and anterior crossbite
Class I, anterior and posterior crossbite on the left side. Congenital absence of the lower right second premolar. Retention of the lower right primary second molar.
The treatment included a rapid palatal expansion phase, the extraction of the upper right second premolar, of the upper left first premolar and of the lower right primary second molar. There were no extractions of premolars on the lower left side.
