Changes from one year to 5 years after superior repositioning of the maxilla: a, the percentage of patients with changes in the vertical position of skeletal and dental landmarks; b, the percentage with changes in the vertical position of soft tissue landmarks. Although the long-term position of the maxilla is quite stable in 80% of the patients, 20% experience a downward movement, and when the downward movement occurs, parallel changes in the facial soft tissues occur.
