Long-term stability of surgical-orthodontic correction of class III malocclusions with long-face syndrome

2011

Objectives: In the first place, to evaluate skeletal changes of the maxilla and mandible induced by surgical-orthodontic correction of malocclusions class III with long-face syndrome and secondly, to analyze the stability of these skeletal changes in the long term (more than 6 years).
