Comments
Severe overjet was improved by distalization of posterior teeth and IPR in conjunction with Class II elastics.
Leveling of lower curve of Spee was performed by intrusion of lower incisors and extrusion of L456.
Proclination of upper incisors was significantly reduced by retraction of those teeth.
She was very satisfied with her smile and final outcome.
