Abstract
Smile esthetics is a prime concern in contemporary orthodontic therapy. This case report is about a growing female patient with the inability to close the lips, vertical maxillary excess and hyperdivergent class II skeletal pattern. To enhance skeletal therapy benefits , differential intrusion of segments in the upper arch was required. Bilateral Bollard type miniplates were inserted on the infrazygomatic crest . The technique employed helped this patient avoid orthognathic surgery by allowing a complete upper arch intrusion, treating lip incompetence and causing counterclockwise movement of the mandible.
