Case report RS: guided tissue regeneration precedes tooth movement and crossbite correction

This patient presented with a Class III malocclusion and an anterior crossbite. Although spaces were present distal to the mandibular canines, the alveolar ridges were greatly atrophied. New bone was acquired through guided tissue regeneration. The alveolar ridges were augmented, followed by successful orthodontic tooth movement and correction of the Class III relationship and the anterior crossbite.
