Management of occlusal canting with miniscrews

A 14-year-old boy with a skeletal Class II malocclusion and open bite whose chief complaint was a posterior crossbite showed a canted occlusal plane with asymmetric gummy smile and mandibular deviation at clinical examination. The treatment with miniscrews focused on the bilateral intrusion of the maxillary posterior teeth and, after resolving the open bite, a new biomechanical technique involving joined miniscrews was applied for an en masse intrusion of the left side. This treatment strategy achieved optimal occlusion with improvements to the sagittal, vertical, and transverse relationships and achieved a harmonious smile.
