Abstract
Deep bite is due to various dental and skeletal etiologies. The treatment of deep bite includes growth modification, orthodontic treatment (intrusion of the anterior teeth or extrusion of the posterior teeth or combination of the two) and orthognathic surgery. During treatment planning, the orthodontists should consider patient’s growth potential, skeletal
pattern, vertical positions of the maxillary incisors relative to the upper lip, occlusal plane, and gummy smile, etc. In
the case of Class II patient with mandible deficiency, counterclockwise rotation of the mandible by intrusion of the
posterior teeth could improve the facial profile. However, in a Class II deep bite patient, the counterclockwise rotation
of the mandible could worsen the deep bite. This clinical case report presents the vertical control of a Class II deep
bite malocclusion by distalization of the whole maxillary dentition and intrusion of the anterior teeth using orthodontic
mini-implants (OMIs).
