Vertical control of a Class II deep bite malocclusion with the use of orthodontic mini-implants

To improve the facial profile of a Class II patient with chin deficiency, orthodontists have traditionally used incisor retraction or jaw surgery. Recently, a new technique was introduced that uses orthodontic mini-implants to intrude the incisors and rotate the mandibular plane counterclockwise. In patients with deep bite, heavy anterior occlusal contact can make it difficult to use intrusion for profile improvement. This case report shows the successful treatment of a patient with Class II deep bite and chin deficiency by means of intrusion of the maxillary and mandibular dentition with multiple orthodontic mini-implants.
