Aim
To present the treatment and long-term post-treatment results of an adult case presenting with an Angle Class II anterior openbite malocclusion that involved the use of zygomatic anchorage for the intrusion of the maxillary posterior teeth.
Methods
A 23-year-old female patient with a bilateral Angle Class II molar and canine relationship, a 4 mm overjet and a 6 mm anterior open-bite was treated using zygomatic anchorage in order to correct the dental and skeletal relationships, and eliminate the anterior open-bite to achieve an ideal overjet, overbite and improved facial aesthetics. Orthodontic brackets were placed on the maxillary and mandibular teeth. Under local anaesthesia, a subperiosteal flap was raised, and two titanium miniplates were bilaterally placed in the zygomatic area. The molars were intruded by applying 400 grams of force to the miniplates via connection to the upper arch wire.
Results
By intruding the molar teeth using zygomatic anchorage, the anterior open-bite was corrected to achieve an Angle Class I occlusion, an ideal overbite and a harmonious facial profile that were successfully maintained after a 10-year follow-up period.
