To report the treatment of a severe Class II division 1 malocclusion using bone-plate anchorage.
A 12 year-old Thai girl presented with a skeletal 2, Class II division 1 malocclusion. Following extraction of the maxillary first premolars and mandibular second premolars, the maxillary anterior teeth were retracted and the mandibular posterior teeth moved mesially. A miniplate with screws, placed in each zygomatic buttress, was used as absolute anchorage for coil springs to retract the maxillary anterior six teeth.
After treatment, the patient presented with a normal overjet and overbite, a dental Class I relationship bilaterally and an improved facial profile.
