Monoblock appliances were used in combination with intermaxillary elastics for treatment of adult skeletal Class III patients. The patients showed predisposing upper incisors problems, significant mobility in patient 1 and root resorption in patient 2, which contraindicated direct intrusion of the incisors. Using the monoblock with selective extrusion of the molars, a clockwise rotation was induced to reduce overbite and to achieve a better profile. It was also possible to reduce the excessive force to the upper incisors during and after treatment, which improved incisor mobility to a physiologic extent (patient 1) and prevented further progression of root resorption (patient 2). Stability was high after the 2-year follow-up, which suggests a stable vertical control approach by using the monoblock appliance in combination with a fixed appliance in adults.
