Treatment of Class II division 1 malocclusion treatment with mandibular advancement features

March 02, 2020

Invisalign treatment with mandibular advancement is an efficient method for correcting Class II malocclusion in growing teens with patients reporting comfort and satisfaction during the treatment. This approach uses precision wings incorporated into the upper and lower aligners to engage the mandible in an advanced edge-to-edge position while the anterior teeth are being aligned. This reduces the use of interarch elastics, and differentiates the practice by offering another Class II solution besides wires/ brackets and functional appliances like the Herbst appliance. The simultaneous correction of the bite along with dental alignment results in greater efficiency compared to treating the bite relationship and the dental alignment sequentially.

Minimizing the use of elastics in Class II treatments not only addresses a patient compliance concern, it also addresses a treatment efficiency concern. The vertical force component of Class II elastics tends to extrude teeth, which redirects mandibular growth in a vertical direction and makes the A-P correction less efficient. Avoiding clockwise rotation of the mandible (i.e., downward and backward) helps to keep mandibular growth along a horizontal trajectory in order to maximize the sagittal change.
