Management of the Herbst splint appliance in Class II malocclusion with different growth pattern.

Class II malocclusion treatment can be successfully performed with the Herbst appliance stabilized with acrylic splints. Using this kind of stabilization a posterior open bite is always present when the appliance is removed. Two case reports are presented to illustrate how it is possible to manage the post- Herbst phase in different types of growth pattern in order to obtain the best aesthetical and functional results.
