Early treatment with the Twin-block appliance is effective in reducing overjet and severity of malocclusion in Class II division 1 malocclusions with functional mandibular retrusion. Appearance of bilateral severe posterior open bite in some cases subsequent to completion of active phase of Twin block therapy poses a challenge to an orthodontist. Closure of posterior open bites of large magnitude is difficult to achieve with conventional upper anterior inclined plane used during support phase of Twin-block therapy. A simple yet effective modification of upper anterior inclined plane is proposed, which is an effective and invaluable adjunctive aid in correction of posterior open bite.
