MGBM system: new protocol for Class II non extraction treatment without cooperation

This article describes a method to treat Class II malocclusions with no patient cooperation. The technique involves converting the Class II molar relationship to a Class I in the initial phase of treatment by moving the maxillary molars distally with superelastic coils and wire. Anchorage is provided by a transpalatal bar attached to the first premolars and connected to 2 palatal miniscrews. Once the molars are positioned correctly, the palatal miniscrews are removed and miniscrews are inserted bilaterally in the buccal bone between the first molar and the second premolar. These miniscrews serve as the anchorage for the retraction of the premolars, canines and incisors.
