The most obvious clinicians can do is to not handicap themselves by applying too many brackets in the beginning of therapy. Complete appliances places too many restrictions on the correction of Class II malocclusions and creates too many forces and moments that neutralize the efforts to put posterior teeth in a Class I occlusion. The achievement of a Class I platform should precede any effort to align and level the arches since once that is done, the completion of therapy becomes a routine and simplified mission. References Figure 22: Expansion and rotations of the maxillary molars can assist in the correction of Class II malocclusions.
that can cause temporomandibular fossae and dentoalveolar remodeling.5-7 He reveals this strategy with the following images of patient therapy (Figures 19-21). One final biomechanical feature clinicians should remember when treating Class II malocclusions is that merely widening the arch and rotating the maxillary molars can have a beneficial effect (Figure 22). Conclusion Class II malocclusions offer clinicians enormous challenges, which demand their best efforts to apply diagnosis, treatment planning and therapy in the most intelligent and effective manner. This demands a complete knowledge of the armamentarium available to the profession and also the knowledge that can simplify an otherwise complex task.
