The use of the headgear appliance for the treatment of Angle Class II malocclusion demands that the biomechanic principles are understood and applied so that the clinic case is conducted in a way that the side effects are minimized and the benefits maximized. Therefore, the orthodontist must be able to predict the effects of the inclination of the line of traction and its relation to the teeth and maxillary centers of resistance. Any rotation movement, inclination or translation of the teeth and maxillary and mandibular rotation clockwise or counter clockwise can be predict and planned when the orthodontist knows the mechanism that cause them, as well as the effects that the different types of traction produce in subjects with dolichofacial, mesofacial or brachyfacial types. Thus, the aim of this work is to present predominant and indispensable factors for the utilization of the headgear appliance for the treatment of Angle Class II malocclusion.
