Which of the following headgear is preferred while treating a class II div. 1 malocclusion with a horizontal growth trend?
(A) High pull head gear (B) Medium pull head gear (C) Cervical head gear (D) Reverse pull head gear
(C) Cervical headgears cause extrusion of maxillary molars and thus increase the lower facial height. So these are generally indicated in low mandibular angle cases (horizontal growers) as an increase in lower facial height would be beneficial in these patients.
