Skeletal changes produced by cervical and parietal headgears: a cephalometric evaluation

Abstract Introduction Extraoral strength is the most common strategy to correct Angle Class II malocclusion, restricting and redirecting maxillary growth. Objective To evaluate skeletal changes resulting from use of headgear, with cervical parietal anchorages, associated a full fixed orthodontic appliance, in growing patients malocclusion (Angle) treated clinic an training center. Material method The ages at beginning end treatment, anchorage type, values some cephalometric variables were obtained clinical files. After applying inclusion exclusion criteria, 56 patient files selected. Then, sample was divided into two groups, according type: (n=30) (n=26). differences between initial (T1) final (T2) measurements SNA, SNB, ANB, AO-BO, GoGn.SN LHF (percentage lower facial height total height) evaluated both groups. Result Significant T1 T2 found relative SNB ANB AO-BO variable presented statistically significant difference only group. remaining did not show T2. Conclusion or very similar. There decrease sagittal discrepancy bones due forward displacement mandible, without vertical changes.
