de Siqueira V.C.V.
|Abstract:||Objective: This study investigated vertical control and the effects of orthodontic treatment on dolicofacial patients, using cervical headgear (CHG) and lower utility arch. Methods: Cephalometric assessment of 26 dolicofacial patients with Class II, division 1, and mean age of 114 months. Orthodontic treatment involved the use of cervical headgear (CHG) in the maxillary arch, lower utility arch in the mandibular arch until normal occlusion of the molars was obtained and finished in accordance with Bioprogressive Therapy, with a mean duration of 56 months. The values of FMA, SN.GoGn, ANB, Fg-S, S-FPm, maxillary length, mandibular length, posterior facial height (PFH), anterior facial height (AFH), facial height index (FHI), occlusal plane angle (OPA), palatal plane angle (PPA), total chin (TC), upper lip (UL) and Z angle were evaluated. Results: The results showed that treatment promoted stability of the mandibular, occlusal and palatal planes. Anteroposterior correction of the apical bases occurred, verified by the significant reduction in the variable ANB. The maxilla presented slight anterior displacement and increase in the anteroposterior dimension. The mandible presented improvement in its position in relation to the cranial base and its anteroposterior dimension increased significantly. The posterior and anterior facial heights remained in equilibrium, with no significant alteration in FHI. The tegumental profile presented significant improvement. Conclusion: The treatment performed produced correction of the apical basis with control of the horizontal planes and facial heights, and was effective for vertical control.|
