Objective: Evaluate dental and skeletal changes resulting from the exclusive use of the cervical headgear for 15±4 months in the treatment of patients with Class II division 1 malocclusion. Methods: Differences between the beginning (T1 ) and immediately after the end of the therapy (T2 ) with the cervical headgear in growing patients (Experimental Group, EG, n = 23) were examined and compared, during compatible periods, with those presented by a group of untreated individuals (Control Group, CG, n =22) with similar malocclusions and chronological age. The cephalometric variables evaluated were: ANB, GoGn.SN, AO-BO, S’-ANS, S’-A, S’-B, S’- Pog and S’-U6 (maxillary first molar). The Shapiro-Wilk and Levene tests were used to evaluate the results.
