Objectives: The aim of the present study was to evaluate the correlation between headgear wear duration and correction of skeletal and dental Class II malocclusion in preadolescent patients. Materials and Methods: The study material consisted of pre and posttreatment lateral cephalograms, and actual headgear wear hours calculated from data recorded monthly by an electronic timer device, (Compliance Science System (CSS) and Affirm Smart Headgear Modules, Ortho Kinetics, Vista, California, USA) of 30 patients (14 female and 16 male) treated with cervical headgear for 12 months. The mean age was 10.43 ± 1.07 years. Initial and progress cephalograms were analyzed according to skeletal and dental landmarks to evaluate treatment effect of the appliance. The actual number of hours of appliance wear was calculated by data from timer modules collected every monthly visit. Statistical analysis was performed by using SPSS 24.0. Results: While a sagittal growth was still observed in the group using the headgear for less than 12 hours, restriction of sagittal growth of maxilla was achieved in the group using the cervical headgear over 12 hours daily. Conclusions: The cervical headgear is still used in orthodontics to restrict the forward growth of the maxilla in Class II division 1 patients with a normal or low angle profile. By means of objective data for monthly appliance usage, this study showed that in order to achieve the targeted results the cervical headgear should be used at least 12 hours daily.
