Aim: To evaluate and compare the dental and skeletal changes of AdvanSync and Herbst appliance using CBCT. Materials and methods: A single blinded clinical trial was conducted with a total of 39 Class II division 1 patients during their skeletal growth spurt and were randomly divided into three groups; AdvanSync group (n = 13), Herbst group (n = 13), and fixed mechanotherapy group (n = 13) who matched for skeletal age, sex, and craniofacial morphology. CBCT was taken at Pretreatment (T1) stage and Post-treatment stage (T2) after 8 months of appliance placement. Treatment changes were evaluated between these two time points using dentoskeletal variables. Statistical comparisons were done using one-way ANOVA with post hoc Tukey\'s test. Results: A significant mandibular growth increment with Herbst and significant headgear effect with AdvanSync appliance was observed as compared to fixed mechanotherapy group. Both appliances showed significant increase in total mandibular length, anterior, and posterior facial height. Conclusion: The AdvanSync and Herbst appliance resulted in correction of the Class II malocclusion. The AdvanSync showed more dentoalveolar effects but less mandibular length increment when compared to Herbst. Clinical significance: This study suggests that if the Class II malocclusion is due to retrognathic mandible mainly and the patient is in peak pubertal growth spurt, Herbst is the appliance of choice as this appliance supports more skeletal changes while in Class II malocclusion with a more dental and less skeletal contribution AdvanSync appliance works well. Also the age of the patient and compliance support the use of the AdvanSync appliance as for this appliance treatment duration is lesser and it is more patient friendly.
