    Abstract:
    Patients with Class II malocclusion and severe overjet are often dissatisfied with their facial disharmony. Although temporary skeletal anchorage devices (TSADs) are now widely used in orthodontic treatment, traditional anchorage devices should not be overlooked as a treatment option. Proper design of traditional anchorage can achieve 3-dimensional control of incisors and molars as efficiently as TSADs in some patients with severe malocclusion. We used traditional anchorage devices, including a transpalatal arch and a Nance palatal arch, combined with a utility arch to treat an 11-year-old Chinese girl with a skeletal Class II malocclusion and severe overjet. The space was closed in 2 steps to protect molar anchorage. Facial improvement, especially smile esthetics, and Class I molar relationship and overjet correction were achieved in 17 months of treatment. Follow-up records 22 months after treatment show that the results remained stable.
