BACKGROUND: In the present paper, the authors analyze the effect of the “Swallowing Occlusal Contact Intercept Appliance” (SOCIA) in treatment of children with hyperdivergent Class II malocclusion. This functional appliance has no intra-oral anchorage, but induces a continuous periodontal, muscular, and articular stimulation.
METHODS: Twenty-six patients with hyperdivergent growth and class II malocclusion were selected and treated with SOCIA appliance. Cephalometric analysis was performed before treatment (T1) and immediately after the treatment (T2).
RESULTS: After 24 months treatment authors observed a modification of maxillary growth with a reduction of the divergence with an increase of the posterior facial height, a modification of condylar inclination and forward position of the a hyoid. No modifications was observed about the ANB angle. After treatment the open bite was resolved with a reduction of the inclination of the upper incisors.
CONCLUSIONS: SOCIA is a reliable functional appliance in growing age patients with a hyperdivergent pattern growth, anterior open bite and class II molar malocclusion.
