The difference between twinblock appliance and muscle excitement

Different cases have different effects.

1, the muscle actuator is mainly aimed at correcting the symptoms of Angle Class Ⅱ malocclusion (mandibular retrusion) in children. Twinblock appliance is mainly used to promote the growth of mandible and retract the upper teeth at the same time.

2. The corrective force of 2.Activator comes from masticatory muscles. Before wearing braces, the masticatory muscles are in a state of balance. After wearing braces, the mandible will be guided forward and downward by the orthosis and then fixed in a new position. Twin-block can be worn all day, and the appliance is split. The maxillary and mandibular pads are inclined at a 45-degree angle during occlusal contact. Functional mandibular displacement corrects the relationship between maxilla and mandible, and quickly and functionally corrects malocclusion, which is usually used to guide the chin to extend forward.
