Fan-like expansion appliances
Fan-like expansion appliances are recommended for patients whose arches point somewhat forward. This irregularity is corrected by expanding the anterior segments only using a special screw fitted with a hinge; inverting the hinge provides expansion of the posterior segments.
The expansion screw also has other orthodontic purposes. For information on this topic, please contact our technical services.
Material required for manufacturing
– Upper stone model
– Lower stone model
– Wax bite in c.o.
Patients may choose the colour of their appliances. Regular acrylic is then replaced with coloured acrylic. One to three colours may also be chosen per appliance. These options actually encourage children to cooperate closely during orthodontic treatment
