HAAS with rests and acrylic
Bonded on bands, the HAAS with rests and acrylic exerts pressure on the bone part to enhance root expansion (The modified HAAS has the same characteristic). Adding acrylic to the HAAS is less hygienic. Nonetheless, any discomfort experienced by patients disappears a few days after debonding.
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
