Rapid Maxillary Expansion
The Rapid Maxillary Expander will over 10-14 days create a palatal expansion of about 5mm.
Placebo Appliance
The Placebo Appliance looks exactly like the Rapid maxillary Expander but the expansion screw does not work. When the expansion screw is activated it does not create a palatal expansion.
