Upper Hyrax Expander
The Hyrax arch expansion appliance is adjusted slowly twice per week. The arch expands painlessly 2mm per month. By expanding the arches this makes room for all the permanent teeth. Parents prefer this treatment because it eliminates the need for the extraction of permanent teeth. The other advantage of this arch expansion is it results in the patient having a beautiful broad smile. After the desired amount of expansion has been achieved the appliance must be left in for an additional 6 months to avoid a relapse.
