appliance for fundamental widening of the upper jaw

The appliance is designed for expansion of the upper jaw. Narrowing of the upper jaw can lead to crossbite, high arch palate, restricted nasal breathing, deflecting the mandible in occlusion and later also its asymmetric growth. It often occurs to limit the growth of the lower jaw, overbite of the upper incisors and unaesthetic facial profile.

The tapered upper dental arch is sometimes associated with the small size of the upper jaw. Lower jaw then goes beyond in all dimensions (the so-called. Pseudoprogenie) .

Another complication is usually not enough space for the teeth with crowding incisors and the canines growth disorders .

Hyrax is a device that can reliably, quickly and without much burden on the patient expand the upper arch and thereby promote the growth of the surrounding tissues. It is firmly affixed to the teeth and after treatment is removed without damaging the teeth.
