Hyrax
Indication:
-serious narrowing of the upper arch
-bilateral or unilateral cross bite
-treatment of cleft palate ( scar-tissue enlargement)
hyrax has a sceletal affect (childhood, puberty, 8-14 ages)
Expansion in serious II. and III. class cases
Hyrax is used in mixed and permanent dentition, while children are growing.
After the end of the development hyrax can’t be used (alone)
Affect:
- ripping („breaking”) of the sutura palatina mediana

Hyrax – permanent dentition
Stucture in permanent dentition:
-Metal bands on teeth 14,16,24,26,
6 or 12 mm expanding screw

primary molars)
6 or 12 mm expanding screw

Hyrax is never used in the lower jaw without surgery

Hyrax in adulthood
Used after surgical intervention (surgical
ripping)
In adulthood without surgical intervention
there is only dentoalveolar (tipping) affect of
hyrax

partly sceletal affect (bodily movement)
Build-up:
