Tooth tissue-borne (KBME) expander
Tooth-borne (Hyrax) expander
Bone-borne (MIDME) expander
In this tooth tissue-borne appliance, the occlusal surfaces of the molar and premolar teeth and half of the palatinal and buccal surfaces are covered with heat polymerized acrylic. Hyrax expansion screw is in the midline, as far as possible to the palate positioned close and parallel.
In this tooth-borne expansion appliance, orthodontic bands are placed on the right and left 1st premolar and 1st molar teeth of the patients and the bands are soldered to the Hyrax expansion screw. The expansion screw is in the midline, as far as possible to the palate positioned close and parallel.
This bone-borne expander includes 2 mini-screws with a diameter of 1.6 mm and a length of 10 mm on the right and left sides, coinciding between the roots of the 2nd premolar and 1st molar teeth in addition to the hyrax expansion screw.
