You may want to check out this resource - simsorthodontics.com/palate-expander-vs-quad-helix/From the article A palate expander is a dental appliance that is used to specifically widen the roof of the mouth. They are used to correct many possible scenarios in a patient’s mouth. Typically, palate expanders are used to correct crossbites— for when a child’s upper jaw and palate are too narrow to create a normal bite, overcrowding and difficulty in breathing ability properly – for when a patient may have a more narrow or deep jaw. A Quad Helix, somewhat similar to a palate expander is a fixed expander for the upper jaw to straighten teeth. However, unlike a palate expander, no key is required to activate a quad-helix. The appliance is cemented to the molars and has four active springs that work to widen the arch. Specifically, a quad helix can be used for treatment to widen the upper jaw in the front and/or back in order to rotate the upper first molars. Additionally, a quad helix is placed to widen the upper arch so that room can be made for crowded teeth or correct a crossbite. It is recommended that a three-month retention period be followed once the desired expansion has been achieved for the placement of a quad-helix. . |
