Systems and methods for moving and/or restraining tissue in the upper respiratory system

A system comprising

• an appliance sized and configured to be worn inside a mouth, the appliance including a body shaped to releasably engage a hard tissue region within the mouth so that the appliance can be selectively fitted into and removed from the mouth, the body including a first component material, and
• a second component sized and shaped to be implanted within a region of the tongue, said tongue having a portion disposed in the mouth, said region of the tongue being a region of the portion of said tongue disposed in the mouth, the second component including a second component material that magnetically interacts with the first component material via a force of attraction so that, when the appliance is worn within the mouth, magnetic interaction between the first and second component materials stabilizes a preferred orientation of the tongue within the mouth,
• wherein the region of the portion of said tongue disposed in the mouth is greater than one-half of the distance from the tip of said tongue to the back of the portion of said tongue disposed in the mouth,
• wherein said distance starts from the tip of said tongue, and
• wherein said back is opposite said tip.
