tooth movement and jaw expansion
The palatal expander is an orthodontic appliance used to widen the roof of your mouth. It is attached to the upper molars by bonded bands and works by putting gradual pressure on the left and right halves of the upper jaw. This pressure gently expands the palate and new bone is generated in its place. A palatal expander, also known as a rapid palatal expander, rapid maxillary expansion appliance, palate expander, orthodontic expander, Haas, or Hyrax, is used to widen the upper jaw (maxilla) so that the bottom and upper teeth will fit together better. This is a common orthodontic procedure. Although the use of an expander is most common in children it can be and has successfully been used in adults, although the effects of expansion are slightly more uncomfortable. Also, depending on the amount of correction and age of the patient, it may result in surgical separation of the maxilla. Palatal Expansion. Palatal expansion is a combination of tooth movement and jaw expansion. It works by widening the two halves of the upper jaw, called the palate. The two halves are joined together by a 'suture' in the middle of the roof of the mouth. A palatal expander is a device designed to help us do that. Palatal expanders create more space in a child's mouth by gradually widening the upper jaw. Although this may sound scary, it's really quite easy — both to do and to tolerate. How Expanders Work. An expander is custom-made for each individual and fits over several top teeth in the back of the mouth. The appliance has two halves that are connected in the middle with a screw. To activate the device, you simply turn the screw a very small amount each day with a special key. Rapid Palatal Expansion Procedure. Palatal expanders and dual arch expanders (DAEs) are two appliances commonly used in our practice, particularly in Phase I treatment. We made this expander video to show patients and parents in a step-by-step fashion what will occur the day they get their expander. A palatal expander is the proper orthodontic appliance to for this type of treatment and prevention. Once the expander is secured in the child’s mouth, it will slowly widen the upper jaw to prevent or treat malocclusions. It is an easy and tolerable process. It is most effective in children due to the gradual fusion of the two halves that make up the upper jaw. This makes the Rapid Palatal Expander more effective.
