7 Facts To Know About Orthodontic Expander

When talking about orthodontics, a common thought that is likely to occur in your mind is braces. However, apart from using braces, there other orthodontic treatments that can be used to improve teeth alignment and help you have a more beautiful smile. One of such treatments is an orthodontic expander. An orthodontic expander is more commonly used in children between five to sixteen years of age. The primary purpose of the device is to widen the maxilla (upper jaw) in children so that the upper teeth fit together with lower ones properly. The use of this orthodontic device is usually followed by braces that are used to straighten teeth after the room has been created by the expander. To know about this orthodontic device, take a look at his interesting guide listed below.

#1: What is an orthodontic expander used for?

An orthodontic expander, also known as a palatal expander or rapid maxillary expansion appliance is a device used to widen the roof or palate of the mouth to make enough room for permanent teeth to grow so that they do not become crowded in the mouth. Teeth that are crowded in the mouth often lack space in-between them causing to grow crooked or overlap each other. The expander is also used to widen the upper palate to treat bite alignment usually caused due to improper fitting of the upper and lower jaw.

#2: How does it work?

The expander is a custom-made an orthodontic appliance that fits at the roof of the mouth (near the palate) between the rows of back teeth. After it has been placed, it needs to be tensioned with a special key at intervals by the orthodontist to widen the arch in small increments.

Generally, right and left halves of a child’s upper jaw do not knit together until sometime after puberty. Until then, the upper jaw is soft and can be easily manipulated. When tension is applied, the expander gently moves the bone apart and cause new bone tissues to fill in space naturally.

The process of tightening the expander every day is done for a few weeks causing the spacing to improve dramatically. The appliance is left on for several weeks more to stabilize the expansion. A child may wear the expander for about 3- 6 months after which he or she may have to use a set of braces if required.

#3: What are different types of palatal expanders?

There are basically two types of dental expanders- removable and fixed

1: Removable- This type is usually suitable for early to mid primary school age children.

2: Fixed: Suitable for teenagers and young adults, this type of expanders are available in three designs to make it easier and effective.

  • · Hyrax type: In this type of fixed expander, the orthodontist can control the amount of expansion using and expander key.
  • · Superscrew type: Apart from allowing the orthodontist to manage the amount of expansion using a larger expander key, this of expander also allows teens and young adults to turn the expander themselves.
  • · Quad helix type: This type of fixed expander is usually used by orthodontist when a combination of expander treatment and movement of back teeth is required.

#4: Does an expander affect speaking and eating?

Speaking with expanders

The first week or two after fitting the appliance is usually considered the adaptation period to get used to the initial speech changes along with the changes in the perceptions by the tongue. It is noted that that children and teenagers usually adapt better to the changes than adults. The most common speech changes noticed are those that are more pronounced with the ‘th’ and ‘s’ sounds. However, after the first or second follow-up adjustment, the speech changes are significantly gone.
