What you need to know about orthodontic expanders - Scottsdale Phoenix AZ | Budd Orthodontics

So your orthodontist said your child needs a palatal expander?  Here is some helpful information to become familiar with what to expect moving forward.

How does it work?

Palatal expanders are a commonly used appliance in orthodontics to make room for crowded teeth, correct crossbites, increase the size of the airway and/or widen a narrow upper jaw. Many of us have held a newborn baby and felt the “soft spots” on their tender little heads. Those “soft spots” are cartilage sutures that have not yet closed in their developing skulls. In much the same way, each of us has a cartilage suture in our upper jaw that splits the upper jaw into two halves. At the onset of puberty, that suture starts to fuse together into one bone. However, prior to the fusion of the bone the upper jaw can be expanded significantly using a palatal expander. As the palate expands, the cartilage is stretched and stimulates bone to fill into the space created by the expander. If given enough time to stabilize, the jaw will then fill in with bone at the new “corrected” width. Pretty amazing!

Interestingly, the lower jaw does not have a suture to match the upper jaw, which limits the amount of expansion you can achieve on your bottom teeth.

What does it look like?

 

The expander connects to your top molar teeth with little metal rings called “bands”. Wires connected to these bands rest gently on the teeth. There is an activating mechanism in the center of the expander that can easily be turned with a “key” that is given to each patient. Your orthodontist will show you how to use the key – it is really easy! The key will slowly and gently widen the jaw with each activation about 0.25 mm. In our office, one activation is recommended each night before bedtime. Over the course of each 4 day period, the jaw widens just 1 millimeter. While this may not seem like much, within just a few weeks you will have created much more space for the teeth to fit into. You may experience some slight discomfort as the suture starts to open, but this process is relatively pain-free.

As the suture opens, you will often see a space open up between the two front teeth. This is normal and is evidence that the expander is doing its job. After your expansion is complete, the space will naturally start to close as the crowded teeth unravel. Any residual space will be closed with your braces.

How do you maintain the expander?

Keeping your teeth healthy while going through treatment with a palatal expander is pretty easy – it just takes a little extra time and effort when you are brushing and flossing your teeth. Your orthodontist will likely give you some extra little brushes to help you clean well around your expander and show some spots that are commonly missed. A Waterpik or similar device is also a helpful tool to clean around the expander. You should brush your expander the same way you would brush your teeth - until it looks clean and shiny with no white “fuzzies” (plaque) sitting on it.

Before you know it, you will have the stunning smile you have always wanted. Good luck! If you have any questions regarding expanders or orthodontic treatment, give our office a call.

What is two-phase orthodontic treatment? - Scottsdale Phoenix AZ | Budd Orthodontics

August 26th, 2019

Two-phase orthodontic treatment generally means that part of the orthodontic treatment is completed while the patient still has some baby teeth.  This part of the treatment is referred to as Phase I and is usually completed sometime between ages 7-10.  After the eruption of the remaining adult teeth, the second phase of orthodontic treatment involving full upper and lower braces is completed.  This part of the treatment is referred to as Phase II. The idea behind this type of treatment is that some of the more severe orthodontic problems can be treated more effectively by treating them in two stages.

Some examples of problems that can be treated effectively by doing two-phase orthodontic treatment are:

  • Creating spacing for severely crowded teeth or repositioning teeth that are developing incorrectly
  • Creating facial balance through influencing jaw growth
  • Reducing the risk of fracture or uneven wear to protruding teeth or teeth in crossbite
  • Preserving space for teeth that have not erupted
  • Correcting harmful habits like thumb sucking
  • Preventing damage to gum tissue around teeth that are erupting outside of a normal position

The type of appliances that are used in Phase I while patients still have baby teeth varies a lot.  It can be as simple as a special retainer to correct one tooth that is really crooked or as complicated as partial upper and lower braces with a palatal expander.  If a Phase I treatment has already been completed, Phase II is generally more straightforward involving traditional braces or Invisalign as most of the more severe orthodontic problems have already been corrected in Phase I treatment.  Minor problems like mild spacing or crowding, mild overbites, and mild to moderate misalignment can generally be treated just as effectively with a single phase treatment at around age 11-13 depending on the age of eruption of the adult teeth.
