What happens when you get orthodontic
braces... step by step
Getting Braces: Part
One
First you brush.
Your teeth and gums have to be spotless...!
We'll
show you on Stacy how we place braces
With
the lips and tongue held back by a clear plastic retractor, an etching
agent is applied for 60 seconds to each tooth. This prepares the enamel
to accept the bonding agents which hold the bracket to the tooth.
Here we are just
showing you on an upper tooth how we do it so you can see better.
After 60 seconds,
the etch is rinsed off and a sealant chemical is applied to each tooth
for about 5 seconds to treat the enamel so the light cured bonding
material "sticks" to the tooth.
The doctor
carefully places each bracket in exactly the right place on the tooth
with a small tweezer.
The
bracket is then checked for angulation and any adjustments are made
before activating the bonding material which is between the back of the
bracket and the tooth. The bonding agent will not set until
exposed to a strong ultra violent light. This gives us time to
adjust the bracket to just the right spot on the tooth.
The
plasma light is shown on the bracket for about 3 seconds to activate and
set the bonding material.
After
all the brackets are placed, a soft, body temperature activated wire is
placed and held in the bracket with a soft plastic ligature on each
bracket. The ligatures come in various colors and can be changed
at each appointment. Here we used a gray colored ligature because
Stacy didn't want her braces to show too much for the first day out.
Maybe she'll do pink next visit.
Stacy
checks out how we are doing and approves the new look.
Thirty minutes later
and we have braces on the lower front teeth and a new "braceface".
Brittany is getting
her braces on the upper teeth first, so we'll see how it's done for her
Brittany is just loving those lip stretchers, but they are pretty
comfortable and they keep those lovely lips off the teeth while the
etching chemicals are applied to each tooth before the brackets with the
bonding material are placed.
The
back side of each bracket is coated with bonding material which is
squirted on from a gun which contains the bonding "glue".
The doctor
places each bracket on the tooth.
Next
the assistant cures the bonding material with a bright plasma light
which begins the curing process in the bonding material. The
bonding material doesn't set up until the light activates it.
That way, we have plenty of time to adjust the position of each bracket
precisely.
Once
all the brackets are on and the bonding material set completely, which
only takes about five minutes, we are not ready to place the first wire
in the bracket.
The
first wire we use is the thermally activated soft wire which produces
very low forces and moves the teeth gently. Thermal wire is soft a
room temperature and stiffens with body temperature. If the
teeth are really crowded, then we chill the wire before placing it to
make it really soft before we put the wire in the bracket.
A
body heat-activated thermal wire is woven around and through each
bracket.
When
one or two teeth are just too far out of line, we will skip those teeth
and come back and engage them in the bracket later.
The
wire is held in place with the colored ligatures which are placed on
each tooth per the patient's request for a given color or pattern.
In this case, Brittany wanted two colors alternated. We can place
a silver ligature to match the braces so these is no color too.
Whatever way you want it. You can change your colors at each
appointment if you wish.
Did we
say colors? We've got colors. Dozens of colors...!
You
can see here how the colored ligature slips around the bracket.
Those
teeth we skipped before, are now tied to the wire with "power chain"
which is an elastic plastic chain. The chain allows us to reach up
to teeth which are really too far out of line to bend the wire. As
the teeth come down, then we move the wire into the bracket.
Brittany is all done and one happy camper. Total time to put her
top braces on...about twenty five minutes.
Here's
Brittany one year later and almost finished...
