Ok so you've
had the impressions made its a couple of weeks later and you now
have your MDSA splint.
An MDSA Splint appliance is made of a semi heat-sensitive acrylic
for wearing comfort. Though it is now set, exposure to excessive
heat may cause it to distort or deform. Do not leave the splint in
direct sunlight or near radiant heat.
Handy Hint: To assist in the
fitting of the MDSA Splint nightly run the appliance under semi hot
tap water prior to inserting it into your mouth. This will insure
easy insertion and immediate comfort when wearing the appliance.
Make sure that the water is not too hot as the metal parts of the
appliance may cause injury. Warming it prior to insertion also
extend the life of the appliance in cold areas. NEVER use a
microwave or oven to heat the appliance.
Care and Cleaning of your MDSA Oral Appliance:
Clean the appliance daily with a non-whitening, non-abrasive
toothpaste, using a "soft" head toothbrush. Take a little extra
effort on the screw mechanism to clean into the crevasses too.
Once per week, soak the appliance in a commercial denture cleaner,
for no more than 20 minutes, then rinse the appliance thoroughly
When your appliance is not in your mouth, store it dry (not sitting
in liquid of any kind) in the case provided. Keep it in a safe
place, for some reason children and dogs love to play with Oral
MDSA Splint in and taking it out again:
Place the appliance in warm water for approximately 40 to
60 seconds to soften the material. Place the lower appliance on the
teeth and seat it completely by pressing firmly first at the front
of the unit then on the back right and back left portions of the
appliance. Insert the Upper Tray into the mouth in the same manner.
When the appliance is fitted firmly, yet comfortably onto the upper
and lower teeth, move your lower jaw forward and seat the lower jaw
plate over and onto the hook of the upper jaw tray. Finally close
together to be certain that the appliance is fitted completely and
comfortably. If the unit is loose or not fitted correctly, follow
the “removing instruction” then repeat installing the unit.
To remove MDSA Splint first bring your lower jaw forward so as the
lower plate clears the top hook then open jaw apart, wide enough to
clear the hook, and relax. Using both hands place your fingers on
the left and right side upper borders of the upper splint and press
firmly downward "rocking" the appliance from one side to the other
until it releases from the teeth (be careful not to twist the
appliance on the teeth). Grasp the front of the device and remove
from mouth. Then, remove the lower tray by placing your thumbs on
both sides of the appliance at the lower borders firmly push
upwards on one side then the other to "rock" the lower appliance
off of the teeth (again being careful not to twist the appliance on
the teeth). If the appliance is retentive, try rinsing your mouth
with very warm water. If it requires use of hot water remove your
appliance on a regular basis you should contact your Dentist
Adjusting the screw mechanism:
Your MDSA Splint has been custom made for you and is designed to
provide maximum effectiveness over a long period of time, much
longer than many of the off the shelf rigid splints. The patented
screw mechanism allows you to advance the lower jaw’s position,
which may increase its effectiveness, or you may move your jaw’s position back in
case of related jaw discomfort. NOTE: Always consult with your
Dentist or Physician prior to adjusting the MDSA Splint.
Resist adjustments of the screw mechanism during the first week
after you receive your appliance (unless advised by a Dentist or
Physician) . It is important to allow your jaw and teeth to become
comfortable with the appliance fitted at night. Monitor your
snoring, daytime sleepiness and quality of sleep during that
symptoms are continuing and upon advice from your Dentist or
Physician, simply place the alan key provided with the appliance
into the socket and turn the front assembly from your right cheek
to your left cheek (in a counterclockwise direction) to move the
lower jaw position forward. Moving the key in the opposite
direction shall allow the jaw to retract further.
If you have any jaw pain or lingering tooth discomfort, discontinue
use of the appliance and contact your Dentist or Physician
It may take 4 weeks to determine the most effective jaw position
for managing your snoring and apnea condition. It is hoped though
that you will notice an immediate improvement in your symptoms.
However, it is usually necessary to advance the jaw slowly over a
period of time to improve the effectiveness of the appliance and
maintain the comfort of your jaw and teeth.
