Introducing
MDSA® Components.
The latest and
most versatile Anti-Snoring/Sleep Appliance available is made with
the MDSA®
components.
The MDSA® concept
was designed in conjunction with Australia's leading Dentist's,
Sleep Physician's and Dental Technician's to overcome the
limitations of all other appliances available to treat the needs of
their patients.
Over the last 4
years the MDSA® concept has been subjected to extensive scientific
and clinical testing and evaluations.
Efficacy of
Positive Airways Pressure and Oral Appliance in Mild to
Moderate Obstructive Sleep Apnea

This paper published AJRCCM
online 16/6/04 confirms the efficacy and effectiveness of the MDSA®
it now has published medical evidence to support its use as an
alternative to CPAP.
Abstract:
The efficacy of currently – recommended treatments is uncertain in
patients with mild to moderate obstructive sleep apnea (apnea –
hypopnea index 5-30). A group of 114 sleep clinic patients with
apnea- hypopnea index 5-30 have participated in a randomized
controlled crossover trial of 3 months treatment with each of nasal
continuous positive airways pressure, a mandibular advancement
splint and a placebo tablet. Outcomes were sleep fragmentation and
hypoxemia, daytime sleepiness, quality of life, neurobehavioral
function and blood pressure.
Both active treatments improved sleep outcomes, but positive
pressure had a greater effect.
Quality of life, symptoms
and subjective but not objective sleepiness improved to a similar
degree with both treatments, however many of the improvements seen in the
neuropsychological function and mood were no better then the
placebo effect.
Some aspects of nocturnal blood pressure were improved with the
splint but not with continuous positive airway pressure.
This study has shown that although both continuous positive airways
pressure and mandibular advancement splint effectively treated
sleep-disorder breathing and sleepiness, the expected response in
neurobehavioral function was incomplete. This may be due to the
splint having a lesser therapeutic effect, and the continuous
positive airways pressure being poorly tolerated and therefore used
less in this patient group.

This independent
NH & MRC funded trial now confirms the unique features and
clinical benefits of the Australian, designed and manufactured
MDSA® and sets it apart from other splints that have not been
compared to the Gold Standard (CPAP) and placebo in a randomized
controlled cross over trial.
The versatility/comfort
and patient acceptance of the MDSA® meant that only 5 out of
99 patients had teeth unsuitable for the MDSA® and could not be
fitted with the appliance. Only a further 2 could not tolerate.
Acclimatization period was 1-3 weeks maximum for patients.
This is far less than previously reported for Orthodontic type oral
appliances (19.7±8.8weeks range 5 - 40 weeks, Mehta etal
AJRCCM Vol 163 2001) - ( 8±4weeks range 2 -
22weeks, Helen Gotsopoulos et al AJRCCM Vol 166
2002)
The trial also confirmed that the
MDSA design does not impede tongue space when the jaw is advanced.
The AHI increase in uncontrolled oral appliance trials has
been attributed to a problem with the design of the oral appliance:
however we found that significantly fewer subjects had an AHI
increase with the MDSA® than with placebo. The trial showed
that 2.6% of patients were non responders with the splint the same
as for CPAP.

The
MDSA® component based
appliance is now the appliance of choice.
It is protected by International
Trade Mark registrations, Patents and Registered Designs in
selected country's.
Manufactured from patients own
impressions using dual laminate hard/soft splinting material
ensures the greatest retention, comfort and durability for the
wearer.
An appliance manufactured with the MDSA®
Components offers easy titration, full lateral and controlled
vertical movement and exceptional
ease in inserting each night.
Patient can insert the TOP plate (which includes the Adjustor
Component), then the BOTTOM plate (which includes the shelf). Push
their bottom jaw forward to the full passive protrusion position
and up to just engage the the adjuster component in the
TOP.
This should have
the patient in a clinical effective position of around 75% of full
passive protrusion. Adjustment will be required overtime which can
be performed before insertion.
Full lateral movement.
MDSA® component
appliance can be manufactured with posterior support yet
maintain full lateral
movement.

Acrylic
MDSA® Components
are now supplied with new adjustment marks, logo and change in
final cleaning process to overcome any chance of residue
staining.
