MYO DENTAL has developed a number of patented devices
which are now widely used. Chewing on their carefully
measured resistance for just a few minutes each day can produce
rapid improvement in a number of common dental conditions for
both adults and children.

About the MYO Products
The myofunctional device or Myo Munchee, is considered one of the most significant developments in the field of interceptive orthodontics.
The products are inexpensive, costing on average between $70 - $80 including GST. As the website
shows, they are easy to use - and it is easy to encourage a child to use them - and they produce
Originally designed (over 12 years ago) as an aid to plaque removal, its potential as a preventive orthodontic device was quickly realised.
Dr Kevin Bourke explains:
"The Myo has a marvellous capacity to stimulate bone and develop a better arch form when used in young children. It has proven to be an enormous aid especially in cases of anterior open bite"
Produced from hybrid latex or silicone, the MYO has hundreds of tiny projections on its inner surfaces to provide a cushioned force to the teeth and gums.
When chewed vigorously with the lips together it exercises the craniofacial muscles and encourages nose breathing. Eminent orthodontists such as Dr RM Ricketts and Dr Thornton Taylor, consider craniofacial exercise as important for proper facial development.

Dr Bourke feels the high incidence of malocclusion in modern society is probably due to our diet of soft foods.
"Stasis (the stoppage of flow of fluid) is the basis of disease" he says.
"Children go from milk to slop, never adequately exercising the craniofacial musculature. In addition, colds, thumbsucking, asthmatic conditions and a variety of other ailments play a part in disrupting the stomatognathic system".
With the current trend towards early correction of many orthodontic problems the Myo is gaining global popularity. "Almost all malocclusions, both dental and structural, are present from infancy and respond rapidly to interception" he says.
There is no room in Dr Bourke's approach for what he calls "supervised neglect".
With parental assistance and encouragement children two years and older can be treated and, unlike conventional appliances, the Myo can be used right through ages six to seven years when the permanent incisors and first molars are erupting.
The home carer, usually the mother, not the dentist, is responsible for treatment of two to five year olds.
