A series of computer-generated, nearly invisible aligners that fit over the teeth.
Aligner Systems
Comfortable, removable aligners that gradually move your teeth into position.
invisible Braces
These systems are a simple, fast and invisible way to align teeth.
Fixed appliances
A variety of brackets depending on your individual needs and requirements.
Sectional systems
With simple Newtonian mechanical principles the teeth can be moved.
There are several methods of Prealign that Dr Mew uses.

Balanced zone
The teeth sit in a balanced zone between the tongue on the inside and the lips and cheeks on the outside. If this balance changes the teeth move. In some disease the cheeks are lost and the teeth move outwards and there are incidents where the tongue is lost and the teeth move inwards. The balance seems to be affected mainly by the resting position or posture, and also by the functional habits of, the surrounding muscles. If the bones of the skeleton are in the correct position and teeth are not in the correct position it is due to an in correct balance between these muscles. Although there is some hereditary functional and postural patterns there is a great scope to affect the position of the teeth by retraining these muscles.

Move the zone and move the teeth
Changing habits is not easy and this requires some dedication to achieve a long term change, but if during orthodontic treatment no change is made it is likely that the teeth will in time return to their original position and as a consequence long term retention of orthodontic results is now universal. Although Dr Mew routinely prescribes long term retention, and provides backup systems of retention, he is very keen to attempt to change the actual causes of the problem. A permanent change in the resting balance of these muscles will permanently change the position of the teeth. The teeth positions of people with strokes, facial palsy’s and nerve damage all are affected due to a change in the resting muscle positions, and how else do the other 4629 species of mammals have perfectly aligned teeth, from when they are born to when they die, other than good natural muscle balance.

Myotherapy literally means muscle therapy, and Oral Myotherapy is the science of training of the orofacial musculature, including modification of habits. Function (and posture) tends to follow form and by changing the form of the dental arch and position of the teeth greatly helps oral myotherapeutic training. It is possible but very difficult to change the muscle balance without any physical change in the dental positions. Channing habits is not easy, many of us have poor body and back postures, we are able to stand correctly and do at times but maintaining this permanently is almost impossible for most of us.

Cause of the problem
Since the soft tissue of the muscle are difficult to study even for short periods the knowledge of their long term postural effects are limited, however many innovative studies and natural case examples have shed light on this matter. A swallow is one of the few bodily actions that we start as a conscious effort and continues as a subconscious process, we do not control the movement of the larynx or the wave of peristalsis that moves down the oesophagus. To initiate a swallow we stimulate certain initiating or trigger points within the mouth, try having this patter and it is surprisingly difficult to initiate a swallow. As suckling or bottle fed infants the swallowing initiation pattern is triggered largely by the action of the cheeks and sideways and forward movement of the tongue. In a natural world we would move to from breast feeding to a mix of breast feeding and hard food between 12 and 18m. However in a modern world this change is happening much earlier and the food given is so soft that it can literally be sucked in. Thus the normal change from an infantile to an adult swallowing patter does not happen, leaving most adults with a modified infantile swallowing pattern where they are sucking in on their teeth whenever they swallow. The swallowing action changes the resting postural position of the tongue which then often rests between the teeth rather than behind them. The balance has then been greatly changed. Without the outward pressure of the tongue on the side of the teeth, they progressively move inwards crowding in the process and further reducing space for the tongue. Fixed appliance orthodontics with the extraction of teeth in early teens then tends to exacerbate this problem.

Training regimes including lip sealing, swallowing and tongue training, lip bumpers and chewing exercises these follow the principles of the tropic premise and orthotropics. The balance between the lips and tongue that causes most malocclusions can be affected to ease treatment and improve the stability of the final result. Although posture has the greatest effect, posture and function are highly interrelated, so training start with function.

  • Swallowing exercises before meals
  • Nocturnal lip seal
  • Swallowing meals
  • Day time tongue and lip posture
Exercises are only as good as the individual doing them.

Good function nice face
The size and shape of any muscle is determined by its function and posture and there is mounting evidence that improving these factors improves the shape and size of the lips and cheeks, which are mainly muscle. Individual who recruit there cheek muscles to swallow have large cherubic cheeks, it is often assumed to be due to fat but there is rarely excess fat in this area. Chubby cheeks or large cheek muscles is usually associated with narrower dental arches, since the size of the cheeks pushes the teeth more. However it is lip form that is the most affected by posture and function, notice people who hang their lower lip down, they usually have a large droopy lower lip and incorrect lip function on swallowing and ruin an otherwise perfect lip form. Notice people with perfect lip form and they nearly always have an ideal swallowing pattern. It is as important not to use some muscles as to use the correct ones and the ultimate change and the ultimate change happen on a change in posture.
