Characteristics of Mooshield and Pre-Ortho

Mooshield and Pre-Ortho have the following characteristics

Mooshield -> transparent colored mouthpiece. It is shaped to cover the upper jaw and tongue.
Pre-Ortho → blue mouthpiece. It is shaped to cover the upper jaw and tongue and has bumpers on the backs of the front teeth.

The main difference between the two is that when you put the mouthpiece onIt is whether or not the back of the front teeth are supported by bumpers.

Pre-Ortho can start with the soft type and then switch to the hard type, which is more effective in treatment, as the patient becomes accustomed to it.

Effects of Mooshield and Pre-Ortho

The theory to improve the passive mouth is the same for both.

Mooshield and Pre-Ortho can be expected to improve the passive mouth through the following approaches

Guide the tongue to the correct position

Guide the tongue to the correct position

Both Mooshield and Pre-Ortho are expected to promote the development of the upper jaw by guiding the tongue into the correct position, thereby improving the passive mouth.

The correct position of the tongue is when it attaches perfectly to the maxilla when the mouth is closed.

In the case of a passive mouth, the tongue is not attached to the maxilla and is lowered, which often pushes the lower jaw from the inside and aggravates the passive mouth.

Mooshield and Pre-Ortho are designed to guide the tongue into the correct position when the mouthpiece is fitted, thus improving the position of the tongue, which is the cause of the passive mouth.

Furthermore, in the case of Pre-Ortho, the bumpers on the back of the front teeth may improve the position of the tongue, plus the force of the mouthpiece pushing the upper jaw outward from the inside, which may improve the bite more quickly than Moosiled.

Balancing the muscles of the tongue and lips

Both Mooshield and Pre-Ortho,Mouthpieces help to improve the muscular balance of the tongue and lips, which can be expected to improve the passive mouth.

Breathing and receiving are related and affect each other.

Weak lips, inability to close mouth, etc.

Mouth breathing for this reason can disrupt the balance between the forces that push the teeth inward and the forces that push the teeth outward with the tongue, causing a variety of malocclusions.

Mooshield and Pre-Ortho help improve mouth breathing, which is one of the causes of a passive mouth, by adjusting the muscle balance of the tongue and lips by putting the mouthpiece in place.
