How The A2 Works

A2 is a three-stage appliance system suitable for the permanent dentition. The A2 provides arch development as well as habit correction and dental alignment. It is made of medium-hardness polyurethane and provides arch development and puts small force on the teeth for improved dental alignment. It is available in regular and large. MRC has pioneered the use of appliances to correct myofunctional habits in growing children and has proven success in orthodontic correction without braces. This treatment can also lead to better facial development in growing children. The key to this treatment is correcting the position and function of the tongue, obtaining correct nose breathing and retraining the oral muscles to function correctly. Although these corrections are more difficult in adult patients, the treatment principles are the same to obtain optimum results.

Patient Selection

The A2 is made of firm polyurethane, and is suitable for mild malocclusion. The A2’s firm material is designed to be used after the A1, and exerts more aligning forces on anterior teeth.

Directions for use

The A2 must be worn for one to two hours each day and overnight while sleeping and always remember to follow these few simple steps:

• Lips together at all times except when speaking or eating.

• Breathe through the nose, to assist the development of the upper and lower jaws, and to achieve the correct bite.

• No lip activity when swallowing, which allows the front teeth to develop correctly.

• Improved dental alignment.

• Improved facial development.

Cleaning the Myobrace A2
The A2 should be cleaned under warm running water every time the patient removes it from their mouth.
