How the Myolay™ works

Myolay is a composite buildup technique used to assist in arch development and jaw alignment in combination with the Myobrace System.

The Myolay System involves building up of the 4 lower deciduous molars by 2-4 mm with composite to assist in arch development, Class II and Class III correction as well as cross-bite correction.

Arch development
Some patients with a narrow arch-form require additional arch development in combination with the use of their Myobrace® appliance. Myolay™ is particularly suited to be used in late primary to early mixed dentition stages. It can “unlock” the occlusion, allowing the Myobrace® to expand the maxilla with Dynamicore™ and corrected tongue position.

Class II correction
The Myolay can be used for Class II correction by applying inclined planes to encourage forward positioning of the mandible. This also prevents the mandible being locked into the habitual occlusion.

Class III correction
The Myolay can be used for Class II correction by applying inclined planes to encourage backward positioning of the mandible. This also prevents the mandible from being locked into the habitual Class III occlusion. In addition, Myolay™ is helpful in reducing the incisal edges of the deciduous canines.

Cross-bite correction
Myolay can be placed on the deciduous or permanent molars with inclined planes to use occlusal forces to push the upper maxillary posterior teeth outwards, and the lower posterior teeth inwards. This can also correct a midline shift of the mandible.

Myolay must be used in conjunction with the Myobrace system to maximise effectiveness.
