To re-establish the correct jaw relationship and occlusion

Myolay™ is a built-up composite technique used mainly in the primary and mixed dentition to assist in arch development and jaw alignment and is used in combination with MRC's appliancesMyolay™ involves building up the four lower deciduous molars (or the first and second molars when indicated in older patients) by two to four millimetres with composite resin that is specifically shaped depending on the indication. By re-establishing the correct relationship between the upper and lower jaws, Myolay™ permits habit correction to occur more effectively and arch development to continue without any occlusal interferences. Myolay™ must be used when nasal breathing has been established as the technique is ineffective if the patient cannot keep their mouth closed and teeth in contact.

Myolay™ Design Features and Indications

The design features of the Myolay™ composite are suited to establishing the correct jaw relationship and assisting with development when combined with MRC's appliances. It is most effective in growing patients and is mainly used in the primary and mixed dentitions.

Directions for Use

The Myolay is applied to the lower deciduous molars only using regular composite bonding protocolsThe composite is usually coloured to improve patient acceptance and allow easier removal if necessary. If they are placed on deciduous teeth, removal occurs with exfoliation of deciduous teeth.

Instructions for application:

  • Step 1

    Clean the occlusal surface of the teeth that the Myolay™ is to be placed on with a slow speed brush and pumice. Rinse thoroughly.

    Step 1
  • Step 2

    Follow the manufacturer's composite bonding instructions, then apply composite and shape depending on indication.

  • Step 3

    Instruct the patient to wear their Myobrace® or Myosa® appliance (depending on indication) for one to two hours while awake and overnight while sleeping.

    Step 3
