Whether it’s 24 hours a day or just at night or just once a week, the length of time required for retainer wear is different for everyone. And eventually that can change, too.

PROBLEM:
With a vacuum-formed appliance that fits over the occlusal surface (regardless of whether the retainer is an upper or a lower), the patient’s teeth don’t fit together as they should. This can lead to bruxing which can result in a broken retainer or unwanted tooth movement.

SOLUTION:
An esthetically pleasing (invisible) appliance that does not cover the occlusal surface – yet fits better and is strong enough (and rigid enough) to maintain optimal tooth stability.
 
The COR Functional Retainer
COR stands for “Cosmetic Orthodontic Retention.” Excellent for use immediately after orthodontics, the COR appliance is the ideal solution for keeping teeth straighter and stronger than ever before.  
    
Perhaps most significantly, it delivers premier stability and permits totally natural bite function because the biting surfaces are not covered.
