Clear Fusion Everlast Retainer
A clear, removable retainer with bonded acrylic for a more rigid, durable way to hold your teeth in position.
What it is
The Clear Fusion Everlast Retainer is a patented removable retainer. It combines a clear thermoformed shell, shaped over your teeth, with acrylic bonded to that shell. The bonded acrylic is the feature that distinguishes this appliance from an ordinary clear retainer.
Its job is retention: holding your teeth in their corrected positions after active orthodontic treatment. It is passive, which means it does not apply force to move your teeth or correct teeth that have shifted. Think “please stay here,” not “off we go again.”
“Everlast” is the brand name for a whole family of patented appliances made with this clear-shell-and-bonded-acrylic construction. On this page, the name refers specifically to the retainer in that family.
Who it’s for
Your dentist or orthodontist may choose this retainer when they want a removable appliance with more rigidity and durability than a plain clear retainer. It can help maintain your arch form—the curve of your row of teeth—and the way your upper and lower teeth meet after treatment.
Because it is removable, it depends on you following the wear schedule your clinician gives you. It is not intended for active tooth movement. If your teeth need correction rather than simply being held in position, your dentist or orthodontist will decide what kind of treatment is appropriate.
What to expect
The appliance is clear over the teeth, with bonded acrylic as part of its construction. It is more rigid and more durable than a plain clear retainer, but it is not unbreakable. Careful handling still matters.
There are more than one hundred color options, so your retainer can be considerably less predictable than “clear appliance” might suggest. Your orthodontist will guide the available choice for your design.
The retainer is also highly customizable. If it suits your treatment, your orthodontist may choose to add components such as an expansion screw or a bite plate. In general, many of the components that can be added to a conventional wire-and-acrylic Hawley retainer can also be considered for this appliance. These additions are always clinical design decisions for your orthodontist; they are not features you need to select on your own.
Your dentist or orthodontist will also set your wear schedule. Follow the plan made for your teeth, even if someone else’s retainer seems to have a more appealing timetable.
Caring for it
Handle your retainer carefully when putting it in and taking it out. Excessive force or improper insertion or removal can damage or break it, despite its more durable construction. Follow the cleaning, handling, and storage instructions given by your dentist or orthodontist rather than borrowing a routine meant for a different appliance.
Wear it according to the prescribed schedule and keep it stored safely when it is out of your mouth. A removable retainer cannot do its job when it is lost—or when it is enjoying an extended stay in a napkin or pocket.
When to contact your dentist
Contact your dentist or orthodontist if the retainer does not fit properly, becomes damaged or broken, or is lost. Do not force an appliance that is not fitting as expected. Your treating clinician can assess what has happened and advise you on the appropriate next step.
You should also contact them if you are having trouble following your wear schedule, are unsure how to insert, remove, clean, or store the retainer, or think your teeth have moved and may need active correction. Questions about colors, added components, or whether this design suits your treatment should also go to your own dentist or orthodontist.
