Retainers are the most effective method of ensuring teeth stay in their original positions after braces have been removed. Once braces or Invisalign treatment is complete, patients must then wear retainers to ensure the teeth stay in their new position. There are several different types of retainer that are available.
Vivera is produced by Invisalign. Designed using the same technology, Vivera retainers offer a very smooth and comfortable type of removable retainers. Vivera retainers are always provided in sets of three retainers. Your teeth information data for Vivera retainers is kept securely on the Invisalign cloud, so in future if you need new Vivera retainers, theses can be produced without taking new scans of your teeth as long as you have not had any major dental work carried out in the meantime.
Fixed retainers are a great way of ensuring teeth remain in place following the removal of braces. A fixed retainer is very discreet as they consist of a metallic wire bonded to the back of the front six teeth (available for upper or lower arches).
A Fixed retainer is always in place so patients do not need to worry about forgetting to wear it. In addition, a fixed retainer assists in stabilising mobile teeth, as well as reducing the risk of a relapse in heavily rotated teeth.
On the negative side, fixed retainers only fix the front six teeth and cannot stop the premolars and molars from moving. Also they can create oral hygiene problems as flossing the front teeth will be more difficult. Finally, fixed retainers can also change the bite as the wire and fillings can touch the tips of the lower teeth.
The Essix retainer is created using a clear thermoplastic mould. The appliance is almost invisible. This removable appliance provides support to the teeth to help prevent them moving out of their desired position. The advantage of an Essix retainer over a fixed appliance is that it retains every tooth in the mouth, not just the front six teeth.
It is important for patients to attend regular check-ups for their teeth and retainers. From time to time retainers will fracture and need replacing.
