Retainer

Retainers are usually fabricated by the orthodontist or general dentist who performed the orthodontic treatment. This is customarily done by taking a mold, or impression, of the newly straightened teeth and fabricating the retainer out of wire and/or acrylic material.

There are two types of Retainer
The fixed type of retainer is usually a thin wire worn across the back of the lower or upper front teeth, which is bonded in place with a cement similar to that applied on the brackets of braces. Despite the fact that this type of retainer takes a little more work to keep clean, it has the best outcome because the bonded wire will hold the newly straightened teeth.
The removable type of retainer is usually a combination of a wire going across the front of the lower or upper front teeth held in place with a combination of acrylic material and hooks (or clasps) that insert in and around the back teeth to hold the retainer in place.

Disadvantage :

  • The obvious disadvantage of a removable retainer after braces is the fact that it can be lost or damaged and can even melt or change shape if it is exposed to high heat.
  • It is also very important not to leave the retainer lying around the house since pets love to chew them!
