Orthodontic retainers are either removable or fixed appliances that
are placed after the completion of orthodontic treatment. They are
used to stabilize the teeth so that the surrounding bone and soft tissues can
conform to the new dental alignment.
Many factors can cause teeth to change position throughout life.
Factors such as tongue thrust habit, facial growth changes,
mouthbreathing, clenching habits and a natural tendency for
teeth to move with aging may result in dental changes without retention.
The goal of retention is to limit dental changes after orthodontic
treatment and maintain the teeth in a good functional and
attractive position. In this way, patients will maintain their beautiful
smile that was achieved as a result of orthodontic treatment.
