Retention is required at Smile Orthodontics following orthodontic treatment to prevent relapse of the final occlusal outcome. Deterioration can occur due to forces from the periodontal fibers surrounding the teeth pulling them back to their pre-treatment locations and deflecting occlusal contacts if the final occlusion is less than perfect. Age changes, such as continuous dentofacial growth and changes in the surrounding soft tissues, might potentially impact the durability of the orthodontic outcome. 

Why Is Retention Necessary?

We now know that this is just as crucial as the phase when the braces are doing their work and shifting the teeth into place. As braces become increasingly common, it is critical to understand the function retention plays in keeping your new smile looking beautiful and preventing teeth from shifting out of place.

Teeth migrate throughout life, mostly forward. We also know that teeth, known as the neutral zone, sit in equilibrium between the lips and cheeks on one side and the tongue on the other. Crowding occurs when the lips push back while the teeth move forward. This is visible as we age and our front teeth twist over.

Using braces to move teeth into a new position is inherently unstable. The teeth will naturally want to return to their previous locations to some extent. This is more likely if a tooth is shifted across a longer distance.

We also know that the entire face, including the jaw bones, changes over time. This will influence tooth placements. As a result, retention must be employed to help keep the teeth stable. This must also be a lifelong commitment. Failure to do so will inevitably result in tooth movement.

The Advantages of Retention

• Protects your orthodontic treatment investment by preserving the results.
• Reduces and potentially eliminates the need for future orthodontic treatment.
• Keep your smile in good condition.

Types of Retention

Clear Retainers

Clear retainers are virtually undetectable and, when properly worn, effectively hold the teeth in place. They can, however, be worn through by excessive grinding or become deformed when subjected to heat.

Removable (Hawley Retainers)

Typical Hawley retainers have a wire that wraps around the front surface of the teeth. Because nothing is covering the biting surface, the teeth naturally "settle" into position much better. They also allow for simple modification, which aids in the maintenance of teeth.

Fixed Retainers

The dentist must not rely on patient participation when using bonded retainers. Unlike detachable retainers, which might be misplaced or just not worn, fixed appliances are constantly present and ready to serve their purpose. Another advantage of permanent retainers is that they are challenging to detect because they are placed on the rear of the teeth. 

It is so critical that patients understand the significance of wearing retainers following orthodontic treatment. Visit Smile Orthodontics at 530 39th St, Des Moines 50312, or call (515) 274-4637 for the best dental treatments.
