Using a key to adjust an orthodontic expander, sometimes referred to informally in the context of braces treatment, involves a simple, step-by-step process to activate the appliance as instructed by your orthodontist. The key is specifically designed to fit into small holes on the expander, allowing you to turn a screw mechanism that gradually widens the appliance.
Understanding the Orthodontic Expander Key
An orthodontic expander key is a small tool used to activate palatal expanders or other types of expansion appliances. These appliances are often used before or during braces treatment to widen the upper jaw or create space in the mouth. The key fits into specific points on the expander to make adjustments.
Steps to Turn Your Expander
The process for using the key, as demonstrated in orthodontic care, involves these key actions:
- Find the Hole: "You're going to put the key and find the hole." Locate the small hole or slot in the expander that you need to turn. This is usually accessible from the front or bottom of the expander.
- Insert and Let Go: "And once you find the hole you want to let go and make sure that the key stays." Insert the key firmly into the designated hole. Once seated, release your grip slightly but ensure the key remains in place. This confirms the key is properly engaged before turning.
- Push to Turn: "Then you want to push." Use the key to push or rotate the screw mechanism in the direction indicated by your orthodontist. This motion turns the screw, widening the expander slightly. After the turn, the next activation hole should become visible.
Always follow your orthodontist's specific instructions on how many turns to make and how often. Each turn is typically a fraction of a millimeter.
What is an Orthodontic Expander?
An orthodontic expander is a custom-made appliance designed to slowly widen a narrow jawbone, most commonly the upper jaw (palate). By applying gentle pressure, it encourages bone growth or separation along the midline suture of the palate, creating more space for teeth and improving the bite.
Different types of expanders exist, including:
- Rapid Palatal Expanders (RPE)
- Bonded Expanders
- Removable Expanders
The key is typically used with fixed expanders like RPEs, which are cemented onto the back teeth.
Step | Action | Purpose |
---|---|---|
1. Locate the Hole | Find the correct activation slot on the expander. | Ensure accurate key placement. |
2. Insert & Engage | Insert the key firmly; ensure it stays in place. | Prepare for the turn. |
3. Turn the Mechanism | Push or rotate the key in the specified direction (e.g., towards back of mouth). | Activate the expander to widen the jaw. |
Properly using the expander key as directed by your orthodontist is crucial for successful treatment outcomes.
