Orthodontic Elastomerics

A: Elastomerics are used in orthodontics to supplement the archwire's force and achieve tooth movements that would be difficult or impossible with brackets and wires alone. This includes correcting overbites, underbites, crossbites, and closing stubborn gaps. The consistent, gentle pressure applied by elastomerics helps to remodel the jawbone and move teeth more efficiently.

A: Yes, interarch elastics and power chains are available in various sizes, thicknesses, and force ratings (typically measured in ounces), allowing the orthodontist to customize the treatment for each patient. The appropriate size and force are selected based on the specific type and amount of tooth movement required.

A: Interarch elastics lose elasticity and force over time due to stretching, and from exposure to saliva and temperature changes. Your orthodontist will instruct you to change them often, usually two to three times daily, to ensure a consistent, effective force is always applied to your teeth. Wearing "tired" or worn-out elastics can slow down treatment progress.

A: Yes, both elastic ligatures and power chains come in a wide variety of colors, from subtle clear or gray to vibrant shades. You can often choose a new color at each appointment, which is a popular way for patients to personalize their braces and make treatment more fun.

A: The main difference is their function and structure: ligatures are individual elastic bands used primarily to secure the archwire to a single bracket. Power chains are a series of connected elastic rings that link multiple brackets together, allowing for a stronger, continuous force to move teeth or close gaps.

A: For patients with a latex allergy, many orthodontists offer latex-free elastics. These are typically made from a synthetic material and function in the same way as traditional elastics. It is important to inform your orthodontist of any latex allergy to ensure the correct materials are used.
