Functional Appliances

Twin Block functional braces are a specialized type of orthodontic appliance designed to correct specific bite issues, particularly in growing children and teenagers. They are named "Twin Block" because they consist of two separate blocks, one for the upper jaw and one for the lower jaw, which work together to achieve the desired orthodontic corrections. A removable retainer at the end of treatment is necessary to preserve the result.

How Do Twin Block Braces Work?

Twin Block braces are effective for treating malocclusions, such as overbites and underbites, by encouraging proper jaw positioning. The design of these braces aims to achieve the following:

  • Lower Jaw Advancement: The lower block is designed to promote the forward movement of the lower jaw. This advancement helps in aligning the lower teeth with the upper teeth properly.
  • Upper Jaw Retraction: Simultaneously, the upper block guides the upper jaw backward. This dual action creates a balanced and harmonious bite relationship between the upper and lower teeth.
  • Muscle Adaptation: Over time, the muscles around the jaw adapt to this new position, resulting in improved facial aesthetics and a functional bite. 

Advantages of Twin Block Braces:

  • Effective Correction: Twin Block braces are particularly effective in treating certain bite problems, making them a valuable orthodontic tool.
  • Growth Guidance: They are often used in younger patients during their growth phase to guide the development of the jaws.
  • Improved Aesthetics: Correcting bite issues can lead to a more attractive facial profile and smile.

Considerations for Patients:

  • Age: Twin Block braces are most effective in younger patients with developing jaws. Early intervention can yield optimal results.
  • Compliance: Patients need to wear the braces as directed by their orthodontist for the treatment to be successful.
  • Adjustments: Regular check-ups and adjustments are necessary to monitor progress and make any necessary changes to the appliance.
  • Maintenance: Proper cleaning and care of the braces are essential to maintain oral hygiene during treatment.

Other Functional Appliances

Other types of functional appliances are available but they are not as easy to wear as Twin Blocks.

A Medium Opening Activator

Thi is is a functional appliance that is constructed as a single piece that covers both the upper and lower teeth. As this comes in a single piece, it makes speech difficult.

Invisalign Mandibular Advancement

Also known as Invisalign MA, this is an innovative orthodontic treatment option that combines the benefits of Invisalign clear aligners with a mandibular advancement component that aims to advance the lower jaw progressively in the same way that a Twin Block does.

What is the treatment’s duration?

The duration of treatment is usually between 6 – 18 months but can vary depending on the case, the problem that causes it, and whether the child will wear the device as recommended by the orthodontist.

Twin Block functional braces are a valuable orthodontic tool for correcting specific bite issues, particularly in growing patients. They work by guiding the development of the jaws, leading to improved facial aesthetics and a functional bite. If you believe that a patient may benefit from Twin Block braces, consult with your orthodontist for a comprehensive evaluation and treatment plan.
