Understanding twin block braces

Twin block braces are functional orthodontic devices that will primarily help to correct an underlying skeletal imbalance (or misalignment) of the jaw. Twin block braces are designed for patients whose lower jaw is positioned too far back in relation to the upper jaw.

While traditional orthodontics uses brackets and wires that help to shift teeth into a more desirable alignment, twin-blocks focus on correcting the alignment of the jaws themselves by means of the blocks. A twin-block consists of two separate plates that are removable:

Each plate has angled blocks that interlock when the mouth closes. The shape of the blocks allows them to hold the lower jaw in a slightly forward position. With time, this positioning of the lower jaw will stimulate normal jaw growth and improve the occlusion (the way the dental arches come together) between the upper and lower teeth.

The purpose of twin block treatment is not just to fix appearance, but to correct the underlying skeletal imbalance. Therefore, it is crucial to consider the specific characteristics of your individual skeletal structure when determining the best type of treatment to use.

When and why are twin block braces used?

Twin block braces are most effective during periods of active growth. This makes them especially valuable for children and early teenagers.

Common reasons orthodontists recommend twin block braces

Correcting these issues early helps guide natural development. Instead of waiting for problems to worsen, twin block braces intervene at the right time, often preventing more complex treatments later. This proactive approach naturally raises the question of how the appliance actually works.

How twin block braces work: Treatment mechanism and process

Twin-block braces work by influencing jaw position during growth, allowing the bones to adapt gradually.

Step-by-step twin-block treatment process:

Orthodontic assessment

The orthodontist evaluates bite alignment, jaw position, facial structure, and growth stage using clinical exams and imaging.

Custom appliance design

Upper and lower plates are custom-made to ensure comfort and effectiveness.

Wearing schedule

Patients typically wear the appliance for 18 to 20 hours a day. Parents often worry about twin block braces at school, but most children adapt quickly and wear them during school hours without issue.

Gradual jaw correction

By holding the lower jaw forward, the appliance stimulates bone adaptation over months.

Regular follow-ups

Adjustments ensure healthy progress and proper jaw positioning.

Transition phase

Once jaw alignment improves, the appliance is phased out, and attention shifts to tooth alignment if needed.

Treatment duration usually ranges from 12 to 24 months. Once the jaw correction phase ends, visible improvements begin to appear.
