What Are Internal (Interceptive) Braces for Children?

Internal braces for children are an early orthodontic treatment aimed at correcting or guiding the growth of the upper and lower jaw bones before all permanent teeth have erupted.

Typically applied for children aged 4 to 9 years.
Main goal: Prevent bite problems and excessive jaw protrusion before the issue becomes more severe and harder to treat.
Unlike traditional braces, internal braces focus on jaw growth, not just teeth alignment.

Is the Treatment Painful?

Initially, the child may feel slight pressure or discomfort on the teeth and jaw.
This usually disappears after a few days as the child gets used to the appliance.

How Long Does the Treatment Take?

Typically 6 months to a year or more, depending on the severity of the condition and type of appliance used.
Daily use of the appliance accelerates treatment and increases effectiveness.

Does Every Child Need Surgery?

Not all cases require surgery.
Most children improve with appliances and supportive exercises alone.
Surgery is only needed for severe cases after jaw growth is complete.

Does the Appliance Affect Speech or Eating?

Some children may experience temporary mild difficulty in chewing or speaking during the first few days.
Adaptation occurs gradually, and speech and chewing improve over time.

Can the Appliance Be Removed During Meals?

Removable appliances can be taken out while eating.
Fixed appliances remain in place throughout the treatment.
It's important to clean teeth after every meal to maintain oral health and appliance hygiene.

Daily Care

Brush teeth and clean the mouth thoroughly after each meal.
Clean removable appliances according to the dentist’s instructions.
Regular follow-up visits with the dentist are essential to monitor progress.

Are the Results Permanent?

With adherence to treatment and regular follow-up, results are usually stable and permanent.
In rare cases, if jaw growth continues after treatment, additional follow-up may be required.

What Does Internal (Interceptive) Braces Include?

Also known as functional or interceptive orthodontics, this approach addresses jaw and facial growth issues early.

Main goal: Correct early bite problems before the child completes growth.
Guides upper and lower jaw growth, improves smile aesthetics, and enhances oral functions.

Difference Between Preventive and Interceptive Orthodontics

Criteria	Preventive Orthodontics	Interceptive (Internal) Orthodontics
Goal	Prevent dental/jaw problems before they start	Detect and correct problems early before they worsen
Suitable age	3–6 years (before permanent teeth erupt)	6–12 years (with first permanent teeth erupting)
Focus	Oral habits, hygiene, early tooth loss, jaw guidance	Correct jaw protrusion, underbite/overbite, crowding, early jaw growth issues
Appliances	Growth guidance devices, mouth guards, tongue barriers	Functional jaw appliances, teeth/jaw repositioning devices
Benefit	Reduce need for future braces or surgery	Reduce severity, improve bite, prevent future chewing or speech issues
Duration	Usually short, with periodic follow-up	Several months to a year or more depending on severity and growth

Duration of Internal Braces for Children

Factors affecting treatment duration:

Severity: The more severe the bite or jaw protrusion, the longer the treatment.
Type of appliance: Functional appliances, expanders, or habit-correcting devices vary in duration.
Child’s age and jaw growth: Younger children often need shorter treatment if started early.
Compliance: Daily use and exercises speed up results.

Approximate duration by appliance type:

Appliance Type	Expected Duration
Functional jaw appliances	6 months – 1 year
Palatal expanders	4 – 8 months
Habit appliances	3 – 6 months with follow-up
Early fixed braces	6 months – 1 year or more

Important notes:

Progress is evaluated every 4–6 weeks to adjust the appliance.
Some children may need a follow-up phase or additional braces after permanent teeth erupt.
Following dentist instructions and daily hygiene ensures optimal results on schedule.

Children Who Benefit Most from Internal Braces

Children with bite problems – underbite or excessive overbite affecting chewing and speech.
Children with crowded teeth – lack of space for permanent teeth.
Children with harmful oral habits – thumb sucking, tongue thrusting, or lip biting.
Children with abnormal jaw growth – lower jaw growing faster or slower than upper jaw.
Children with chewing or speech difficulties – issues with specific sounds or eating.
Children with family history – genetics play a role in jaw and bite issues; early intervention is beneficial.

Causes of Internal Braces for Children

Protrusion or underbite/overbite – corrects imbalance between upper and lower teeth.
Crowding – creates space and guides teeth growth.
Early tooth loss – prevents neighboring teeth from drifting.
Harmful oral habits – corrects finger sucking or tongue pressure.
Jaw growth issues – guides proper upper and lower jaw growth.
Chewing or speech difficulties – improves oral functions gradually.

Types of Internal Braces for Children

Functional Jaw Appliances
- Guides forward/backward jaw growth.
- Examples: Twin Block, Herbst Appliance.
- Benefit: Corrects bite naturally during growth, reduces future surgery need.
Palatal Expanders
- Widens narrow upper jaw for permanent teeth space.
- Reduces crowding and improves bite.
Early Fixed Appliances
- Corrects protruding or misaligned front teeth before jaw growth completes.
- Guides teeth placement and improves smile.
Habit Appliances
- Corrects thumb sucking, tongue thrusting, or lip biting.
- Protects jaw and teeth development.

Notes:

Appliance choice depends on age, severity, and jaw growth.
Usually applied before jaw and teeth growth completes.
Regular follow-ups are essential.

Stages of Internal Braces Treatment

Diagnosis and Evaluation
- Clinical exam of teeth and jaws.
- X-rays to assess jaw growth and teeth alignment.
- Medical/family history for genetic or habit-related factors.
- Identify the problem: jaw protrusion, bite, crowding, or habits.
Planning
- Select the right appliance based on age and severity.
- Set treatment duration and schedule.
- Explain usage and exercises to child and parents.
Appliance Placement
- Install functional, expansion, or habit-correcting devices.
- Teach child care and cleaning routines.
- Initial adaptation may take a few days.
Treatment Follow-Up
- Regular visits to monitor progress and adjust appliance.
- Evaluate bite and teeth alignment.
Supportive Exercises
- Jaw forward exercises, proper swallowing, lateral jaw exercises.
- Enhance appliance effectiveness and speed results.
Completion of Interceptive Phase
- Appliance is removed or paused after early problem correction.
- Sometimes followed by traditional braces as more permanent teeth erupt.

Possible Side Effects of Internal Braces

Temporary discomfort or pain – usually subsides after a few days.
Temporary difficulty in speech or eating – improves with adaptation.
Mouth or gum irritation – can be alleviated with dental wax or appliance adjustment.
Need for continuous follow-up – essential for optimal results.
Temporary tooth movement – natural part of treatment.
Continuous pressure sensation – necessary for guiding growth but may feel uncomfortable initially.

Tips to Minimize Side Effects

Follow the dentist’s instructions for appliance use.
Regularly monitor the child to adjust the appliance as needed.
Teach the child proper jaw exercises to ease adaptation to the appliance.
