Invisalign First: Clear Aligner Treatment for Children

What Is Invisalign First?

Invisalign First is a clear appliance system designed by Align Technology specifically for children's growing jaws and erupting teeth. Unlike traditional brackets, invisible and removable aligners are used.

This system is used during the mixed dentition period for jaw expansion, guiding teeth to the correct position, and creating space.

What Age Is It Suitable For?

Invisalign First is designed for children ages 6-10. During this age group, the mixed dentition period is active: baby teeth are still present while permanent teeth have begun erupting.

Not every child is suitable for this treatment. Suitability is evaluated after detailed examination and digital scanning.

Advantages of Invisalign First

Aesthetic appearance: Clear aligners are nearly invisible. Removable: Can be removed during eating and tooth brushing, maintaining oral hygiene easily.

Comfort: No metal wires or brackets means minimal risk of mouth injuries. The treatment process is digitally planned with 3D simulation preview of results.

How Does the Treatment Process Work?

The first step is detailed examination and digital intraoral scanning. Treatment plan is created with 3D modeling, predetermining how teeth will move at each stage.

New aligner sets are switched every 1-2 weeks. Average treatment duration ranges from 6-18 months. Aligners must be worn at least 20-22 hours per day.

Invisalign First or Traditional Braces?

Both methods have unique advantages. Invisalign First is superior in aesthetics and comfort, while traditional braces may be more effective for more complex issues.

The choice should be made based on your child's orthodontic condition, age, compliance capacity, and family preferences.

Frequently Asked Questions

What is Invisalign First and what age is it for?

Invisalign First is a clear aligner system designed by Align Technology specifically for children ages 6-10 during mixed dentition. It is used for Phase 1 orthodontic goals such as arch expansion, space management, and anterior alignment.

How does Invisalign clear aligner work?

The child's mouth is modeled by digital scan, the tooth movement sequence is determined in planning software, and a series of custom acrylic aligners is produced. Each aligner is worn 1-2 weeks; each stage advances teeth to the next position. The aligner must remain in the mouth 20-22 hours per day.

How long does Invisalign clear aligner treatment last?

Invisalign First (ages 6-10): typically 8-14 months. May extend to 18 months for complex cases. With regular wear and clinic check-ups (every 8-10 weeks), treatment completes within the planned timeline.

What do clear aligners do in children?

Invisalign First in children is used for: narrow palate expansion (upper transversal), alignment during mixed dentition, space creation for permanent teeth, correction of malocclusion from thumb-sucking or tongue-thrusting habits, and simple Class I issues.

Will treatment fail if the child does not wear the aligner?

Yes. The aligner must be worn 20-22 hours per day; if this discipline is not maintained, teeth do not reach the planned position, aligner sets need replacement (additional cost), and treatment extends. For children with poor cooperation, braces are preferred — pediatric dentist's decision.

What is the difference between Invisalign First and braces?

Invisalign First is removable + transparent + 20-22 hours/day required; braces are constantly in the mouth + visible + harder to keep hygienic. Braces suit all cases (including complex); aligners are ideal for mild-to-moderate cases. Cost: aligners are 40-80% more expensive. Detail: /en/blog/braces-vs-clear-aligners-children-comparison

What are the costs of Invisalign clear aligners?

In Turkey, private dental fees cannot be advertised under regulation (Law 1219). General comparison: with metal braces at 100% baseline, Invisalign First/Teen ~140-180%. For an exact figure, a written treatment plan after clinical examination is required.

Does treatment continue after Invisalign First?

In most cases, after Phase 1 (Invisalign First, 8-14 months), permanent teeth continue erupting so Phase 2 evaluation (ages 11-14) is performed. In Phase 2, full orthodontic treatment may continue with braces or Invisalign Teen. A retainer is mandatory in both phases.
