How long does Invisalign treatment take?

The average Invisalign treatment lasts 12 to 18 months, depending on the complexity of the case. Simpler cases (Lite) can be completed in 6-8 months. At the assessment consultation, we present a treatment plan with the estimated duration and a 3D simulation of the result.

Is Invisalign painful?

Invisalign causes mild discomfort during the first few days with each new aligner, which is normal and indicates that the teeth are moving. This discomfort is significantly less than with traditional braces and typically resolves within 2-3 days.

Can I eat anything with Invisalign?

Yes! One of the great advantages of Invisalign is that the aligners are removable. You can eat whatever you like, simply removing the aligners before meals and brushing your teeth before putting them back in.

What is Diamond Apex status?

Diamond Apex is one of the highest levels of Invisalign certification, awarded to clinics with a high case volume and proven results. Alinea, led by Dr. Cesar Pimentel, is an Invisalign Diamond Apex Provider, guaranteeing maximum experience and expertise.

Does Invisalign work for complex cases?

Yes. With our team's Diamond experience, we treat complex cases including crossbite, overbite, open bite and severe crowding. Dr. Pimentel assesses each case and recommends the best approach.

Straighten your smile discreetly and comfortably

Invisalign is the world's most advanced invisible orthodontic system, with more than 15 million patients treated globally. At Alinea Premium Oral Care, we are certified Invisalign Diamond Apex providers — one of the highest levels of certification — with Dr. Cesar Pimentel leading a team of orthodontists with more than 25 years of experience. We use exclusive Soft Pulse technology to safely and comfortably accelerate tooth movement, and iTero intraoral scanners for complete digital planning with a simulation of the result before treatment begins.

How does Invisalign work?

Invisalign uses a series of removable, clear aligners custom-made with 3D SmartTrack technology. Each set of aligners gradually moves the teeth to the ideal position programmed in ClinCheck — the simulation software that allows the final result to be visualised before treatment starts. Aligners are changed every 1-2 weeks and should be worn 20-22 hours a day. The Smart Force technology built into the aligners ensures precise, predictable tooth movements.

Advantages of Invisalign at Alinea

Unlike traditional braces, Invisalign is practically invisible, removable for eating and brushing, more comfortable, and allows the final result to be visualised before treatment begins. At Alinea, we use exclusive Soft Pulse technology that emits micro-pulses to accelerate tooth movement, reducing treatment time by up to 50%. We combine this with the iTero intraoral scanner to eliminate uncomfortable traditional impressions.

Invisalign for every case

Invisalign treats a wide range of orthodontic cases, from mild crowding to complex crossbites and overbites. At Alinea, we offer Invisalign Comprehensive (full cases), Invisalign Moderate (medium complexity), Invisalign Lite (mild cases) and Invisalign Teen (adolescents with a compliance indicator). Dr. Cesar Pimentel assesses each case individually and recommends the best option.

Invisalign vs. traditional braces

While both systems are effective, Invisalign offers significant advantages in comfort, aesthetics and practicality. It is removable (making hygiene and eating easier), does not cause sores on the oral mucosa, requires less frequent appointments, and the result is predictable from the outset thanks to the 3D simulation. For cases requiring very specific movements, the orthodontist may recommend fixed braces or a combination of both.

How treatment is planned

Assessment consultation: Clinical assessment, iTero intraoral scan and 3D simulation of the result (ClinCheck).
Digital planning: The orthodontist designs the tooth movement plan and the patient approves the simulated result.
Aligner fabrication: Custom aligners made in the USA with SmartTrack technology for comfort and precision.
Treatment start: Delivery of the aligners with usage instructions (20-22 hours/day) and placement of attachments.
Periodic follow-up: Appointments every 6-8 weeks to monitor progress and deliver new sets of aligners.
Retention: After alignment, fitting of fixed or removable retainers to maintain the result.
