Clear Aligners and Invisalign in Santiago

Led by Dr. Camila Sampaio, Invisalign Diamond Provider continuously since 2021 and Orthodontics Specialist from Faculdade São Leopoldo Mandic (Campinas, Brazil). iTero 5D and ClinCheck digital workflow at a boutique clinic in Vitacura.

Why Diamond Provider matters

Align Technology, the maker of Invisalign, classifies its certified orthodontists into tiers based on annual case volume. The Diamond Provider tier identifies the group treating the highest volume of certified Invisalign cases worldwide each year.

Dr. Camila Sampaio has held this designation continuously since 2021. It is not a promotional badge. It is verifiable data reflecting clinical experience accumulated across hundreds of cases each year, with the learning curve only sustained volume can deliver.

In practice, that volume translates into three things: the ability to anticipate which movements are realistic and which need refinements before starting, mastery of the ClinCheck software and of attachments to access complex movements, and speed handling unexpected events that take weeks in lower-volume clinics.

The workflow, step by step

1. iTero 5D scan. We capture the full dentition in minutes, with no silicone impressions. The scanner detects interproximal caries, gingival recession, and occlusal wear in the same session through NIRI and the diagnostic modules built into the device.

2. ClinCheck planning. On the 3D model, Dr. Sampaio designs the full sequence: movements, attachment positions, refinement timing, and final result. We review it on screen together before approving the start.

3. Fabrication and delivery. Align Technology fabricates the custom SmartTrack aligners. At the start session we bond composite attachments, deliver the first series, and walk through wear and hygiene protocols.

4. Check-ups every 6 to 8 weeks. We verify the teeth are tracking the ClinCheck plan. If there is drift, we apply refinements: additional aligners calculated from a new scan. Refinements are included in the initial plan.

5. Vivera retention. At completion we deliver Vivera retainers manufactured by Align with the same material as the aligners. For cases with relapse risk in the anterior segment, we add a fixed lingual retainer.

Who it is for

Adults who dismissed orthodontics years ago because of the visual impact of braces. Professionals who need alignment without disrupting work, travel, or social life. Patients with complex malocclusions who were told elsewhere their case required surgery or fixed braces. Teens with permanent dentition who prefer Invisalign Teen.

Cases we treat routinely: mild to severe crowding, gaps between teeth, crossbite, open bite, deep overbite, protrusion, relapse after previous orthodontics, alignment prior to veneers or aesthetic rehabilitation.

Cases requiring combined evaluation: severe skeletal discrepancies, surgical indications, compromised periodontium. In the first consultation we define whether Invisalign is the right option alone or whether to combine with other treatments.

Frequently asked questions

What does Invisalign Diamond Provider mean and why does it matter?

Invisalign Diamond Provider is the recognition Align Technology gives to orthodontists with the highest annual volume of certified Invisalign cases worldwide. Dr. Camila Sampaio has held this designation continuously since 2021. In clinical practice that translates into proven experience in complex cases, mastery of the ClinCheck software, accurate reading of which movements are realistic, and speed iterating refinements when needed.

Why iTero 5D rather than another intraoral scanner for Invisalign?

iTero is the intraoral scanner developed by Align Technology, the maker of Invisalign. Integration with ClinCheck is native, which lets us send the scan directly to the planning software with no loss of precision, simulate the final result on the same day of the first consultation, and detect interproximal caries, gingival recession, or occlusal wear early through NIRI and the diagnostic modules built into the device. It is the standard for advanced cases inside the Invisalign network itself.

Does Invisalign work for complex adult cases?

Yes. Recent advances in SmartTrack, precision attachments, and movement options allow us to treat malocclusions that five years ago required orthognathic surgery or fixed braces: severe crowding, open bite, deep overbite, crossbite, protrusion, and moderate skeletal discrepancies. Diamond Provider status implies high volume in these case types. In the first consultation we define whether Invisalign is the right option or whether a combined approach is preferable.

How long does an Invisalign treatment take?

It depends on case complexity. Mild cases, such as limited anterior crowding, complete in 6 to 8 months. Moderate cases, in 10 to 14 months. Complex cases may require 18 to 24 months with refinements included. The ClinCheck simulation we show at the first consultation gives a precise estimate before starting.

What is the difference between Invisalign and other clear aligners?

Invisalign is the system with the most accumulated clinical evidence and the most years on the market. SmartTrack is a patented material that exerts more controlled forces than generic plastics. The library of validated movements, attachments designed specifically for each movement, and integration with iTero 5D enable a predictability other systems still cannot replicate. For simple cosmetic crowding, other systems may work; for full or complex cases, Invisalign remains the standard.

What are attachments and why are they used?

Attachments are small tooth-colored composite shapes bonded to the tooth surface that let the aligner leverage tooth movement in the correct direction. Without attachments, aligners can only perform basic movements. With attachments, the system accesses complex movements: extrusion, intrusion, severe rotation, root torque. They are removed without marks at the end of treatment.

Is Invisalign painful?

No. It is normal to feel slight pressure when starting each new set, a sign your teeth are moving. The sensation is significantly less than traditional bracket adjustments and fades within 24 to 48 hours. Patients coming from previous fixed-bracket treatment describe Invisalign as noticeably more comfortable.

How many hours a day should I wear the aligners?

Between 20 and 22 hours a day. They are removed only to eat, drink hot or colored beverages (coffee, tea, wine), and for oral hygiene. The predictability of the treatment depends directly on compliance. For teens, Invisalign Teen includes built-in compliance indicators so the clinical team can confirm wear time.

Do I need retainers after treatment?

Yes. As with any orthodontic treatment, retainers are essential to maintain results long-term. Without retention, teeth gradually return to their previous position. We offer Vivera retainers (made by Align Technology with the same material as the aligners) for removable retention, and fixed lingual retainers behind the incisors when the case justifies it.

Does Atria Sampaio see patients from outside Santiago?

Yes. Digital planning lets us condense the start of treatment into a few visits: one consultation with iTero 5D scan and ClinCheck design, and one session for delivering the first aligners and bonding attachments. Subsequent check-ups every 6 to 8 weeks are coordinated around patient availability, and for international patients we adapt the schedule to the length of their stay.

Who performs the Invisalign treatments at Atria Sampaio?

Dr. Camila Sampaio. She is an Orthodontics Specialist from Faculdade São Leopoldo Mandic (Campinas, Brazil), Clinical Assistant Professor at NYU College of Dentistry, and has held Invisalign Diamond Provider status continuously since 2021. Her academic background includes more than 55 peer-reviewed publications in international indexed journals on dental aesthetics, materials, and digital dentistry.
