Invisible Aligners

Straighter teeth, discreet treatment

Straighten your teeth discreetly with clear aligners.

About This Treatment

Invisible aligners are a modern and discreet alternative to traditional braces. We use custom-made transparent aligners that are virtually invisible, allowing you to correct teeth positioning without compromising your aesthetics during treatment. Each set of aligners is custom-made to gradually move your teeth to the ideal position.

We Understand Your Situation

Misaligned or crowded teeth can affect much more than the appearance of your smile. Many people feel self-conscious when smiling in photos, avoid certain social or professional situations, and may even experience difficulties with chewing or oral hygiene. If you have considered correcting your smile but hesitated due to the appearance of traditional braces, invisible aligners may be the ideal solution for you.

Orthodontic Conditions

Conditions We Treat with Clear Aligners

Clear aligners effectively correct a wide range of orthodontic issues, from mild to moderate complexity. Here are the conditions we commonly treat:

  • Mild to Moderate

    Crowding

    When teeth overlap due to insufficient space in the jaw, making cleaning difficult and increasing cavity risk.

  • Mild to Severe

    Spacing (Diastema)

    Gaps between teeth that can trap food, affect speech, and impact smile aesthetics.

  • Mild to Moderate

    Overbite (Deep Bite)

    Upper front teeth excessively overlap lower teeth, potentially causing wear and gum irritation.

  • Mild to Moderate

    Underbite

    Lower teeth protrude past upper teeth, affecting chewing function and facial profile.

  • Mild to Moderate

    Crossbite

    Some upper teeth sit inside lower teeth when biting, causing uneven wear and jaw strain.

  • Mild to Moderate

    Open Bite

    Front teeth don't touch when back teeth are closed, affecting biting and speech clarity.

  • Mild to Moderate

    Midline Shift

    Center line of upper and lower teeth doesn't align, affecting facial symmetry and bite.

  • Mild to Severe

    Tooth Rotations

    Individual teeth twisted out of proper alignment, creating cleaning challenges and aesthetic concerns.

FAQ

Frequently Asked Questions

Find answers to the most common questions about this treatment.

What are invisible aligners?

Invisible aligners are a system of removable, transparent aligners that correct teeth positioning discreetly and comfortably, without the need for metal brackets or wires.

How long does invisible aligner treatment take?

Treatment duration varies between 6 to 18 months, depending on case complexity. Simpler cases can be resolved in a few months, while more complex cases may take longer.

Can I remove the aligners to eat?

Yes, one of the great advantages of invisible aligners is that they can be removed for eating and drinking. It is recommended to wear the aligners for at least 22 hours a day for best results.

Do invisible aligners cause pain?

You may feel some discomfort in the first few days of each new aligner, but it is generally much more comfortable than traditional braces. The initial pressure is a sign that the treatment is working.

What is the price of invisible aligners?

The price varies according to case complexity and the number of aligners needed. We offer an initial consultation where we evaluate your case and present a personalized quote with payment options.

Do invisible aligners work for all cases?

Invisible aligners are effective for most dental misalignment cases, including crowded teeth, spacing issues, or irregular bites. Very complex cases may require complementary treatments.

How often should I visit the clinic during treatment?

Generally, follow-up appointments are scheduled every 6 to 8 weeks to monitor progress and deliver new aligners. The frequency may vary depending on the case.

Can I play sports with invisible aligners?

Yes, you can practice sports with the aligners. For contact sports, we recommend removing the aligners and using an appropriate mouthguard for better protection.

Are invisible aligner results permanent?

Results can be long-lasting if you use retainers as recommended. After treatment, it is essential to wear a retainer to keep teeth in the correct position.

From what age can you use invisible aligners?

Invisible aligners can be used by teenagers from age 12-14, when most permanent teeth have erupted. They are also very popular among adults of all ages.

How do you choose which aligner system to use for my case?

The choice of aligner system is made after a complete evaluation of your case. We consider the complexity of treatment, your personal preferences, budget, and specific goals. We work with the leading systems on the market, which allows us to select the most suitable solution for each patient, rather than always recommending the same brand.

Are there differences between the various aligner systems?

Yes, each system has its own characteristics in terms of materials, planning technology, and treatment protocols. However, all premium systems we use can achieve excellent results. The difference lies in finding what best suits your specific case, and that's what we do during the evaluation consultation.

How does digital technology improve aligner treatment?

We use 3D intraoral scanners to create precise digital impressions, eliminating traditional molds. Advanced software with artificial intelligence plans each treatment stage, allowing you to visualize the final result before starting. 3D printing ensures aligners perfectly fitted to your needs.

Are invisible aligners better than traditional braces?

Each system has its advantages. Aligners are more aesthetic, comfortable and allow better oral hygiene. Traditional braces may be more effective in very complex cases. During consultation, we evaluate the best option for your specific case, potentially combining both techniques.

What types of dental problems can be treated with invisible aligners?

Aligners effectively treat: crowding, spacing between teeth, crossbite, overbite, open bite and general misalignments. Mild to moderate cases have excellent results. More complex cases may require attachments (small bumps on teeth) or combined treatment.

How can I see the final result of my treatment before starting?

At the initial consultation, we perform a 3D scan of your mouth and use simulation software to show how your teeth will look after treatment. This digital simulation allows you to visualize the final smile and make adjustments to the plan before starting, ensuring you are satisfied with the expected result.

Do aligners affect speech?

There may be a slight adjustment period of 1-2 days when placing the first aligners, during which you may notice a minor speech change. Most patients adapt quickly and speak normally. Modern aligners are very thin and well-fitted, minimizing any impact.

How should I clean my transparent aligners?

Hygiene is fundamental in invisible orthodontics. You should clean your aligners whenever you remove them, brushing them gently with lukewarm water (never hot) and a soft brush. For a deeper clean and to avoid odors, you can use cleaning crystals or tablets specific for aligners. Good hygiene ensures the device remains invisible and discreet.

Can I drink coffee or smoke with the appliance?

To maintain the transparency and aesthetics of your invisible appliance, we recommend removing the aligners when smoking or consuming beverages that can stain (like coffee, tea, red wine, or curry). Additionally, hot liquids can deform the thermoplastic material of the aligners, compromising the success of the treatment.

What happens if I lose an aligner?

If you lose an aligner, contact our clinic immediately. Do not advance to the next aligner without medical guidance. Generally, we recommend going back to wearing the previous aligner until a replacement is provided, ensuring your teeth do not move undesirably during this interval.
