Invisible Orthodontics and Luxury in Every Detail.
A private orthodontics practice in Del Valle: one specialist, imaging in the same office, and a written quote on the table before you start.
One orthodontist, one office, every appointment with her.
Perea is a private orthodontics practice: a limited schedule and no rotating doctors. Every appointment, from the assessment to removing the attachments, is handled by Dr. Mariana Perea Sandoval.
Imaging is done in the same office —panoramic X-ray, lateral cephalogram and intraoral scan— so the diagnosis comes out of the first visit.

Invisible orthodontics, planned to a tenth of a millimetre.
Aligners are custom-made clear trays; each one moves two or three teeth a few tenths of a millimetre. The movement comes from the sequence, not the material: each tooth's full path is planned on a computer before the series is made.
Tooth-coloured attachments are placed for precise movements. Compared with braces, the difference is logistics: you take them out to eat and visits are further apart.
Scan and imaging
X-rays, photographs and intraoral scan on the first visit, with no impression paste.
Digital plan
Each tooth's path and the expected result, on screen, before you agree.
Aligner series
Between 20 and 60 trays; changed every 7 to 10 days, at home, with short check-ups.
Retention
Attachment removal, polishing and retainers. Retention is part of the treatment, not an extra.
- 20–60 aligners
- 7–10 days per tray
- Check-ups every 8–10 weeks
- 12–30 months
One case, start to finish.


Drag the handle or use the arrow keys to compare. Illustrative case; not a real patient. The timing and number of aligners do reflect what we see in practice.
Moderate lower crowding with wear on the canines
One in five assessments ends in a different recommendation: braces, combined treatment or surgery. When that happens, we explain why.

Find out your rangeFrequently asked questions
For the first two or three days with each aligner you feel pressure, especially when biting. It is not sharp pain and rarely needs a painkiller. After the first week your body gets used to the rhythm.
Face to face at conversation distance, hardly. What does show up close are the attachments, which are tooth-coloured but raised. On video calls they can't be seen; in flash photos sometimes they can.
Yes, because you eat without them. The condition is brushing before putting them back in: with the aligner on you can only drink water. The real habit change is rethinking what you snack on between meals.
Go back to the previous one the same day and let us know on WhatsApp. Depending on where you are in the series, you move ahead to the next one or we make a replacement: $1,200 and 7 to 10 days.
We hand over the rest of the series and the digital plan, so an orthodontist in your new city can continue without repeating imaging. If it is temporary, we follow up remotely with photos every three weeks.
No. About one in five assessments ends in braces, combined treatment or a surgical referral. When that happens, we explain why and what the alternative would cost.
Request a private consultation.
Write to us with what you would like to correct. If you have a recent photo of your teeth, biting down, facing the camera, we can tell you up front whether the case looks treatable with aligners and book the assessment.
We don't diagnose or close prices over chat; the quote is finalised in writing after imaging.
