How clear aligners work
After a scan or impressions, a series of clear trays is made. Each tray applies gentle pressure to move the teeth a small step, and you move to the next tray as scheduled. Because the trays are removable, you take them out to eat and brush. Orthodontic work is led by Dr. Lalita Rutchakitprakarn, orthodontist (license ท.9453), MSc in Orthodontics from National Yang-Ming University (Taiwan).
Who are clear aligners for?
- Minor crowding or small gaps
- Teeth that moved after braces because a retainer was not worn – see also second-round orthodontics
- Adults who want a nearly invisible, removable option for a simple case
For larger movements or bite problems, Invisalign or fixed braces may be more suitable.
Price
The i-liner price depends on how many aligners your case needs and is confirmed after an examination and 3D scan. Prices do not include the 3D scan and X-rays (THB 4,900).

At La Posh, clear aligners use the i-liner brand from Italy.
Getting ready for your first aligners
- You may feel tightness or mild soreness for the first 2–3 days, so plan a lighter schedule if you can
- Have soft food ready, such as yoghurt or rice porridge, and take pain relief if needed
- Speech may feel slightly different at first, so avoid scheduling important presentations on day one
