Spark Clear Aligners are removable clear aligners made by Ormco (USA) from TruGEN™ material. They are worn about 22 hours a day and changed every 1–2 weeks according to your orthodontist’s plan.[5] Treatment usually takes about 6 months to 3 years, depending on the case. At Smile & Co. Dental Clinic (Phaya Thai, Bangkok, Thailand) there are three packages: Spark 10 at THB 60,000, Spark 20 at THB 90,000 and Spark Advanced at THB 135,000. Prices include X-rays, digital scans, attachments, interproximal reduction (IPR), refinement aligners within the package terms and one pair of standard clear retainers.

What Are Spark Clear Aligners?
Clear aligner treatment straightens teeth with a series of custom-made clear plastic trays. Each tray moves the teeth a small step along a plan that your orthodontist designs on a computer. When the whole series has been worn, the teeth reach their planned positions. The trays are removed for eating and brushing.
Spark is a clear aligner system from Ormco, the same company that makes Damon braces. The orthodontist plans every tooth movement in the Spark Approver software and decides where attachments or elastics are needed. Research reviews show that clear aligners align and level crowded teeth well, while fixed braces control root angulation better, and some movements, such as rotating rounded teeth or extrusion, remain less predictable.[1][2]
Research on Spark itself is still limited. In a randomized trial of 80 patients, attachments placed with the Spark template stayed on at template removal in 87.5% of patients,[6] and a study of 100 adults treated with four aligner brands, including Spark, found that about 57–60% of the planned arch expansion was achieved after the first series of aligners, with similar results across brands.[7] This is why your orthodontist checks progress at every visit and may order refinement aligners, within the package terms, when teeth have not yet reached the planned position.

Key Features of Spark Aligners
- Less noticeable: the clear trays fit closely, so they are less visible than fixed braces.
- Removable: take them out to eat, brush and floss, so you can keep your teeth clean as usual.
- TruGEN™ material: the manufacturer states it is designed for sustained force, clarity and low staining.[5]
- Digital planning: your orthodontist fine-tunes each movement in the software, and you can see a simulation before you start.
- Several packages: from up to 10 aligners to unlimited aligners for 5 years, matched to how complex your case is.
Spark Aligner Features and Auxiliaries
Besides the clear trays, your orthodontist may add auxiliaries to your plan so the aligners can grip the teeth and apply force in the right direction. Every case is different, and not every feature is needed.
- Attachments: small tooth-colored bumps bonded to the teeth. They give the aligner something to push against and help with harder movements, such as rotations or moving teeth up or down. They are placed with a clear template and polished off at the end of treatment.
- Hooks: hooks built into the aligner for elastics, for example to correct an overbite or underbite.
- Cutouts: openings at the aligner edge so elastics can attach to buttons on the teeth.
- Bite ramps and bite turbos: small raised areas on the aligner that help open a deep bite.
- Pontics: a tooth-shaped area in the aligner that fills a gap from a missing tooth while the space is closed or a replacement is planned.
- Eruption tabs: for children whose adult teeth are still coming in, the aligner leaves room for them to erupt.
Feature names and designs are manufacturer information.[8] Your orthodontist chooses what your plan needs.
Who Are Spark Aligners Suitable For?
- People with crowded teeth, gaps, mildly protruding teeth, or teeth that have shifted after previous braces
- People who prefer a less visible option, such as working professionals
- People who can wear the aligners about 22 hours a day and keep them safe when removed
- Children and teenagers: the manufacturer states Spark is designed for children with mixed (baby and adult) teeth as well as teens. Your orthodontist will assess whether it suits your child.
Good to know: gum disease must be treated before starting. For very complex cases, such as large vertical movements or treatment with jaw surgery, your orthodontist may recommend fixed braces instead, or a combination.
Spark Treatment Steps
- Consultation with a specialist orthodontist to check your teeth, gums and bite and discuss your goals.
- X-rays and a digital scan with the iTero Lumina scanner instead of traditional impressions.
- Digital treatment planning: your orthodontist designs each tooth movement in the Spark Approver software and shows you a simulation before you start.
- Attachments (if your plan needs them): small tooth-colored bumps that help the aligners grip the teeth. You then receive your first aligners.
- Wear each aligner about 22 hours a day and switch every 1–2 weeks as instructed. Check-ups with your orthodontist are about every 2–3 months to follow progress and collect your next aligners.
- Wear retainers after treatment to keep the teeth in place, as teeth tend to move back without them.[4]
How Much Do Spark Aligners Cost in Bangkok?
Prices at Smile & Co. Dental Clinic depend on the number of aligners. Your orthodontist will recommend a package after examining your teeth and planning your treatment.
| Package | Price | Aligners | Suitable for |
|---|---|---|---|
| Spark 10 | THB 60,000 | Up to 10 | Mild crowding or spacing, about 2–3 mm |
| Spark 20 | THB 90,000 | Up to 20 | Moderate crowding or spacing |
| Spark Advanced | THB 135,000 | Unlimited for 5 years | All levels of complexity, including bite correction |
- Included: X-rays, digital scans, attachments, interproximal reduction (IPR), refinement aligners within the package terms and one pair of standard clear retainers.
- Not included: other dental treatment that may be needed before or during treatment, such as scaling, fillings or extractions. Spark retainers are available separately at THB 6,000 per pair. A sterilization fee of THB 50 applies per visit.
- Orthodontist consultation fee: THB 500, fully deducted from the treatment cost when you start treatment.
- Installment payment options are available. Please ask the clinic about the terms.
- Spark 10 and Spark 20 cannot go beyond the number of aligners in the package, so your orthodontist chooses the right package when planning. Spark Advanced includes unlimited aligners for 5 years.
- Lost or broken aligners: THB 10,000 per new scan, and replacement aligners count toward the number of aligners in your package.

How Long Does Spark Treatment Take?
Spark treatment usually takes about 6 months to 3 years, depending on the complexity of the case, the number of aligners and how consistently they are worn. Mild crowding needs fewer aligners, while bite correction or extraction cases usually take longer. A clinical trial comparing 7-day and 14-day aligner changes found clinically similar accuracy,[3] so your orthodontist sets the change interval to suit your plan.
Spark vs Invisalign vs Fixed Braces
All three work well when matched to the right case, and no single option suits everyone. The clinic offers Spark, Invisalign and fixed braces, and your orthodontist will help you choose at your consultation. Treatment time depends on each case, so the figures are not a like-for-like comparison. Each option’s price also includes different items, and your orthodontist will explain the details before you start.
| Feature | Spark Clear Aligners | Invisalign | Fixed braces (metal) |
|---|---|---|---|
| Manufacturer | Ormco | Align Technology | Various |
| Type | Removable clear aligners | Removable clear aligners | Brackets bonded to the teeth |
| Wear | About 22 hours/day | About 22 hours/day | Fixed throughout treatment |
| Typical duration | 6 months–3 years | 6 months–3 years | 2–3 years |
| Price at the clinic | THB 60,000–135,000 | THB 70,000–160,000 | THB 39,000–48,000 |
| Watch out for | Requires wear discipline | Requires wear discipline | Harder to clean around brackets |

Living Abroad? How to Get Spark Aligners in Bangkok
Patients who live overseas can start Spark treatment at the clinic in two trips to Bangkok, followed by check-ups according to the treatment plan. Your orthodontist will first check whether your case is suitable for this approach.
- Trip 1: consultation and records. An exam with a specialist orthodontist, X-rays, a digital scan, and any dental work needed first, such as scaling or fillings.
- Review your plan. Your orthodontist plans the tooth movements in the Spark Approver software and may go through the plan and simulation with you online.
- Trip 2: receive your aligners. Attachments or other auxiliaries are placed as planned, and you receive your aligners and wearing instructions.
Trip 1 and Trip 2 are at least 1.5 months apart, to allow for planning and aligner manufacturing. After that, follow-up visits at the clinic are about every 6–12 months, depending on your plan. Wear the aligners consistently in between, and contact the clinic if you have any problems.
Caring for Your Teeth During Spark Treatment
- Wear the aligners about 22 hours a day, including at night. Remove them only to eat, to drink anything other than plain water, and to brush.
- Brush and floss before putting the aligners back in, so no food is trapped under them.
- Rinse the aligners in cool or room-temperature water and brush them gently. Avoid hot water, which can warp them.
- Always keep the aligners in their case when they are out. Do not wrap them in tissue, as they are easily thrown away.
- In the first 1–2 days of a new aligner, the teeth may feel tight. This is normal. Contact the clinic if the pain is strong or an aligner breaks.
- Keep your check-up and scaling appointments, and wear retainers as advised after treatment.[4]

About 22 hours a day, including at night. Remove them only to eat, to drink anything other than plain water, and to brush.
Yes. Remove them before drinking tea, coffee or anything other than plain water. Hot drinks can affect the aligner material, dark drinks can stain them, and sugar or acid can be trapped under the aligner against your teeth. Rinse or brush before putting them back in.
Teeth may not move as planned, and the next aligner may not fit well or may feel very tight. Treatment can take longer, and you may need a new scan for refinement aligners, which must stay within your package’s limits and terms. Wear them about 22 hours a day, every day.
