Many people researching Invisalign find themselves pausing at the Invisalign cost.
But what actually determines the outcome isn’t the price list — it’s the treatment plan.
It’s easy to assume clear aligners will line up your teeth perfectly on their own, but in practice, the clinician’s careful adjustments matter far more.
This article walks through an actual Invisalign case at a Dongdaemun-gu dental clinic, covering how ClinCheck works and where it falls short, the posterior molar movement stage, TAD screw use, and how the final bite is completed.
We’ll also cover the key treatment-planning factors worth checking alongside the Invisalign cost itself.
How Does Invisalign ClinCheck Actually Move Your Teeth?
ClinCheck isn’t a device that moves teeth on its own — it’s a planning tool that calculates and previews the sequence of tooth movement in advance.
ClinCheck is Invisalign’s proprietary software that uses 3D simulation to map out the direction and order of tooth movement before treatment begins.
Many people visiting a Dongdaemun-gu dental clinic assume this software alone produces a perfect result.
In reality, the clinician’s role — adjusting the direction and sequence of movement based on the patient’s dental arch, skeletal structure, and bite — matters far more.
✔ ClinCheck is a planning tool, not a device that guarantees results.
✔ How the teeth actually move depends on how carefully the clinician refines the digital plan.
What Should You Watch Out for in the Digital Setup?
If front teeth are aligned too quickly without enough space, they can end up protruding forward.
To reduce this risk, the treatment plan needs to be tailored to the patient’s current dental condition.
⚠ Rushing front-tooth alignment without adequate space can lead to protrusion.
⚠ A detailed treatment plan tailored to the current dental condition must be in place.
Why Are Molars Moved Before Front Teeth in Posterior Movement?
Aligning the front teeth first without enough space can push them forward, so molars are moved backward first to create room.
Posterior molar movement is the process of shifting the molars backward in sequence to create space for the front teeth to align.
When teeth are crowded or protruding without adequate space, aligning them first can push the front teeth outward.
That’s why, depending on the patient’s condition, a Dongdaemun-gu dental clinic may move the molars first for roughly the first 5 months.
Even if the front teeth don’t show much change during this period, it doesn’t mean treatment is falling behind.
- Create space through posterior molar movement
- Align crowded or protruding teeth using the newly created space
- Adjust the bite between front teeth and molars
✅ It reduces the risk of front-tooth protrusion caused by insufficient space.
✅ It creates room for crowded or protruding teeth to align naturally.
Once enough space has been created, front-tooth alignment begins in earnest.
This is also why the timing of visible front-tooth change varies across different Invisalign patient experiences — it comes down to differences in the tooth-movement sequence.
When and Why Are TAD Screws and Refinement Needed?
After the molars are moved backward, a step may be needed to keep them from drifting forward again.
A TAD (Temporary Anchorage Device) screw is a temporary fixation device that holds the molars in place while helping move the front teeth.
Depending on the patient’s condition, an orthodontic screw may be used as an anchorage point to keep the molars stable while the front teeth continue moving.
Once the teeth are aligned, the midline and molar occlusion are checked, and refinement is used if needed to fine-tune the bite.
✔ Screws aren’t used for every patient — they’re applied selectively based on the amount of movement and the bite condition.
✔ Refinement is an additional step to fine-tune the final bite, so it’s worth confirming in advance whether it’s included in the cost.
What’s the Timeline and Bite Change at Each Treatment Stage?
| Treatment Stage | Duration | Key Change |
|---|---|---|
| Stage 1: Molar Movement | About 5 months | Space created through posterior movement |
| Stage 2: Front-Tooth Alignment | About 8 months | TAD screw use; alignment of crowded/protruding teeth |
| Stage 3: Bite Adjustment | Total: Month 13 | Bite finalized through refinement |
※ Treatment duration and process may vary depending on each patient’s dental arch and bite condition.
What Else Should You Check Besides the Invisalign Cost?
Invisalign cost shouldn’t be judged by the price of the aligners alone — it should factor in the treatment plan and any follow-up adjustments.
When researching a Dongdaemun-gu dental clinic, it’s worth checking not just cost or convenience, but whether the clinic carefully refines the treatment plan and manages the bite through to completion.
In particular, ask in advance whether additional devices like TAD screws or refinement are included in the cost.
✅ Does the clinic adjust the ClinCheck simulation to match your actual dental condition?
✅ Is an early-stage plan in place, such as posterior molar movement?
✅ Are additional devices like TAD screws included in the cost?
✅ Is refinement billed separately or included?
Asking these questions during your initial consultation can help you compare treatment plans more thoroughly.

Frequently Asked Questions
1. Why don’t I see front-tooth changes right away?
Because the molars are moved first to create space and prevent the front teeth from being pushed forward. Front-tooth alignment begins in earnest afterward.
2. Does the Invisalign cost include additional devices?
Depending on how the teeth move, refinement may be needed as an additional step. When checking the cost, it’s a good idea to also confirm whether additional devices are included.
3. Are TAD screws needed for every Invisalign treatment?
No. They’re used selectively, only when needed based on the amount of tooth movement and the bite condition.
4. What should I check when choosing a Dongdaemun-gu dental clinic?
Rather than comparing reviews alone, it’s worth checking whether the clinic adjusts the 3D simulation to your actual dental condition and carefully manages the bite through to the final result.
