Clear aligners are removable trays that move teeth gradually; they may suit some cases, not all. At Dr. Türker Clinic in Istanbul, the orthodontist Assoc. Prof. Dr. Elif Dilara Arslan handles this treatment. Duration varies with the case, and a retainer is generally needed afterward.
Clear aligners are removable trays, changed in stages, that move teeth gradually according to a digital plan. They may suit some crowding, gaps or bite discrepancies, but not every case. Treatment time varies with the case and can be estimated only after an examination. At Dr. Türker Clinic in Nişantaşı, Istanbul, this treatment is handled by the orthodontist Assoc. Prof. Dr. Elif Dilara Arslan, and the follow-up and the retainer matter as much as the trays.
This guide describes the technique in general terms and is not tied to any one manufacturer. It is written for people considering orthodontic treatment in Istanbul, particularly readers in the UK, Ireland, the US and Canada who would be traveling for it. If your project is mainly about reshaping your smile with veneers, read veneers in Turkey: risks, irreversibility and alternatives first, which lists orthodontics among the options to weigh before any tooth is prepared.
What clear aligners are
Clear aligner treatment uses a series of clear plastic trays made from a scan or digital impression of your teeth. Each tray applies limited pressure. You move on to the next one in stages, and the teeth shift gradually toward the planned position. The trays are removable, which makes brushing easier, but they work only while they are in your mouth.
They are discreet, but they are not a cosmetic accessory: this is a full orthodontic treatment that moves teeth within the bone and needs follow-up.
The plan is simulated before the first tray is made. Assoc. Prof. Dr. Arslan uses a 3D scan and planning software to simulate the tooth movements step by step. A simulation is a proposal: teeth do not always follow the planned path exactly, and the orthodontist adjusts the plan during treatment.
Which patients they may suit
The clinic presents this treatment as suited to teenagers and adults, to correct crowding, gaps and certain bite discrepancies. The table below places the common situations; only an examination can place yours.
| Situation | Clear aligners | Also to consider |
|---|---|---|
| Mild to moderate crowding | Often worth discussing | A fixed appliance (braces) if the movement is more complex |
| Gaps between teeth | To discuss, depending on the cause and the goal | An aesthetic restoration, once its limits have been examined |
| Moderate bite discrepancy | To be assessed by the orthodontist | A fixed appliance |
| Complex movements, difficult anchorage | Sometimes not enough on their own | A fixed appliance, miniscrews (SemiOSS system) |
| Marked jaw discrepancy | Do not correct the bone on their own | Orthodontics preparing for orthognathic surgery |
| Child still growing | Depends on age and case | Dentofacial orthopedics, which guides growth |
What has to be settled before starting
The condition of your mouth decides the starting point. Untreated decay or gum disease is dealt with first, because moving teeth on inflamed tissue exposes you to complications. Also mention any teeth grinding (bruxism) or jaw discomfort: our guide to TMJ disorders explains how these are assessed.
When a project combines several treatments (teeth to replace, veneers, gum correction, surgery), the order is discussed among the specialists. Orthodontics often comes first, because it changes the position of the teeth on which restorations will rest. Dr. Türker Clinic describes its three disciplines, oral and maxillofacial surgery, aesthetic dentistry and orthodontics, as working under one roof on a shared plan.
If what bothers you is a gummy smile, orthodontics is not always the answer: see gingivectomy vs crown lengthening.
When the jaw is involved: orthodontics and surgery
Orthodontics moves teeth, not jaws. When the mismatch between the jaws is marked, aligners alone do not correct it, and orthognathic (jaw) surgery may be discussed. Cases of this kind are generally coordinated with orthodontics: Assoc. Prof. Dr. Arslan plans the tooth alignment for the patients concerned, in coordination with Assoc. Prof. Dr. Türker Yücesoy, the clinic’s oral and maxillofacial surgeon. The type of appliance used for this preparation is decided case by case. Our guide to orthognathic jaw surgery in Istanbul covers the indications and the stay.
How treatment works under the orthodontist’s supervision
Aligners are not something you simply order: an orthodontist plans them, monitors them and adjusts them. The main steps are these.
- Examination and records. A clinical examination, photographs, X-rays and a digital impression, with 3D imaging when the case requires it. The plan is never set from a description alone. Our guide to CBCT and 3D planning explains what this imaging adds, even though it is written around implants.
- Goals and alternatives. The orthodontist explains what can be corrected, what will not be, and compares aligners, a fixed appliance and other options.
- Digital plan. A step-by-step simulation, reviewed with you before the trays are made.
- Wearing the trays. Following the orthodontist’s instructions, for most of the day, with careful brushing before putting them back in. How consistently you wear them determines how treatment progresses.
- Check-ups. The orthodontist checks that the teeth are following the plan, adjusts it and, if needed, plans new trays. If a tray is lost or stops fitting, tell the orthodontist promptly, with a photo if possible, before deciding on your own to skip or resume a step; the right instruction depends on your case.
- End of the active phase and retention. Once the teeth reach the planned position, the active phase ends and a retainer takes over to help keep that position (see the retention section below).
The treatment is planned and supervised by Assoc. Prof. Dr. Elif Dilara Arslan, an associate professor of orthodontics whose practice covers clear aligners, fixed appliances, miniscrew anchorage (the SemiOSS system) and orthognathic preparation. Her profile is on the page for Assoc. Prof. Dr. Elif Dilara Arslan. The clinic offers consultations in Turkish, English and French; her profile lists Turkish and English, and a coordinator handles organization and translation.
How long does it take? Why there is no reliable number before an examination
This guide deliberately gives no duration. It depends on the case, and only an examination followed by the digital plan makes it possible to discuss one. It varies notably with
- the extent of the movements and the number of teeth involved;
- how consistently the trays are worn;
- the biological response of your teeth and gums;
- the adjustments needed along the way;
- the retention phase that follows the active treatment.
If a duration is quoted from a few photos, with no examination, ask what it is based on. Ask for a written estimate, with the conditions that could change it.
Retention: the phase that helps keep the new position
Once teeth are aligned they can move again. A retainer, fixed or removable, aims to stabilize the position you have reached. It is part of the treatment, not a comfort option. The orthodontist specifies the type, how long to wear it and the check-ups. Settle from the start who will replace a lost or broken retainer, because that can happen once you are home, far from the clinic.
Following treatment from abroad
Aligner treatment runs over a variable period, with check-ups. For someone living in the UK, Ireland, the US or Canada, that is a central practical question. Depending on the case, the orthodontist may decide that remote follow-up is not reasonable; it is better to learn that before you book a flight to Turkey. If a realistic follow-up cannot be arranged, an orthodontist near home remains a sound option.
Before committing, ask these questions and get the answers in writing
- [ ] Which orthodontist is responsible for the plan, and who answers between check-ups?
- [ ] How many check-ups are in person, and which can be done remotely (photos, video call)?
- [ ] What should I do if a tray is lost, broken or stops fitting?
- [ ] Which local orthodontist would agree to step in, bearing in mind that a colleague may refuse to take over a treatment they did not plan?
- [ ] Will I receive the digital plan, the starting photos and X-rays, and the references of the trays?
- [ ] Which retainer is planned, for how long, and who replaces it?
- [ ] What does the written quote cover: trays, any adjustments, the retainer?
- [ ] In which language are the consultation and the consent held?
For organizing the trip, see preparing a dental trip to Turkey, which is written mainly around implants but covers the practical steps. To compare two orthodontic plans, the method in our guide to a second opinion, written for implants, applies as well: same file, same questions.
Limits, alternatives and when to postpone
Limits to know
- Aligners do not suit every movement, and the simulation is not a promise of result.
- They depend on you: a tray left in its case moves nothing.
- Pressure or discomfort can appear when you start wearing them or at each change of tray.
- They do not replace treatment of decay or gum disease, a night guard, or jaw surgery.
- An occlusal splint (night guard) for grinding or a jaw joint disorder is not an aligner: it protects or relieves, and does not move teeth.
Alternatives to examine
- Fixed appliance (braces) (metal, ceramic or self-ligating brackets): acts continuously and can control some movements finely.
- Miniscrew anchorage (SemiOSS system): may help with complex movements.
- Aesthetic restoration (veneers, bonding): answers a request about shape, with the reservations set out in the veneers guide linked above.
- Doing nothing: sometimes reasonable when the discomfort is slight and your expectations are not yet precise; the orthodontist can discuss it with you.
When to hold off on a decision
Shared decision-making means understanding the options and their limits before committing. It is reasonable to wait, or to ask for a second opinion, when
- decay, gum disease or jaw pain has not been assessed;
- the orthodontist has not explained what the treatment will not correct;
- follow-up after you go home has not been organized in a realistic way;
- a plan for surgery, implants or veneers is not yet settled, and the order of treatment is still unclear.

This article rests on general principles of orthodontics and on the clinic’s own presentation. It quotes no figures from studies and does not replace the opinion of an orthodontist who has examined you.
Getting a preliminary opinion
If you are unsure between clear aligners, a fixed appliance or another option, you can send the clinic front and side photographs of your smile, a recent panoramic X-ray (or a CBCT if you have one) and the goal you are pursuing. You can reach the team on WhatsApp at +90 531 818 02 87 or through the contact page; see that page for current opening hours.
A remote assessment does not replace an examination, and nothing obliges you to decide after a first exchange.
Frequently asked questions
Does Dr. Türker Clinic offer clear aligners in Istanbul?
Yes. At Dr. Türker Clinic in Nişantaşı, clear aligner treatment is handled by the orthodontist Assoc. Prof. Dr. Elif Dilara Arslan, after an examination and a digital plan. It does not suit every case: the orthodontist confirms the indication and the alternatives after examining you, and never sets a plan from a description alone.
Can clear aligners fix every kind of crowding or bite problem?
No. They may suit some crowding, gaps or bite discrepancies in teenagers and adults. A complex movement may call for a fixed appliance or miniscrew anchorage, and a marked jaw discrepancy may point to orthognathic surgery. Untreated decay or gum disease is dealt with first.
Clear aligners or braces: which is right for me?
It depends on the movement needed, not only on looks. Aligners are removable and discreet but rely on regular wear. A fixed appliance, whether metal, ceramic or self-ligating, works continuously and can control some movements finely. The orthodontist compares both on your file after an examination.
How long do clear aligners take?
It varies with the case: the extent of the movement, your goals, how consistently the trays are worn, how your teeth respond and any adjustments along the way. It can be estimated only after an examination and a digital plan, never from a few photos. Ask for a written estimate and the reasons it could change.
Do I need a retainer after clear aligners?
Generally, yes. Once teeth are aligned they can move again, and a retainer, fixed or removable, helps keep the position. The orthodontist specifies the type, how long to wear it and the check-ups. Ask who replaces a lost or broken retainer, especially if you live far from the clinic.
Can I have clear aligner treatment if I live abroad?
It depends on the case and on how follow-up is organized. Treatment runs over a variable period with check-ups, so ask how many are in person, which can be remote, who answers between check-ups and which local orthodontist could help. If follow-up is not realistic, an orthodontist near home remains a sound option.
What should I do if a tray is lost or stops fitting?
Tell the orthodontist promptly, with a photo if possible, before deciding on your own to skip or resume a step. The right instruction depends on your case. Ask for it in writing before you leave, especially if you live abroad.
Is a night guard for grinding the same as a clear aligner?
No. Aligners move teeth according to an orthodontic plan. An occlusal splint, or night guard, protects the teeth or eases the jaw in grinding or a jaw joint disorder, without trying to move them. Tell the orthodontist about any grinding or jaw pain before starting.
This guide informs; it does not replace a consultation or an individual diagnosis. Every case needs a clinical examination and 3D imaging.
