Short answer: A clear aligner transfer is the handover of ongoing orthodontic treatment to a new doctor because of a move or another reason. In Invisalign treatment, this is done by the previous and new doctors transferring the case record through the Invisalign system. The new doctor examines your mouth, takes a digital scan, updates the plan if necessary, and treatment continues from where it left off.
Orthodontic treatment often takes a year or longer, and life doesn't stop during that time: jobs change, university starts in another city, families move. In such situations, the most frequently asked question is what will happen to the unfinished treatment. A clear aligner transfer is the process that meets exactly this need, allowing ongoing treatment to be taken over by a new doctor. When planned correctly, treatment can largely continue from where it left off; however, certain records and communication need to be complete.
In this article we explain when a transfer comes up, which documents need to be prepared beforehand, how the new doctor takes over the treatment and the common hiccups in the process. If you are curious about the general treatment flow, you can first take a look at our clear aligner treatment process page.
What is a clear aligner transfer, and when is it needed?
A treatment transfer is the formal, documented handover of responsibility for a patient's orthodontic treatment from one doctor to another. With clear aligners, this doesn't simply mean the patient taking the aligners they have and going to another clinic; the treatment plan, digital models and production records are also transferred to the new doctor.
A transfer is most often needed in the following situations:
- A permanent move to another city or country
- University studies, military service or a long-term work assignment
- The doctor's retirement or a change of clinic
- The patient's own wish to continue with a different doctor
A transfer is generally not needed for short trips. Your doctor can give you several sets of aligners and plan remote follow-up. Once a move is confirmed, not leaving the transfer to the last week and, if possible, discussing it a few weeks in advance makes things easier.
Which records are needed before a transfer?
Before a transfer, records showing the starting and current state of treatment are needed so that the new doctor can evaluate the treatment correctly. The more complete these records are, the smoother the handover.
What to request from your current doctor
- Initial records: Pre-treatment intraoral and facial photos, panoramic and, if needed, cephalometric X-rays
- Treatment plan summary: The planned tooth movements, the total number of aligners and which aligner you are currently on
- Additional procedures: The location of attachments bonded to the teeth, the amounts of interproximal reduction (IPR) between teeth if done, and any elastics used
- General health and dental history: Important information such as fillings, root canal treatments and extractions
What the patient should bring along
Any unused aligners you still have, the aligner you are currently wearing and the previous aligner must be kept. If an aligner is lost or broken, the previous set can be used temporarily. The numbers on the aligner packaging also help the new doctor quickly understand which stage you are at.
The new doctor taking over the treatment
Before taking over the treatment, the new doctor always carries out their own examination, because they are now the person responsible for the treatment. This examination evaluates how well the teeth fit the aligners, the integrity of the attachments, gum and bone health, and how far the plan has progressed.
In Invisalign treatment, the transfer is a process carried out within the Invisalign system. The previous doctor releases the case for transfer, the new clinic takes the case into its own account and can access the digital treatment plan. This way, the new doctor can make decisions by seeing the initial digital models and the planned movements. Whether the transfer is accepted and under what conditions it will proceed are discussed with the doctor after the examination.
At this stage, the following should be clearly explained to the patient:
- Whether it is appropriate to continue with the current plan
- Whether additional aligners or a plan revision are needed
- How often check-ups will be and the appointment schedule
- Fees; this is provided in writing after the examination and planning
Aligner production and updating the plan
After the transfer, the plan is often either continued as is or renewed according to the current situation. If the teeth have progressed according to plan, it is possible to continue with the remaining aligners. However, if aligner wear was disrupted during the move, some teeth may have drifted from their expected positions; in this case, the aligners don't seat or don't fully contact the teeth.
When such a mismatch is noticed, the new doctor takes an up-to-date digital impression with an intraoral scanner. The plan is rearranged based on this scan and new aligners are produced. If attachments have come off or need to be repositioned, they are bonded again. This kind of mid-course correction is a normal step in orthodontics and does not mean the treatment has failed.
Updating the plan may extend the total treatment time somewhat. How much longer it will take varies from person to person and is estimated by the doctor after the examination.
Common problems in transfers
The most common problems in transfers are incomplete records, disrupted aligner wear and breakdowns in communication. Most of these can be prevented by planning ahead.
- Records arriving late: If communication with the previous clinic is delayed, the new doctor may have to take new records. Requesting copies before you move reduces this risk.
- Stopping aligner wear: Skipping aligner wear for a few weeks in the rush of moving can cause teeth to move back. The rule of wearing them 20–22 hours a day also applies during a move.
- Losing aligners: Mixed-up or lost cases are common. Carrying your aligners in a separate, labeled bag helps.
- Differences in expectations: Each doctor's treatment approach may be slightly different. It is important to openly ask about and understand any small changes the new doctor suggests.
- Forgetting the retention phase: The retention (retainer) plan to be used after treatment ends should also be discussed as part of the transfer.

How should you prepare before moving?
The most helpful thing to do before moving is an open planning conversation with your current doctor. In this conversation you can find out what stage your treatment is at, how many aligners are left and within what time frame you need to be examined in the new city.
A short checklist for preparation could be:
- Schedule your last check-up a few weeks before your moving date.
- Request digital copies of your records and keep them in a safe place.
- Book an appointment in advance with an orthodontist who provides Invisalign in your new city.
- Pack your remaining aligners in order and labeled; don't throw away the previous aligner.
- Note down who you will contact in situations such as an attachment coming off, a broken aligner or pain.
These steps help the transition between the two doctors go smoothly without any gaps. Especially with teenage patients, since school and the pace of moving can disrupt aligner wear, it is helpful for the family to keep a closer eye on things during this period.
What should you do if you're moving to Ankara?
If you have moved to Ankara during your treatment, or if you need to leave Ankara, bringing your aligners and the records you have and scheduling an orthodontic examination is a sufficient start. At our clinic in Park Oran Ofis in Oran, Çankaya, to take over treatments in progress with Invisalign, the current situation is examined first, and then the plan for continuing is discussed together. If you'd like information about options in the area, you can review our clear aligners in Ankara page.
Frequently asked questions
If I move to another city, will my clear aligner treatment be left unfinished?
No, in most cases the treatment can be continued by handing it over to a new doctor. In Invisalign treatment, the case record is transferred to the new clinic and the new doctor takes over the plan after an examination. Preparing the records in advance makes the process easier.
Can I take a break from wearing aligners during the transfer?
Taking a break is not recommended. If aligners are not worn 20–22 hours a day, the teeth may drift from their planned positions and the next aligners may not fit. Continuing with the aligner your doctor told you to wear until your new examination is the safest way.
Can the new doctor change the treatment plan?
Yes, if necessary. The new doctor examines the current situation; if the plan is suitable it continues as is, and if not, a new digital scan is taken and the plan is revised. This decision is made based on the intraoral findings.
How are fees determined in a transfer?
Fees vary depending on the remaining treatment needs and whether the plan will be updated. For this reason, they are provided in writing after the examination and planning.
