An Orthodontic Guide to Braceless Treatment from Dr. Begüm Ulaşan

Many people who want to straighten their teeth are no longer limited to traditional braces treatment. Especially in recent years, terms like clear aligner, aligner, and Invisalign have become very common. However, this abundance of terminology also brings up several questions:

  1. What exactly is a clear aligner?
  2. What does "Align / aligner" mean?
  3. What is Invisalign, and how is it different from other clear aligners?
  4. Is clear aligner suitable for every case, or are traditional braces necessary in some situations?
  5. Who plans these treatments, and which specialists should one trust?

As an orthodontist in Bursa, Dr. Begüm Ulaşan, who provides both classic braces and Invisalign and other clear aligner treatments under the umbrella of Milim Dental, frequently hears these questions from her patients. In this article, we will thoroughly address the clear aligner – Align – Invisalign trio from her expert perspective, providing a clear and detailed explanation.

1. What is a Clear Aligner?

A clear aligner is a thin, transparent, and removable custom-made mold that sits over the teeth, used to straighten them. These appliances, generally called "aligners" in English, are:

  1. Custom-made based on the 3D digital measurement of the patient's teeth.
  2. Each aligner is designed to move the teeth incrementally in a specific direction.
  3. The teeth are gradually brought to the targeted position by switching the aligners in a series.

The difference from traditional braces:

  1. No brackets are bonded to the teeth.
  2. No metal wires pass through them.
  3. They can be removed for eating, drinking, and brushing.
  4. When worn, they are almost unnoticeable from a distance, making them highly advantageous aesthetically.

This system, frequently used by orthodontists like Dr. Begüm Ulaşan in Bursa, is highly popular among adult and young patients who do not want visible braces in their professional or social lives.

2. What is Align / Aligner?

The word "Align" means to bring into correct relation or adjustment. In the field of orthodontics, "aligner" is:

The general term for the clear orthodontic appliances used to align the teeth.

Therefore:

  1. "Align" or "aligner" is not a brand name.
  2. Invisalign, ClearCorrect, other clear aligner systems, and even some in-house clinic-produced appliances all fall under the aligner category.

In everyday use:

  1. When patients say, "I want Align treatment" or "I want to use Align," they are actually referring to braceless orthodontics, i.e., clear aligner treatment.

Orthodontist Dr. Begüm Ulaşan first answers this question when planning a case:

"Can I correct this patient's teeth more healthily, more controllably, and more permanently with an aligner (clear tray), or with traditional braces?"

Because while Align/clear aligner technology has advanced significantly, it is not the only option for every case. In some situations, braces may still be the most reliable method. The ideal approach is to conduct an individual assessment for every patient.

3. What is Invisalign?

Invisalign is one of the most well-known and widely used branded clear aligner systems globally.

Key Features:

  1. Developed by the US-based company, Align Technology.
  2. It has an advanced software infrastructure supported by digital data collected from millions of cases.
  3. Tooth movement is planned by simulating the process step-by-step in a computer environment.
  4. Clear aligners are produced in a series according to this plan.

Invisalign’s advantages:

  1. The orthodontist can view the entire treatment process in detail digitally.
  2. The amount and direction of tooth movement at each aligner stage are planned millimetrically.
  3. It is a powerful option, especially for mild to moderate crowding, certain bite problems, and aesthetic corrections.

However, there is a very important point here:

Invisalign is a "tool," but the "brain" of the treatment is still the orthodontist.

When using the Invisalign system, Dr. Begüm Ulaşan in Bursa:

  1. First performs a detailed examination and analyzes the tooth-jaw relationship with X-rays and 3D scans.
  2. Guides the Invisalign software in accordance with orthodontic principles.
  3. Creates a treatment plan where she decides which tooth will move, in what order, and by how much.

In short, Invisalign is not a "magic tray" that treats itself; it is a tool that yields successful results when used intelligently by a skilled orthodontist.

4. How Does Clear Aligner Treatment Work?

The fundamental concept behind clear aligner / Align / Invisalign treatment is the same. Let's summarize the steps:

4.1. Initial Examination and Assessment

The orthodontist, for example, Dr. Begüm Ulaşan, will:

  1. Perform an intraoral examination.
  2. Examine the tooth-jaw relationship using panoramic X-rays, possibly cephalometric films, and 3D scans.
  3. Evaluate the severity of the crowding, jaw structure, gum health, and joint condition.
  4. Decide whether the case will be better resolved with a clear aligner, classic braces, or a combination of both.

4.2. Digital Impressions (Intraoral Scanning)

In clear aligner treatment, most clinics now use digital scanners instead of traditional putty-based impressions.

  1. Your teeth are scanned in 3D using an intraoral scanner.
  2. The digital model of your teeth is created in the computer environment from this scan result.
  3. Patients generally find this stage very comfortable, which is a major advantage for those with a gag reflex.

4.3. Digital Planning

The orthodontist:

  1. Views the current status of your teeth on the digital model.
  2. Determines the target ideal alignment.
  3. Plans the steps between these two states in the computer environment.

In systems like Invisalign:

  1. Each aligner stage is simulated through the software.
  2. This provides a preview of how the teeth will look at the end of the treatment, before it even begins.

During this process, Dr. Begüm Ulaşan aims for a functionally correct bite, not just an aesthetic one. The goal is not merely to "line up the teeth"; chewing and joint health are also taken into consideration.

4.4. Aligner Manufacturing and Delivery

Once the plan is approved:

  1. A series of clear aligners are manufactured to gradually move your teeth.
  2. The aligners are usually delivered to you numbered.
  3. The first aligner is placed in the mouth, and detailed instructions for use are provided.

4.5. Usage Process

In general:

  1. Each aligner is worn for approximately 7–10 days (14 days in some systems).
  2. They must be worn for 20–22 hours a day.
  3. They are removed only for eating, drinking hot beverages, and brushing teeth.

During control appointments, orthodontist Dr. Begüm Ulaşan will:

  1. Check if the teeth are moving in the planned direction.
  2. Adjust the aligner change rate and duration according to the clinical progress.
  3. Make the movements more controlled with additional elastics or small attachments (tiny clear bumps bonded to the tooth surface) if necessary.

5. Clear Aligner vs. Braces Comparison

One of the most important questions in patients' minds is:

"Can I get a clear aligner (Align / Invisalign) instead of braces?"

The answer to this question must be given by an orthodontist for accurate planning. However, a general comparison is possible:

FeatureClear Aligner (Align / Invisalign)Braces (Fixed Appliance)
AestheticsAlmost invisible when viewed from a distance. Highly advantageous for adults who want invisible treatment.More noticeable. Aesthetic (clear/ceramic) brackets are less visible but not as invisible as clear aligners.
ComfortLess friction on the soft tissues of the mouth. Since they are removable, issues like broken wires during meals are avoided.Can cause initial irritation to the lips and cheeks. This lessens with special wax and adaptation over time.
ComplianceCritical: Success depends entirely on wearing them consistently for 20-22 hours/day. Inconsistent use ruins the treatment.Since they are fixed, the patient cannot remove them. Therefore, treatment is not dependent on the user "forgetting."
Case SuitabilityExcellent option for mild to moderate crowding, certain bite problems, and aesthetic corrections. Can be used for more difficult cases with advancing technology, but may not be suitable for every case.Still the stronger and more highly controlled treatment option for very severe crowding, advanced skeletal discrepancies, excessive rotations, and complicated extraction cases.

Dr. Begüm Ulaşan in Bursa prefers to objectively explain both clear aligner (Align, Invisalign) and braces options to every patient, determining together which method is more suitable.

6. Who is Suitable for Clear Aligner (Align, Invisalign) Treatment?

In general, the following groups can greatly benefit from clear aligner treatment:

  1. Adults with Mild to Moderate Crowding: Crookedness, slight crowding, or spacing in the front teeth.
  2. Individuals with High Aesthetic Concerns: People who are constantly communicating in their professional lives and want an invisible solution.
  3. Aesthetic-Conscious Adolescents: Young patients active in fields like photography, video, stage, music, or acting.
  4. Patients who experienced Relapse after Previous Orthodontic Treatment: In patients who didn't use retainers after their initial treatment or lost them, causing teeth to shift slightly back, clear aligners can be a very practical solution for a second correction.
  5. Adults who Reject Braces but Want Healthy Teeth Alignment.

Naturally, as with every patient, the final word belongs to the orthodontic specialist.

In her examinations at Milim Dental in Bursa, Dr. Begüm Ulaşan approaches every patient with the philosophy: "Let's use clear aligners for the part we can correct with them, and openly discuss the necessity of braces if needed."

7. Why is Doctor Selection Important in Clear Aligner Treatment?

In advertising often seen online, clear aligners are sometimes marketed as if "a dentist isn't necessary." This is an extremely false and risky perception.

Moving teeth is not just a matter of "pushing and pulling."

Many factors must be considered, such as the jaw joint, chewing muscles, gum health, and the position of the roots within the bone.

Thanks to the planning done by an orthodontic specialist like Dr. Begüm Ulaşan:

  1. Teeth are moved in the correct sequence and amount.
  2. The risk of excessive root resorption (root shortening) is minimized.
  3. Chewing function and joint health are preserved.
  4. Smile aesthetics are designed to be harmonious with the facial profile.

In summary: The clear aligner (Align, Invisalign) is a tool, but the knowledge and experience of the orthodontist are what truly make the treatment safe and effective.

8. Frequently Asked Questions

QuestionAnswer
Do clear aligners and braces do the same job?In many cases, yes, they serve the same goal; however, in some severe cases, braces offer a more controlled and powerful treatment. Your orthodontist should decide which treatment is right for you.
Is Invisalign different from other clear aligners?As a brand, Invisalign has extensive case data and an advanced software infrastructure. However, the result still depends on the experience of the orthodontist who does the planning. Other Align systems can also yield very successful results in the right hands.
Will my teeth hurt a lot during clear aligner treatment?There may be a mild to moderate pressure sensation for a few days with each aligner change. This indicates that the teeth are moving. Most patients manage this period comfortably with simple pain relievers.
How many hours a day do I need to wear the aligners?The standard recommendation is 20–22 hours. Wearing them for less time will prevent the desired tooth movement and prolong the treatment.
Who can I see in Bursa for clear aligner (Align, Invisalign) treatment?Orthodontic treatments should ideally be planned and monitored by an orthodontic specialist. Dr. Begüm Ulaşan, an orthodontist in Bursa under Milim Dental, offers both clear aligner (Align, Invisalign) and braces options, providing personalized solutions to her patients.
