Why Are There Gaps Between My Teeth? Diastema Treatment with Clear Aligners in Nicosia

“My teeth have gaps between them.”

This is a phrase we often hear during orthodontic consultations, but it does not tell the same story for every patient. A gap between the front teeth, known as a diastema, may look similar from the outside, but there can be many different underlying causes.

One of the reasons this patient, who was evaluated by Dr. Yusuf Ozant at Ozant Dental Clinic, came to our clinic was the noticeable gap between the upper front teeth.

However, the first question in our treatment planning was not, “How can we close this gap?”

First, we needed to understand why the gap had developed.

Especially in diastema cases, simply moving the teeth closer together may not be enough. If the factors contributing to the formation or reopening of the gap are not properly evaluated, the teeth may separate again after orthodontic treatment.

What Was Causing the Gap Between the Front Teeth?

There is no single cause of gaps between the front teeth.

Teeth that are relatively small compared with the jaw, discrepancies in tooth size, missing teeth, tooth positions, bite relationships, and certain anatomical structures can all contribute to the development of a diastema.

In this case, the factor that drew our attention was the upper lip frenulum.

The attachment of this band of tissue, which extends from the inside of the upper lip to the gum, was located very close to the area between the front teeth. During the clinical evaluation, we considered that the structure and attachment of the frenulum could be contributing both to the formation of the midline gap and to its tendency to reopen after closure.

Therefore, the treatment plan for this patient could not focus solely on moving the teeth.

Orthodontic tooth movement, management of the frenulum, and post-treatment retention needed to be planned as a whole.

We Started Treatment with Clear Aligners

Following our consultation with the patient and a comprehensive orthodontic evaluation, we decided to proceed with clear aligner treatment.

The first stage of treatment was planned as a series of 20 aligners.

In clear aligner treatment, patient compliance is just as important as digital planning. Wearing the aligners for the recommended amount of time and following the prescribed change schedule are important parts of achieving the planned tooth movements.

Our patient showed very good compliance throughout this stage.

The aligners were worn regularly and changed once a week, allowing the patient to complete the first series of 20 aligners.

The teeth moved according to plan, and the gap between the front teeth—one of the patient’s main concerns at the beginning of treatment—was closed.

However, this case highlighted an important clinical point:

Closing a gap and keeping that gap closed are not the same thing.

Why Was the Timing of the Frenectomy Important?

One of the important stages of this patient’s treatment plan was a frenectomy involving the upper lip frenulum.

Because of the position of the frenulum, its potential influence on the treatment needed to be managed appropriately.

However, the planned frenectomy was delayed.

During this period, the midline gap that had been closed with the first series of 20 aligners began to reopen.

Following this development, the patient was reassessed and a second stage of treatment was planned.

This case became an instructive example of why the timing of a frenectomy can be important.

In orthodontic treatment, moving the teeth into the desired position is sometimes not enough. Anatomical factors that may influence those positions also need to be managed at the appropriate time.

Second Stage: Frenectomy and a New Series of 16 Aligners

After the frenectomy was completed, a second series of 16 clear aligners was planned to close the reopened midline gap and refine the final positions of the teeth.

As in the first stage, our patient remained compliant throughout the second series.

With this additional series, the tooth positions were refined and the gap between the front teeth was closed again.

The active clear aligner treatment was therefore completed in two stages:

First series: 20 aligners
Second series: 16 aligners
Total: 36 aligners

However, from our perspective, the treatment was not yet complete.

Especially in diastema cases, one of the most important stages of treatment is maintaining the result that has been achieved.

Why Was a Second Series of Clear Aligners Needed?

The need for a second series of clear aligners does not necessarily mean that the initial treatment was unsuccessful.

Orthodontic treatment is a dynamic process.

Biological tooth movement, bite relationships, patient compliance with aligner wear, and anatomical factors such as the frenulum can all influence the course of treatment.

In this case, the patient’s compliance with aligner wear was excellent, and the planned tooth movements had been achieved by the end of the first 20-aligner series.

However, following the delay in the frenectomy, the midline gap reopened.

For this reason, after the frenectomy was completed, treatment continued with a second series of 16 aligners.

The purpose of the second series was not simply to close the gap again, but also to refine the final positions of the teeth and complete the treatment in a controlled manner.

Why Is Retention Important After Diastema Treatment?

Once the gap between the front teeth has been closed, active orthodontic treatment may be complete, but the process of maintaining the teeth in their new positions continues.

This stage is known as the retention phase.

Particularly in cases where a midline diastema has been closed, the possibility of the teeth separating again needs to be considered.

For this reason, we completed our patient’s treatment using two different retention methods:

Fixed retainer + Essix retainer

A fixed retainer is bonded to the back surfaces of the front teeth to help maintain their new positions.

An Essix retainer is a removable appliance that provides additional support during the retention phase.

At Ozant Dental Clinic, in suitable diastema cases, using these two methods together forms an important part of our approach to maintaining the results achieved through treatment.

Keeping the gap closed is just as much a part of treatment as closing it.

Not Every Patient Who Says “My Teeth Have Gaps” Needs the Same Treatment

This case also demonstrates why an individualized assessment is essential in diastema treatment.

Two patients may have gaps of a similar size between their front teeth, but the underlying causes can be completely different.

For one patient, tooth size may be the main factor. For another, tooth position, jaw structure, missing teeth, or the attachment of the frenulum may play a role.

Therefore, the answer to the question “Can the gap between my teeth be closed with clear aligners?” will not be the same for every patient.

Several factors should first be evaluated together, including:

the cause of the gap,
the size and position of the teeth,
bite relationships,
the structure and attachment of the frenulum,
any additional procedures that may be required,
and the retention protocol to be used after treatment.

An individualized orthodontic treatment plan can then be created.

Can Gaps Between Teeth Be Closed with Clear Aligners?

In suitable cases, clear aligners can be used to close gaps between the front teeth.

However, the important point is not simply to create the tooth movements required to close the space.

Especially in diastema cases, it is necessary to determine why the gap developed and assess the risk of it reopening after treatment.

For this reason, when planning clear aligner treatment, the focus should not be only on “how many aligners will be needed”, but on the treatment process as a whole.

This patient was a good example.

We closed the gap with the first series of 20 aligners.

Following the delay in the frenectomy, we observed that the midline gap had reopened.

The frenectomy was then completed.

Afterward, we closed the gap again with a second series of 16 aligners.

Finally, we moved into the retention phase using both a fixed retainer and an Essix retainer.

Diastema and Clear Aligner Treatment in Nicosia

At Ozant Dental Clinic in Nicosia, Dr. Yusuf Ozant evaluates each patient undergoing clear aligner or orthodontic treatment according to their individual dental, jaw, and bite characteristics.

For patients with gaps between the front teeth, the goal is not simply to reduce the distance between the teeth.

Understanding the cause of the gap, planning the required tooth movements, assessing any anatomical factors that may influence treatment, and establishing an appropriate post-treatment retention protocol are all parts of the process.

This is why two patients who appear to have the same complaint—“My teeth have gaps”—may require very different treatment plans.

What This Case Taught Us

This patient’s treatment involved a total of 36 clear aligners.

However, describing the case only in terms of the number of aligners would leave out the most important part of the story.

The actual treatment journey involved:

closing the gap for the first time with 20 aligners,
the gap reopening following the delay in the frenectomy,
completion of the frenectomy,
closing the gap again with a second series of 16 aligners,
and maintaining the result with a fixed retainer and an Essix retainer.

In orthodontics, one of the most valuable aspects of treatment is not necessarily having the original plan remain completely unchanged from the first day to the last.

Monitoring the patient throughout treatment, correctly evaluating any changes that occur, and modifying the plan when necessary are also important parts of orthodontic care.

This case once again demonstrated an important principle:

Closing the gap between the front teeth may be the goal. But understanding why the gap developed and trying to prevent it from reopening are part of the treatment as a whole.
