How long does invisible braces treatment take?

Here is the answer to one of the most frequently asked questions. It is always advisable to see an orthodontist who specialises in invisible braces for this type of treatment.

In this post we look at the treatment time of the two most widely used invisible braces systems on the market: Spark and Invisalign.

Factors that can affect how long treatment takes

Different factors can influence how long your invisible braces treatment takes: from the complexity of the case to your dental care habits.

Every detail can affect the time needed to achieve satisfactory results sooner or later.

Alignment of the teeth: patients whose teeth are fairly well aligned before treatment, whether through genetics or because they have had braces before, will need less time.
Complexity of the case: treatment time depends a lot on how complicated your case is. If more movements are needed, such as correcting a crossbite, an open bite or very crowded teeth, it may take longer.
Daily and dental habits: habits such as biting your nails, constantly chewing gum or smoking can affect how well the treatment works. Untreated gum disease or poor oral hygiene can also slow down tooth movement and therefore lengthen treatment.
Not following the orthodontist’s recommendations: on average the aligners must be worn 22 hours a day, meaning they should only come out for meals and brushing.
Follow-up: it is vital to attend all your follow-up appointments. Missing appointments or not following the recommendations can lengthen treatment.

How long does Spark invisible braces treatment take?

Spark invisible braces are an innovative option that gives fast, effective results for correcting dental problems.

Treatment time with Spark varies with the complexity of each individual case, but in general it usually takes between 6 and 18 months.

This system uses custom clear aligners to move the teeth gradually into the desired position. Unlike traditional treatment with metal brackets, Spark is discreet, comfortable and practically invisible.

The exact treatment time depends on several factors, such as the severity of the malocclusion, the initial alignment of the teeth and how closely the patient follows the orthodontist’s instructions on wearing the aligners.

There are different types of Spark treatment depending on the patient’s case. The duration will be longer or shorter depending on the type of aligner you need.

SPARK 10: the quick option for minor adjustments

Indicated for relapses (teeth that have moved again after a previous treatment), pre-prosthetic treatment and minor malocclusions.

SPARK 10 offers a maximum of 10 aligners and one refinement. This option provides an efficient, personalised solution for improving alignment quickly and effectively.

In this case treatment time is shorter. The estimated duration of SPARK 10 treatment is generally 3 to 6 months.

This is significantly shorter than other invisible braces options thanks to the limited number of aligners used, which is ideal for specific, targeted adjustments.

SPARK 20: the intermediate option for moderate corrections

SPARK 20 treatment is designed for moderate malocclusions that need more detailed attention than simple relapses or pre-prosthetic needs, but are not complex enough to need an advanced treatment plan.

SPARK 20 allows up to 20 aligner stages for effective correction. It also offers the option of two refinement sequences, guaranteeing precise, lasting results.

The estimated duration for patients using SPARK 20 is usually between 12 and 18 months.

This variation depends on individual factors, such as the severity of the malocclusion being treated and the patient’s commitment to wearing the aligners properly.

It is essential to follow the recommendation of at least 22 hours a day of wear to ensure the treatment works.

SPARK Advanced: the complete solution for complex cases

This comprehensive treatment is specially designed to tackle complex dental cases effectively. With no restriction on the number of aligners used and the possibility of unlimited adjustments.

SPARK Advanced offers a complete, personalised solution for achieving a perfect smile.

Since SPARK Advanced handles the most challenging cases, treatment can take longer, generally between 18 and 24 months, or even more, depending on the specific complexity of each case.

It is important to remember that the exact duration can vary from one patient to another, depending on how each one responds to treatment and on their commitment to wearing the aligners properly and consistently.

To get the best results within the estimated time, it is crucial to follow the orthodontist’s recommendations, especially on the number of hours a day the aligners are worn.

How long does Invisalign treatment take?

Having looked at Spark, let us move on to Invisalign, which is quite similar. The duration of this invisible braces treatment is related to the type of aligner you use.

The duration varies from case to case, and here too there are different types of treatment. Let us look at each of them, since the duration depends on the type of clear aligner you need. 

Invisalign Express

This is the fastest type of treatment and the most suitable for mild cases or for people who have had braces before.

It uses 2 sets of 7 aligners , with a duration of 3 to 6 months. 

Invisalign Lite

This treatment is for patients who have a generally correct bite but need small adjustments to perfect their smile.

It is especially effective for correcting the position of specific teeth and tackling mild alignment problems.

This treatment offers a precise, personalised solution for improving the look and function of your smile without the drawbacks of traditional brackets.

It includes 3 sets of 14 aligners, with an average duration of 8 months to 1 year.

Invisalign Full

For more complex cases, such as pronounced open bites or crossbites, Invisalign Comprehensive is the most suitable option. This exhaustive invisible braces method allows complete, effective correction.

The typical duration of this treatment is around 18 months, although it can vary with each patient’s specific needs.

Unlike other treatments, Invisalign Comprehensive has no preset limit on the number of aligners used or on treatment time, which makes it the most versatile option in the invisible braces range.

The duration and the number of aligners needed depend on how long the teeth take to correct their position completely.

Given their complexity, both this treatment and Invisalign Teen can take up to 2 years in total. That extra time, however, translates into exceptional results and a completely transformed smile.

Invisalign Teen

Teenagers can also enjoy the benefits of invisible braces. It is a treatment similar to Invisalign Full, with the only difference that it is adapted for teenagers and children.

In short, how long invisible braces treatment takes depends on each case and on your situation as a patient. It can range from 3 months to 2 years depending on the complexity of each case.

Every mouth is different and these are always approximate times. If you need a more precise answer for your case, you can book your free first visit and we will be happy to see you.
