Invisalign by Issembert Paris

Invisalign, what is it ?

Invisalign is a custom-made aligner that moves teeth with clear aligners that the patient wears at all times, except during meals. These aligners are changed every two weeks or every week throughout the treatment.

The aligners are made from the impressions of your teeth. Once your impressions are taken in our Paris office with our iTero scan, Dr. Issembert performs the digital simulation of your treatment.
Without the orthodontist’s control over the simulation, treatment is random and unpredictable. Thus, one must always keep in mind that aligner brands such as Invisalign,

Clear Correct or Orthocaps are only plastic supports to move teeth, which, without the strategy that your orthodontist puts in place for your treatment, do not work.

In general, 3 to 4 pairs of aligners are given to the patient at each appointment which takes place every 2 to 5 months. It is possible, for patients living abroad, to extend the appointments even further. The patient must wear each pair for 22 hours a day and for two weeks before moving on to the next one.

For certain types of dental movements, our Invisalign patients in Paris can wear their aligners for only one week. At each appointment, adjustments are made to the teeth and aligners so that the movements can take place. Everything is done to ensure that the treatment takes place in the best possible conditions for the patient.

Treatable cases in Invisalignby Issembert

All orthodontic cases can be treated with Invisalign by Issembert. Dr. Issembert’s expertise allows him to obtain the same results with Invisalign as with other types of treatment, even for complex cases sometimes requiring surgery.

For example, the following cases can be treated with Invisalign by Issembert:

Articulé Croisé


A crossbite is a misalignment of the upper and lower jaws. One or more teeth of the lower arch may be outside the upper arch.

Dents recouvrement


The upper teeth overlap the lower teeth too much, which causes wear on the tips of the lower incisors and prevents the placement of a retention wire on top. The cases presented here combine moderate to severe overlap with these overlaps.

Dents en avant


In the case of forward teeth, stripping or extractions are used to generate space to move back. The cases presented here are cases of bi-proalveolarity, i.e. the two arches go together in the front.



The gap is characterized by the absence of contact between the upper and lower teeth. We speak of a posterior gap when it is located in front, and anterior when it is in the back that the contact is absent.

Chevauchements dents


Due to a lack of space on the arch, teeth overlap. Stripping is often used to create space in addition to the orthodontic forces delivered by conventional or invisible appliances. In more severe cases, extractions may be considered.

Dents triangles noirs


Some patients, for different reasons (gingival recession, loss of papilla) present black triangles between certain teeth. An orthodontic treatment associated with stripping allows the contact points between the teeth to be raised and the incidence of black triangles to be reduced.

Dents sous occlusion


When the lower teeth are more forward than the upper teeth. It is possible to correct this type of case by combining surgery with Invisalign treatment.

Dents espacées


These are spaces between the teeth that are corrected with orthodontic treatment. Depending on the nature of the spaces to be closed, the treatment plan is different.

Dents bout à bout


End-to-end is a malocclusion which, as its name indicates, refers to a situation where teeth from both arches touch each other end-to-end when closing the teeth, which generates wear on the teeth.

Autres cas orthodontie


The cases we have described here are the most common, but many specific cases may present themselves for treatment. These include surgical cases (Cl2, Cl3, etc), or cases with extraction.

What are the steps of an Invisalign treatment ?

From the first appointment to the retention wire, several steps are essential to the success of an Invisalign by Issembert treatment. Here is a detailed description of how your treatment will proceed:

Traitement Invisalign by Issembert

The First Consultation appointment

The first step of an Invisalign treatment is to determine if this solution meets your expectations and to make a diagnosis. Dr. Issembert’s expertise will allow him to propose Invisalign by Issembert for all types of cases, but first of all, it is necessary to carry out a diagnosis and to see with you your expectations, and the different possibilities of treatment and their implications (for example, with or without surgery, etc).

Beyond the clinical considerations, it is at this moment that we discuss with you the requirements of the treatment (wearing the aligners 22 hours a day in particular), and that we carry out an estimate which will enable you to know in detail your assumption of responsibility. Orthodontics Invisalign Pontoise 95.

The meeting of Empreintes, Photos et Radios

Once you have decided to begin Invisalign treatment, we take x-rays, photographs and impressions of your teeth. Don’t worry, this appointment is made fast and pleasant by our in-office equipment. A state-of-the-art iTero scanner allows us to take your impressions without paste, and without any discomfort. X-rays are also taken directly in our office, thanks to our specialized radiography equipment

Dr. David Issembert establishes a treatment plan

Once the impressions have been taken, Dr. Issembert works on the treatment plan, commonly called “Clincheck”, named after the associated software. The treatment plan is based on the impression, photos, X-rays, the initial consultation diagnosis and discussions with the patient. The doctor works on each tooth, one by one, the position of each cleat, of the possible stripping, and of all the elements of the treatment in order to obtain the final treatment plan, cut into trays that will progressively carry out the movements.

The installation of Invisalign gutters

Between 3 and 5 weeks after the impression, we schedule a fitting appointment at the office. During this appointment, which lasts about an hour, we place the cleats on your teeth, give you the first sets of aligners and explain how the aligners work and the rules to follow to ensure that the treatment goes smoothly.

Treatment and finishes

As your treatment progresses, we schedule office appointments every two to five months, depending on treatment needs. In some cases, treatment can be accelerated at a certain time, but this depends on the case and the progress of the treatment.

After the last aligner has been worn for two weeks, the treatment may require some adjustments to achieve a perfect result. This is not uncommon. Dr. Issembert, in agreement with the patient, and at no extra cost, makes a finishing impression and works on a treatment plan for the finishing touches. These aligners, in continuity with the others, will allow the desired result to be achieved perfectly.

Double restraint, a guarantee of stable treatment

Dr. Issembert attaches great importance to the durability of the treatment, and does everything possible from the beginning to ensure that there is no orthodontic recurrence. This involves a series of movements to be performed or avoided during treatment, as well as the use of a double retainer: a retainer wire glued to the back of the teeth from canine to canine at the top and bottom, and a safety splint. The wire must remain in place for life, and for this reason the treatment plan must foresee its position from the start, so that the occlusion does not jeopardize its hold. In addition, if the wire breaks, the retention trays, which should be tried regularly in the evening, provide a safety net to wear until the wire is repositioned in the office. This double retention is an essential guarantee of the good results of the treatment in the long term.

Invisalign By Issember to

The Invisalign by Issembert treatment is particularly suitable for adults, making it possible to obtain the same result as with braces through a discreet treatment adapted to an active everyday life, both in the professional and in the social and personal context.


  • It is an invisible treatment, the aligners are not visible unlike external braces
  • Gutters can be removed temporarily if you are concerned about their visibility, but this fear will soon fade.
  • The cleats are invisible because Dr. Issembert always positions them behind the front teeth


  • Appointments at the office are relatively short and spaced out, with extended hours to facilitate organization.
  • It is possible to eat all types of food without restriction because the trays are removed during meals.
  • The trays are easy to use and do not generate untimely appointments such as a detached ring or a broken wire.

Invisalign by Issembert for children and adolescents

Dr. Issembert also treats many children and adolescents with Invisalign clear aligners. Children and teenagers who want a discreet treatment are delighted to have an Invisalign treatment and follow the instructions for wearing the aligners to the letter!

In children, Invisalign aligners can be combined with early treatment appliances: circuit breaker or Herbst for example. Depending on the case, part of the treatment can therefore start with a certain type of appliance and then evolve to Invisalign aligners.

For example, for a girl who requires expansion and has a crossbite, a circuit breaker combined with Invisalign “aligners” may be considered in the treatment.


What are the recommendations during an Invisalign treatment?

Do whatever you want with your aligners, as long as you have excellent dental hygiene and wear them at least 22 hours a day. Brush your teeth well at least 3 times a day, and during the two days following the installation, do not eat anything too colored so that it does not stain the attachments you have on the side.

If the tray is irritating at first, you can apply orthodontic wax to the edges of the tray or file the irritating area with a nail file.

Frequently asked questions about the Invisalign by Issembert treatment

How long does an Invisalign by Issembert treatment last?

The duration of the treatment in Invisalign by Issembert varies according to each case. Most treatments last between 12 and 18 months. We pay great attention to the realization of durable treatments, without recurrence. It is possible to perform faster treatments, but the results will not be the same and the stability of the result will be compromised.

Is the Invisalign by Issembert treatment covered by social security?

If the treatment starts before the age of 16, the social security covers part of the treatment and then the mutual insurance company takes over.

If treatment begins after the age of 16, there is no longer social security coverage, but there are mutual insurance companies that reimburse part of the treatment. You can contact us by phone, email or on Instagram for more information.

If the treatment is ortho-surgical and begins after the age of 16, the social security system will pay for one semester of treatment.

Is the Invisalign by Issembert treatment covered by the mutual insurance company?

It all depends on your contract. The coverage is not always clear. When you come for your first consultation at Dr. Issembert’s Orthodontic Office, we call your mutual insurance company to help you find out what you are covered for. If you do not have any reimbursement, we recommend the VESPER mutual insurance company, which covers orthodontics for adults very well.

How much does an Invisalign by Issembert treatment cost?

Everything depends on the treatment. Each case being specific with many parameters, the price will depend on the case. At the end of the first orthodontic consultation, we will be able to give you a precise estimate specific to your case.

No. All food and beverages are allowed because the gutters are removed. So there are no constraints like for the rings.
