Invisible orthodontics is an innovative treatment method that has revolutionised the field of dentistry. It allows orthodontic treatment to be performed without the need to wear traditional appliances that are visible from the outside. Instead, invisible orthodontics uses transparent, custom-made appliances to correct the alignment of the teeth. This treatment method has become extremely popular because it offers a discreet and comfortable solution for people who want to improve the position of their teeth without having to wear discreet appliances.

The process of an orthodontic consultation

Completing the medical questionnaire form: when you arrive at our clinic, you will be asked to fill in a medical history questionnaire with your details, which will take about 10-15 minutes.

Consultation: After completing the anamnesis, Dr. Eszter Pál orthodontist will call you into the consultation room to discuss the problems and questions you have come to us with.

Examination, X-ray: Our specialist will examine you and if necessary, we will take an X-ray of you (X-ray is included in the package).

Digital planning: after reviewing the scan, our specialist will see if SPARK™ aligner braces are right for you. If you would like to see what results you can expect, you can have a digital design done on site. The cost of the design is 70€

Intraoral scanning, photography: if you would like to have a design, we will take an impression of your teeth using an intraoral scanner and take photos of the current condition.

Course of treatment: once the plan is ready, you will be contacted and you can discuss the course of treatment with the Doctor again in an online or face-to-face consultation. /The plan will take up to 1 week to complete.

Order, transfer: If you accept the treatment plan, we will order the splints. Your package will arrive in approximately 3 weeks. You will receive the splints in a personal consultation, you will be able to try them out and the Doctor will give you a detailed introduction to SPARK™.


Dr. Eszter PálOrthodontist

I am Dr Eszter Pál, orthodontist. I graduated from Semmelweis University in 2015. I have been attracted to the field of orthodontics since I was a child, and during my own orthodontic treatment I got to know the practice environment during my monthly adjustments.

During my university studies, I therefore paid special attention to orthodontics, winning an apprenticeship and assisting in a private practice. During my residency I was introduced to several types of orthodontic systems, from traditional braces to active and passive self-ligating appliances. I also worked in private practice in England until 2023, where I immersed myself in the use of invisible splint orthodontic systems.

After trying out several techniques, I finally found the orthodontic appliances that allow me to provide my patients with the highest quality of care. I use only Damon™ braces as they are gentle on the teeth and bone structure, and minimise discomfort, allowing me to achieve a quick and stable result. And for braces with aligners, I use the American Spark™ Aligner system, which is more comfortable, less visible and more effective than the average aligner thanks to continuous development.

    Invisible and removable: teeth can be aligned not only with a fixed appliance glued to the teeth, but also with removable rails. These are transparent, thin, plastic foil pressed rails, which are virtually invisible to the outside observer and can be removed and replaced at will with a single movement.

    Computer-aided design and printing: based on a sketch, the design is produced using the most modern 3D computer-aided design software known today. The process of tooth movement can be viewed in several views and videos. The arrangement of the teeth from their initial position to their planned position can be checked individually and on top of each other in projected photographs, as well as in spatially rotatable models. The rails are made from 3D-printed tooth samples with increments of a few tenths of a millimetre.




    Not perceptible to the observer from the outside.


    Invisible braces do not require getting used to and do not cause any discomfort. Moreover, there are no unwanted accidents, so there is no need for immediate medical intervention.

    Great value for money

    The aligners can be ordered individually or all at once.


    More aesthetic than any fixed appliance.


    You can calculate how long it will take until the next delivery of the new splints, how many splints will be needed and how much it will cost. Orthodontic treatment of a patient who lives far away or is busy can continue without interruption.


    It can be removed when needed (e.g. before eating, drinking, brushing teeth).


    Limitations: Adjusting a midline or occlusion is not possible alone, but only with additional or preparatory treatment.

    Requires cooperation: If you wear the splints less than recommended, the treatment will not progress. If you replace them more quickly, tooth movement may slow or stop.

    Regression: If you do not wear the splint for a few days or weeks, the teeth will return to their original position.

    1. IMPRESSION TAKING: The doctor takes a digital impression using an intraoral scanner. This is state-of-the-art technology that takes the impression from the dentition with 100% accuracy. The impression made with digital technology is sent by the doctor to the dental laboratory together with oral photos and panoramic X-rays.

    2. VISUAL PLAN: Based on the digital or digitized impression and the treatment plan, the orthodontist creates the virtual plan using the most advanced spatial computer program known today. This shows, in the form of an animation that can be downloaded from the Internet, step by step how the teeth move into the desired position. The motion sequence can be checked using videos from multiple views, superimposed images and models that can be rotated in space. The library, which is stored in the cloud, can be viewed online or downloaded.

    The plan can be changed after consultation with your doctor. If approved, the splints will be ready in about 1 week.

    3. MANUFACTURING TRANSPARENT RAILS: Once the virtual plan is completed after the doctor’s approval, the lab prints all the virtual samples on a 3D printer, resulting in the desired outcome, and then the rails are manufactured and the treatment can begin.

    TREATMENT TIME: The treatment time, i.e. the number of splints, can vary from a few months to several months depending on the degree of irregularity of the teeth.

    TIME TO WEAR THE ALIGNERS: Although they can be removed and reinserted at will, unless the doctor orders otherwise, the rails must be worn for 20-22 hours a day. They can be worn for shorter periods of time, but when they are removed, they are pulled back into their original position by the fiber network that holds the roots in place. The splints should be replaced every 2 weeks.

    THE FIT OF THE TRAYS: Each tray is actually a step toward the intended condition, so the trays may not fit perfectly on the teeth at first.

    INSERTION AND REMOVAL: Initially, removal of the splints can be made easier by using an auxiliary tool to grip the sides of the splints.

    BRUSHING AND CLEANING: The splints must be removed before meals. After meals, a brief brushing is recommended before reinsertion. Clean the splint at least once a day with a toothbrush and toothpaste. To disinfect the braces, we recommend using a cleaning tablet (e.g. Corega), an aqueous solution of citric acid or baking soda (1 knife tip dissolved in a glass of water).

    COOPERATION AND EFFICIENCY: Perfect cooperation of the patient is necessary for successful treatment. Getting used to the appliance system takes a few days. After a longer period of time, the current splint does not fit in the mouth anymore. The teeth may not be aligned as they were in the previous steps, so none of the previous splints will fit. In this case, a new splint may need to be made based on a new impression and plan.

    MEDICAL CONTROL: The splints should not be used without medical control. During treatment, check-ups are usually performed every two months and the current splints are applied. In case of problems with wearing (fractures, pressure, cannot be put on), contact your doctor. In case of inflamed gums, cut a strip of several millimeters from the painful edges of the foil. Excessive pressure may cause whitish, bloodless patches to form. Ischemia does not cause permanent damage to the gums or teeth.

    TREATMENT OF A RECLAIM: In some cases where treatment has been interrupted for any reason, it can be resumed by deviating from the existing patterns. However, in other cases, a new design and splints may be required.

    RISKS: Like all medical procedures, orthodontics involves risks and unpredictable consequences. During orthodontic treatment, there is an increased tendency for root resorption. Moving a tooth that has been previously traumatized or had a root canal can also pose a risk. In rare cases, an allergic reaction may occur. Inadequate oral care can lead to gum recession around the teeth and bone pockets. The temporomandibular joint does not always adjust to the new position, so temporary joint pain and clicking may occur. Teeth that are not covered by the splint may protrude compared to neighboring teeth.


    I just got the aligners and the first one does not fit my teeth perfectly

    The splints are not made from the current position of the teeth, but from a repositioned position so they can move the teeth and therefore do not fit like a retention splint.

    The edge of the aligner really break my gums. Can I cut them off where it hurts?

    Yes, you can cut off the edges of the splint where it hurts or presses too hard. It is recommended to use nail scissors so you don’t get a burr.

    Can I drink or eat with my aligners on?

    You have 2 hours a day to do whatever you want without the aligners. If you eat, drink, or brush your teeth, take the aligners out and then put them back in.

    I didn't wear my aligner for 22 hours one day. Can I switch to the next one?

    It is usually recommended to wear the splint 22 hours a day for 2 weeks. This ensures proper bone remodeling! If this is not observed on one day, this day does not have to be counted towards the two weeks!

    I put the first aéigner on and I can't take it off! Maybe I got the wrong quality aligners?

    The splints are made of a special, flexible plastic foil that is heated and pressed onto the set-up pattern under vacuum. The surface tension of the saliva on the tooth surface and the accessories glued to the teeth further increase the adhesive force. It is recommended to grasp the splints at the outer rear edges and remove the upper splint by a downward and forward movement and the lower splint by an upward and forward movement with alternating rocking to the right and left. If this is unsuccessful, use the peel-off aid or wait 1 hour and it will be easier to peel off.

    At what age is invisible braces recommended?

    From the age of 14, when the change of teeth has already taken place and the patient is sure that he will wear the braces.
