Skyline Orthodontics Honored Once Again for Invisalign Research

Kieferorthopädische Behandlungen mit Alignern sind für mich mehr als Praxisalltag – ganz besonders mit Invisalign-Schienen. Sie sind auch einer meiner Forschungsschwerpunkte. Mein Name ist Privatdozent (PD) Dr. Babak Sayahpour, ich bin Kieferorthopäde in Frankfurt am Main und behandle bei Skyline Kieferorthopädie im Europaviertel. Umso mehr freue ich mich, dass ich 2026 zum zweiten Mal, nach 2023, mit dem Align Technology Research Award ausgezeichnet wurde: einem der international renommiertesten Preise im Bereich der Aligner-Forschung.

In this post, I’ll take you behind the scenes of this award: I’ll explain what the award actually means, what I’m currently researching, and why this is relevant not only to me as a scientist but also to you as a patient. Because ultimately, it’s clear that the results of our research are directly incorporated into the treatment we provide at Skyline Orthodontics using invisible aligners.


$25,000 in prize money for outstanding research on aligners

The Align Technology Research Award is presented annually to the best scientific projects in the field of aligner research worldwide—along with a research grant of $25,000 each, which goes directly toward the recipients’ ongoing scientific work. This means that in 2026, I will be among the select group of internationally recognized aligner researchers for the second time.

This continuity is no coincidence: I have been conducting in-depth research on aligner materials and the biomechanics of tooth movement for years, and I have supervised several doctoral students on these topics.

“It’s important to me that scientific findings are incorporated into our treatment and that we always stay up to date with the latest research.”

— PD Dr. Babak Sayahpour, aligner expert at Skyline Orthodontics


From the Habilitation to Everyday Clinical Practice

The habilitation is the highest academic qualification following a doctorate (the award of a doctoral degree) and is regarded as proof of exceptional scholarly expertise as well as the ability to conduct independent research and teach at the university level. As part of my habilitation, I have published numerous scholarly articles and also authored a habilitation thesis on the properties of aligner materials.

I completed my habilitation at Goethe University in Frankfurt am Main, where, upon its successful completion, I was granted the right to teach (venia legendi) in the field of dentistry, oral and maxillofacial medicine. Only a handful of researchers in Germany have completed their habilitation in the field of aligner material properties. This in-depth scientific expertise is directly incorporated into our daily practice and enables evidence-based treatment that reflects the latest scientific advancements. In addition, I regularly share my knowledge as a speaker at national and international professional conferences and continuing education events.

My current project, funded in 2026, examines aspects of biomechanics related to aligner treatment—an area that is becoming increasingly important for the precision and predictability of tooth movement. This commitment is complemented by additional specialized training, which is not always standard in orthodontics.

On the recommendation of my doctoral advisor at the time, Prof. Wehrbein, I pursued additional training in periodontology—the study of the periodontium—including at the renowned University of California, Los Angeles (UCLA). There, I was trained by, among others, Prof. Henry H. Takei, Distinguished Clinical Professor at the UCLA School of Dentistry and an internationally recognized expert in periodontology.

For many years, Prof. Takei ran a renowned private practice in the exclusive Bel Air neighborhood of Los Angeles—an area known worldwide for its many Hollywood stars and public figures. In addition, I was trained by Prof. Perry R. Klokkevold, then director of the UCLA Program in Periodontology. I also regularly completed clinical rotations at the periodontology practice of Dr. Todd Yamada in Los Angeles, who also serves as a faculty member at UCLA.

My commitment has always been—and remains—to excellence in orthodontics. Anyone who wants to do more than just move teeth—but rather provide long-term, healthy, safe, and stable treatment—must also understand the biological processes of the periodontium in great detail. It is precisely this in-depth knowledge of the gums, bone, and the biological principles of tooth movement that continues to inform every treatment plan at Skyline Orthodontics Frankfurt to this day.

This allows our patients to benefit from scientifically sound, exceptionally gentle, and precise treatment with aligners and braces—at the cutting edge of modern orthodontics in Frankfurt am Main. Before completing my specialty training in orthodontics, I also worked as a general dentist for about five years and received additional training in implantology from the International Team for Implantology (ITI) in London, among other places—a background that continues to help me understand the broader context of dentistry as a whole.


Why Skyline relies on multiple aligner systems, not just Invisalign

In addition to Invisalign, the best-known product from Align Technology, other providers such as Angel Aligner, Spark Aligner from Ormco, and the Korean company Graphy have established themselves on the market. When we manufacture some of the aligners ourselves in our own 3D printing lab, we use OnyxCeph software for planning.

Für mich zählt dabei nicht der Aligner selbst, sondern die sorgfältige Planung dahinter – gemeinsam mit meinen Patientinnen und Patienten definiere ich zunächst das individuelle Behandlungsziel. Ein erfahrener Kieferorthopäde in Frankfurt wählt das System danach aus, was dieses Ziel verlangt – nicht danach, welche Marke am bekanntesten ist.

“I don’t limit myself to a single aligner system; instead, I work with various aligner materials. It’s not the aligners that do the work—it’s the orthodontist who has a fundamental understanding of biomechanics and implements the treatment plan with precision.”

— PD Dr. Babak Sayahpour, aligner expert at Skyline Orthodontics


Five Criteria for Choosing a Good Dental Practice in Frankfurt

Nicht jeder Kieferorthopäde in Frankfurt, der Aligner anbietet, arbeitet mit demselben Anspruch – das gilt für Patientinnen und Patienten aus dem Europaviertel genauso wie für alle, die aus Bornheim, dem Ostend oder Seckbach zu uns finden.

Precisely because materials and systems are evolving so rapidly, it’s worth taking a closer look: How is treatment planned, how carefully is the material selected, and what actually happens after treatment is completed? These points can help you navigate the process:

  • Diagnostics – a comprehensive functional assessment that includes not only digital 3D scanning but also jaw movement and musculature
  • Digital Planning – Simulation Makes It Possible to Visualize the Desired Treatment Outcome Even Before Treatment Begins
  • Scientific Background – The latest research findings are continuously incorporated into treatment, not just once during training
  • Variety of Materials – Choose from a range of aligner systems instead of limiting yourself to a single brand
  • Retention and Follow-Up Care – A Clear Approach to Maintaining the Achieved Results Long-Term

Frequently Asked Questions About Invisalign in Frankfurt

Answers to frequently asked questions
What is the Align Technology Research Award?
The Align Technology Research Award is presented annually to recognize outstanding scientific projects in the field of aligner research worldwide. The award comes with a research grant of $25,000, which is allocated directly to the recipients’ ongoing scientific work. Applications are evaluated by an independent academic committee before Align Technology selects the final winners. In 2026, PD Dr. Babak Sayahpour of Skyline Orthodontics received the award for the second time, having first been honored in 2023.
What does this award mean for treatment at Skyline Orthodontics?
Wer nach dem Stichwort Kieferorthopäde Frankfurt sucht, kann die wissenschaftliche Tiefe einer Praxis von außen kaum einschätzen. Die Auszeichnung zeigt, dass die Behandlung mit der unsichtbaren Zahnschiene in der Praxis im Europaviertel nicht nur auf praktischer Erfahrung basiert, sondern auch auf aktueller, wissenschaftlich anerkannter Forschung zu Aligner-Materialien und Biomechanik. Für Patientinnen und Patienten bedeutet das: In die Planung der Behandlung fließt nicht nur Erfahrung aus dem Behandlungsalltag ein, sondern auch fundiertes Wissen aus eigener Forschung.
Does Skyline Orthodontics use only Invisalign?
No. In addition to Invisalign, the best-known product from Align Technology, other aligner systems—such as Angel Aligner, Spark Aligner from Ormco, or those from the Korean company Graphy—are also used, depending on the individual treatment goals. In some cases, aligners are even manufactured in-house at our own 3D printing lab. The brand is never the deciding factor; rather, it is the careful, individualized planning tailored to the specific treatment goal.
How much does aligner treatment cost in Frankfurt?
The cost of aligner treatment depends heavily on the individual’s initial condition, the extent of the necessary tooth movements, and the duration of treatment. Therefore, there is no flat rate that applies to every case. During a personal consultation at Skyline Orthodontics, we’ll discuss transparently and on an individual basis which treatment options are available and what costs you can realistically expect.
Are there any drawbacks to aligner treatment?
Above all, aligners require discipline: Only those who wear the aligners consistently will achieve the desired treatment result within the planned timeframe. Furthermore, aligner therapy is not equally suitable for every type of misalignment—in very complex cases, fixed braces may sometimes be the better choice. During a detailed initial consultation, we will therefore honestly and individually assess whether aligner treatment is truly the right option for your specific situation.
What experiences have patients had with Invisalign at Skyline Orthodontics?
Many patients particularly appreciate how discreet the aligners are in everyday life, as well as the ability to easily remove them for eating, drinking, and brushing their teeth. Many notice the first visible changes in their tooth alignment after just a few weeks of treatment. Another aspect that is frequently cited as particularly positive is that digital planning using 3D scans allows patients to see what the final result will look like even before treatment begins.
Is a retainer necessary after aligner treatment?
Yes, once active treatment is complete, a retainer is necessary to permanently maintain the results achieved. Without this follow-up care, there is a risk that the teeth will shift back slightly over time. Depending on the individual situation, either fixed or removable retainers are used. We will discuss which option is best for you toward the end of your treatment at Skyline Orthodontics in Frankfurt’s Europaviertel.
How long does Invisalign treatment take?
The duration of Invisalign treatment depends heavily on the severity of the misalignment and therefore cannot be predicted with certainty. Minor corrections can sometimes be completed within a few months, while more extensive tooth movements take significantly longer. Digital planning using 3D scans and simulations allows for a realistic estimate of the expected treatment duration right from the start, which is regularly reviewed throughout the course of treatment.
Is treatment with aligners painful?
Aligner treatment is generally considered gentler than traditional fixed braces, since there are no wires or brackets rubbing against the surface of the teeth. At the start of each new aligner, you may experience a slight sensation of pressure for a short time as your teeth are gently moved. This sensation usually subsides after a few days, so it has little impact on your daily life.
Kieferorthopäde Frankfurt: Für wen eignet sich eine Aligner-Behandlung?
Aligner treatment using invisible aligners is particularly suitable for adults with mild to moderate misalignments, such as crowded teeth, gaps between teeth, or rotated front teeth, as well as for minor bite issues. Working professionals, in particular, appreciate the ability to discreetly incorporate orthodontic treatment into their daily lives without visible braces. In cases of very complex misalignments, we’ll determine during an individual consultation whether aligners are the right solution or if another form of treatment would be more appropriate.
