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
How I Combine Research and Treatment in the Europaviertel
At Skyline Orthodontics in Frankfurt’s Europaviertel, right next to Skyline Plaza and near the Frankfurt Trade Fair, I combine scientific research with daily clinical practice. You can find all the details about the treatment process, eligibility, and the options available with Invisalign on our aligner services page.
