Lectures & schedule 2022

Dear colleagues!

We will have our 24th International Symposium in Prague, again at the first of advent, Nov. 25 - 26, 2022. This time I am looking so much forward to see you all again in person, after our Symposium of last year had to be cancelled due to the pandemic situation. Hopefully, you have come through this extraordinary pandemic situation well.

The topic this time will be “Digital Workflow – effective or fancy?” We are all experiencing the digital revolution in our daily lives at a dramatic pace. If we want to introduce these digital conditions into our orthodontic practices, it will involve high investments. This means a material expense, but also a lot of things we have to learn anew. Therefore, we ask ourselves whether it is really effective, or rather fancy. After all, we want to make our diagnostics better and our treatment more successful. For this purpose, we have again invited top-class speakers. And of course, we are looking forward to the familiar togetherness that is so typical and so characteristic of our IOS-congresses in Prague. Have a safe journey, I am looking forward to seeing you in Prague!

Digital Workflow
– effective or fancy?

Prof. Dr. Dr. Ralf J. Radlanski (Berlin/Germany)

Digital workflow could be misunderstood as "fully automated". In my contribution, I would like to point out the tension between digital technology on one hand with its superior speed and its gigantic memory, to support us in automation, administration, record keeping, image analysis, treatment simulation, additive manufacturing of appliances, and on the other hand our medical experience, which is required to meet the individuality of the patient as much as personality and structural-biological peculiarities are concerned.

Take home message:
“digital workflow” does not mean “fully automated”.

11:30 / Friday, November 25th
Simon GrafCH

3D metal printing in orthodontics – no limits?

Simon Graf (Belp/Switzerland)

As 3d metal printing in orthodontics is becoming more and more popular, it’s about time to talk about the variations, possibilities and limits. Not just regarding of virtual design, but also on the metal printing process itself. Simon Graf will share with you his experiences, failures and pitfalls from 7 years of metal printing in orthodontics.

12:15 / Friday, November 25th
Dr. Dr. Wolfgang KaterDE

Functional and Aesthetic Aspects of Early Treatment Planning

Dr. Dr. Wolfgang Kater (Bad Homburg/Germany)

For a functionally and esthetically optimal result, the treatment of dysgnathia patients requires joint planning by orthodontists and maxillofacial surgeons from the very beginning. Our many years of clinical experience should help avoid misunderstandings.

13:00 / Friday, November 25th


14:00 / Friday, November 25th
Prof. Dr. Benedict WilmesDE

Overcoming aligner limitations by using palatal mini-implants

Prof. Dr. Benedict Wilmes (Düsseldorf/Germany)

An increasing number of patients seek orthodontic treatment with aligner therapy. Bodily tooth movement with aligner therapy is challenging when relying on aligners alone. Whilst there are limited reports of successful bodily molar movements of up to 2.5 mm in the literature, a very long treatment time and high level of patient compliance and is expected. Moreover, the potential side effects of intermaxillary elastics must be considered in terms of shift of the anchorage teeth; this might be a severe problem especially in unilateral elastics applications with the potential for development of a midline shift, arch rotation and a jaw discrepancy, and transverse occlusal canting. To avoid this anchorage loss and the high demand on elastic wear, orthodontic mini-implants may be used. Currently, the alveolar process is still the most preferred insertion site for mini-implants. However, due to a failure rate and the risk of root damage, insertion in the alveolar ridge is far from satisfactory. Other regions such as the anterior palate provide much better conditions for the insertion and stability of skeletal anchorage devices, as the amount and quality of the available bone is far superior. Mini-implants in the anterior palate with different types of abutments and connectors allow the construction of a large variety of anchorage reinforcing appliances. Utilising mini-implants in the anterior palate eliminates the risk of root injury and removes them from the path of tooth movement. In this lecture, the combination of mini-implant-borne appliances and aligners is presented to achieve more predictable results in aligner therapy.

Take home message:
TAD borne appliances do help to overcome aligner limitations

15:30 / Friday, November 25th

16:00 / Friday, November 25th
Prof. Dr. Aladin SabbaghDE

Hybrid orthodontics

Prof. Dr. Aladin Sabbagh (Erlangen/Germany)

Both clear aligners and braces were effective in treating malocclusion. We will share the experience how combining them can increase their biomechanical and aesthetical advantages, and decrease treatment limitations regarding transverse width, bite jumping, tooth movement, treatment duration, oral hygiene, comfort and stability.

17:00 / Friday, November 25th


Prof. Dr. Dr. Ralf J. Radlanski / Dr. Jan V. Raiman (15 minutes)

Digital Orthodontics appliances in daily practice

Dr. Veronika Ganchuk (Kiev/Ukraine)

Digitalisation of Orthodontic practice is a big step to improve diagnostic and treatment process. I will show you how I use digital splints, deprogrammers, RME, digital bonding and so on in my daily practice.

10:00 / Saturday, November 26th
Dr. Josef ŠebekCZ

Novel Methods in Combined Orthodontic and Surgical Treatment

Dr. Josef Šebek (Prague/Czech Republic)

The combined orthodontic and surgical management is the only possibility for solving problems of patients with severe jaw anomalies. New technologies such as 3D virtual planning of surgery and orthodontic treatment are changing our approach significantly. Even decades proven surgical are changing toward less invasivity and more effectivity.

11:00 / Saturday, November 26th
Dr. Esfandiar ModjahedpourDE

Digitalisation: is orthodontics easy now?

Dr. Esfandiar Modjahedpour (Krefeld/Germany)

Professional, state-of-the-art diagnostics have always formed the basis of every orthodontic treatment. This has not changed with today's new developments with digital tools. In fact, orthodontists need more training to use the digital tools for diagnosis, treatment plans and appliance design. What are the keys to an aesthetic and stable result and is there a science behind it?


Virtual treatment planning and appliance design: better quality of treatment for patient and orthodontist

3D treatment simulation and virtual appliance design have been around for a few years now. While some have embraced the new possibilities of CAD/CAM technology in orthodontics, others are hesitant. In this presentation three users of that technology who are in different phases of implementation will talk about how using digital orthodontics has changed their everyday work process for the better:

11:45 / Saturday, November 26th
Dr. Finn Geogheganir

Introducing digital design and manufacturing into an orthodontic practice – lessons learned

Dr. Finn Geoghegan (Dublin/Ireland)

Dr. Finn Geoghegan took over an established orthodontic practice in Dublin when he moved back to Ireland in 2016 after holding several positions in Australia, Hong Kong, and the United Kingdom. He wanted to optimize and streamline the established processes in his practice by implementing 3D treatment planning, appliance design and manufacturing in-house. His goal was to become independent from external suppliers for indirect bracket positioning and aligner treatment. Within two years he has established a “digital team” of three people who provide planning and manufacturing services within his practice. In his presentation he will lay out his digital journey, sharing his motivation, challenges, frustrations, and successes. He will talk about all aspects of the process: hiring and educating people, deciding for the right equipment, managing workflows and deadlines and how it impacted his patient’s treatment experience.

Take home message:
Establishing a digital workflow is not about buying stuff. It is about efficiently training people and introducing a structured workflow.

The cutting edge of 3D treatment simulation and appliance design – where are we, what’s the future?

Dipl.-Ing. Mag. Christian Url (Vienna/Austria)

DDr. Silvia M. Silli (Vienna/Austria)

Christian Url runs an orthodontic laboratory and software training centre in Vienna, Austria. His lab offers aligner therapy, robot based lingual and buccal indirect bracket positioning, functional appliances, and retainers – all based on digital treatment planning and appliance design and using computer aided manufacturing techniques. He also teaches the software suit his lab is using for all these products and services to interested orthodontic specialists and supports them throughout the implementation phase in their own practice. In his presentation he will show practical examples of how digital planning enables constant innovation in a highly economically challenging environment and how it allows to quickly create customized solutions to complex treatment problems. He will also give an insight into how 3D simulation facilitates communication between laboratory, orthodontic practice, and patient – an often overlooked, but important aspect in everyday workflow management.

Take home message:
Virtual treatment and appliance planning is the only way to provide individual solutions to complex treatment problems while being able to stay ahead in an economically challenging environment.

Dr. Björn LudwigDE

Virtual treatment planning and appliance design in everyday clinical practice

Dr. Björn Ludwig (Traben-Trarbach/Germany)

Dr. Björn Ludwig is in private practice in Traben-Trarbach, Germany. Throughout his professional career he has been at the forefront of innovation constantly evaluating, testing, and developing new technology in his own practice. Over the years he has established a robust digitally supported process between his laboratory and clinic with virtual design and 3D-printing / laser melting / milling at the core of his workflow. He will show how these technologies impact his everyday work and how they give him more control over his treatments, from diagnostics to finishing. He will also talk about how digital technology enables him to quickly and confidently react to unexpected developments in his treatments and present solutions only possible with virtual planning.

Take home message:
Digital tools allow you to be better prepared and make informed decisions before treatment begins and enable you to react quickly and solve unexpected developments during treatment.
