1st Scientific Conference for Aligner Orthodontics

With over 300 participants, a complete success

Stuttgart,6 December 2010

With 320 participants, 32 internationally recognised speakers and 18 industry partners, the 1st Scientific Conference for Aligner Orthodontics on 26 and 27 November 2010 in Cologne was a resounding success. The organiser, the German Association for Aligner Orthodontics e.V. (DGAO), is delighted at the extraordinary response to its first conference.

For two days, technical lectures on a wide variety of aspects of all existing aligner systems were given in the conference rooms of the prestigious InterContinental Hotel in Cologne. In a pleasant atmosphere, the interested expert audience was able to exchange ideas with the internationally renowned experts. The 1st Scientific Conference for Aligner Orthodontics was the largest, non-proprietary event to date, offering an appropriate forum exclusively targeted in its entirety towards aligner therapy.

The start of the convention was heralded in on Friday with a pre-conference on the topic of “Billing and Legal Matters”. Prof. Robert Fuhrmann fromHallealluded in his opening presentation, “Reimbursability, Approvability and Cost Effectiveness of Aligner Orthodontics”, among other, things to the difficulties in the wake of the new (German) Insurance Contract Act. The forensic topics were supplemented by Mr Dirk Franke and Mr Marek Abram from the perspective of an insurer (DAEV/AXA), while Miss Alexandra Petersen, from pvs-mefa Reiss, succinctly explained the professional handling by expense reimbursement bodies in her presentation. The pre-conference, which the large number of practising orthodontists found interesting, ended with the presentation by the solicitor, Michal Zach, who examined the legal aspects of aligner treatment in particular. Throughout the following, extensive scientific programme of the main conference, on Friday and Saturday, Prof. Emeritus Rainer-Reginald Miethke (Doha,Qatar), the President of the DGAO e.V., moderated in a practised manner. His insightful introductory presentation described the history of the development of the aligner, from the early beginnings in the post-war period, through the market launch of the invisalign system in theUSAandEuropeat the turn of the millennium, right up to today's indications for aligner treatment. Thanks to a variety of national and international contributions (Italy,Austria,Switzerland,USAandKorea) on the use of aligners in the practice and in the college, the programme was captivating. So, reports were given on the technique and the clinical application of the Clear Aligner System by Dr Tae Weon Kim (Korea) and in an invigorating, pragmatic manner by Dr Bruno Wilhelmy from his practice inDuisburg. The conference president, Dr Julia Haubrich, referred to impressive results in her presentation of Class II treatment using the invisalign System, while Dr Werner Schupp, also fromCologne, presented the indication for invisalign, in particular in the treatment of cranio-mandibular dysfunctions. Dr Boris Sonnenberg, fromStuttgart, addressed himself with his habitually perfect performance to the difficult topic of Class III treatment in combination with maxillofacial surgical intervention. One of the most experienced users, Dr Marko Tribò fromZurich(Switzerland), gave a lecture on the options and limitations of extraction treatment with the invisalign system. Dr Thomas Drechsler, fromWiesbaden, on the other hand, was able to demonstrate the advantages of treating children and adolescents using the new Align Technology invisalign teen product, specially adapted for the requirements of young patients, for his interested audience in his detailed and at the same time entertaining presentation. Dr Mitra Derakhshan (USA) gave an enthralling insight into the future innovations by Align Technology Inc., with a “sneak peek” at the G3-Evolution by invisalign, coming next year. If it is a matter of further development in the area of modern orthodontics, Prof. Hinz (Herne) always has the floor, as well. He demonstrated the impressively rapid results with theELASTO items and introduced the Lamitec® technique while pointing out the new options for metal-free retention using milled zirconium dioxide retainers (ortho-circ®). Dr Baerbl Reistenhofer fromVienna(Austria) gave an insight into the new target group among her patients, a clientele consisting of lifestyle and business celebrities and artists, who can now be successfully treated with the invisalign technology. FromItaly, Dr Andrea Bazzucchi singled out the importance of interdisciplinary collaboration, in order to be able to achieve aesthetically perfect treatment results with the aid of invisalign treatment. In addition, further aligner systems such as the German product, Alphalign®, were introduced in the joint presentation by Dr Uwe Peterseim and Dr Jutta Huesch in interesting perspective. Dr Roland Jonkmann explained the mechanism of action of the Essix A and Essix C apparatus by Dentsply Raintree Essix®, according to the biomechanical principles of Force + Space + Time, which were once postulated by one of the pioneers of aligner therapy, Dr Jack Sheridan.

The numerous scientific contributions by various colleges in Germany and Italy introduced the working group of Dr Jochen Langer and Dr Sebastian Zingler (Technical University of Darmstadt / University of Heidelberg), with a microscopic view through the 3-D electron scanning microscope in the depiction and examination of teeth for approximal enamel reduction. Dr Elena Krieger (UniversityofMainz) presented the audience with a research paper on metric investigations of the accuracy of aligner treatment with a look at further studies (Simeon Haag). What movements with an aligner should be efficiently realised were depicted, precisely scientifically evaluated by Dr Christoph Bourauel of theUniversityofBonn, even if, in conclusion, he had to declare laconically in his Rhenish dialect on the precise, actually effective forces: “ma weset net!” – “they dinae know!”. Dr Tim Schott (UniversityofTubingen), on the other hand, was able to explained very intelligibly the precise mechanism of action by means of which the blue invisalign-teen Compliance Indicator fades. Miss Isabelle Schaefer, in her well-founded investigation in concert with Dr Bert Braumann and Dr Joerg Schwarze, was simply able to demonstrate the negligible impacts of halitosis or of restricted quality of life scientifically. Dr Maria Paola Guarneri of theUniversityofFerrara(I) considered the possibilities of representing applications of force in the invisalign technique by means of fluorescent indicator pastes in her biomechanical address.

The multifaceted Conference, which examined the practice-relevant and scientific aspects of a wide variety of aligner systems on the market, was rounded off by the conferral of honorary membership of the DGAO upon Professor Guiseppe Siciliani of the Universityof Ferrara(I) for his particular services to teaching and research in aligner orthodontics. With the highly entertaining and vigorous contribution by Dr Stephan Hoefer on the fun and the effects the patients and the practice team can have with bleaching methods, together with the interesting concluding presentation of his summary of the prospects and limitations of aligner treatment up until the present by Dr Joerg Schwarze, the 1st Scientific Conference of the German Association for Aligner Orthodontics in Cologne ended successfully on Saturday evening.

In general, the good mood and the pleasant atmosphere at the InterContinental Hotel were lauded by the participants. “Thank you very much to all those responsible for a Super-Conference!!!! I guarantee I'll be back in 2012 and I am already looking forward to it”, wrote one participant after the Conference. There was also great praise from the industry partners in the dental exhibition which accompanied the Conference. “We did not expect such great interest!”, for example, according to the exhibitor, Komet, and pvs-mefa Reiss commented that they were “extremely pleased with the Conference”. Align Technology was also “positively astonished by the large number of participants”.

Owing to this positive response, the next scientific conference will again take place inColognein two years. This time, in the Guerzenich inCologne. The date: 23 and 24 November 2012.
