It became obvious that there is huge interest in education on oral regeneration therapies in Russia. Not only was the auditorium in the modern Skolkovo congress centre always packed, the participants also stayed until late in order not to miss anything of the interesting discussions taking place.
The interest was overwhelming also on the second day of the symposium, when nine different hands-on workshops took place. They were all fully booked, and in some rooms additional seats were added for passive listeners, who could thereby hear at least the theory part, but were not able to practically apply what was taught. And again everybody stayed until late.
The chairmen of the symposium had put together a programme that was of huge relevance for the practice, with five international speakers, and also four local speakers, who covered all aspects of oral tissue regeneration therapies. The five international speakers were Sofia Aroca, Daniel Buser, Vivianne Chappuis, Frank Schwarz and Istvan Urban.
Sofia Aroca, France, reported in her talk that Class I and II multiple adjacent gingival recessions can be fixed. Complete root coverage can be predictably obtained by combining a deep knowledge of the healing property of the tissue to be treated and various surgical techniques (i.e. different flap designs), she explained. Connective tissue graft and soft tissue substitutes can be used to support the flap, or can be used every time the keratinized tissue is not present.
Natalia Romanenko, one of the national speakers from Russia, spoke about the role of keratinized tissue (KT), which is crucial for maintaining healthy teeth. Where KT is lost there is a higher probability that cementum will be exposed leading to bacteria accumulation and inflammation, she said. When a prosthesis is present, loss of KT could be even more dramatic, and lead to a reduction or loss of hard tissue. She presented several strategies to restore KT, such as personalized regeneration of the gum (patient own cells are expanded in vitro and transplanted back), laser-induced cell proliferation, or the use of soft tissue substitutes. Great results have been achieved using porcine collagen matrices, which she could demonstrate with a series of cases.
Vivanne Chappuis, Switzerland, spoke about the clinical relevance of dimensional ridge alterations in the esthetic zone for daily practice. Flapless extraction leads to less bone loss, but both, GBR and immediate implant placement, cannot preserve the facial bone completely. You have to respect the biology, she said, and know about the loss of the bundle bone. Depending on the risk profile and medical history of the patient, biotype, presence or absence of defects, and also financial reasons, the treatment should be selected (Chappuis et al. Periodontology 2017).
Osteology Expert Council Member Kristina Badalyan from Moscow gave a presentation about THE BOX, showing the participants the possibilities, tools and content, which the online platform offers for both, practitioners and researchers, working in the field of oral tissue regeneration.
The scientific programme was translated simultaneously from Russian to English, and vice versa. This allowed also discussions between the international and national experts and participants.
The symposium was accompanied by an industrial exhibition with main sponsors and other exhibitors, which was also very well visited. Industrial sponsors organised the majority of the workshops, too, and provided speakers for the industry forum on the morning of the second day, where many excellent presentations were held as well by renowned national and international experts.
A big thank you to the local organisers, in particular Anna Svir, who took over the local organisation together with Mikhail Baulin from SIMKO, as well as the coordination with the Osteology Office in Switzerland.
We are already looking forward to the next National Osteology Symposium in Russia in three years!
