1900 participants at Osteology Shanghai 2017

The 3rd National Osteology Symposium in China, which took place on 20-21 September in Shanghai, exceeded all expectations. With almost 1900 participants it was the largest National Symposium in the Osteology Foundation’s history.


Osteology Shanghai 2017 was the biggest National Symposium in the Foundation’s history. Almost 1900 participants attended the outstanding presentations by national and international speakers. The programme was accompanied by a big poster exhibition, three sold-out workshops.

The setting also set new standards for future congresses. The stage was located in the centre of the hall, and the audience was sitting around it. This had the advantage that even the last rows were not too far away from the stage, and everybody could see well. Also the speakers enjoyed this rather unusual setting, which allowed them to address the audience at 360°.

Massimo Simion and Wang Xing, the Chairmen of the Symposium, had put together a really astonishing programme, covering all aspects of oral tissue regeneration, and presenting the latest insights from research, which are relevant for the practice – always in line with the Osteology Foundation’s high standards for evidence based presentations and following its motto: “Linking Science with Practice in Oral Regeneration”.

Among the presenters from abroad were besides the Chairman Massimo Simion, Daniel Buser, Massimo de Sanctis, and Stefan Fickl. They also held theoretical and practical workshops on the second day of the Symposium. Shu Rong, Su Yucheng, Gong Ping, Zuolin Wang, Chen Bo, Chen Zhuofan, Ma Wei, and Wu Yiqun, were the speakers from China. At the end of each of the four sessions, a question and answer session allowed further insights into the topics.

Massimo de Sanctis talked about surgical techniques to enhance soft tissue aesthetics. He focused on flap design for covering single and multiple recessions (split-full-split), and in which cases, depending on the amount of keratinized tissue, a soft tissue graft is needed in combination with a coronally advanced flap (CAF). He also mentioned that it is possible to use soft-tissue substitute if the patient does not want an autograft to be harvested.

Daniel Buser shared with the audience his experience on the topic of implant placement after extraction, and the concept of early implant placement in combination with contour augmentation using GBR. The surgeon is the major contributor for successful implant placement, he explained. For augmentation, he said, that autologous bone chips in combination with DBBM give the best results. The autologous bone is needed for the cells and growth factors, and the DBBM for long term stability due to the low resorption. Buser also recommended slight over-contouring, and covering it with a double layer of native collagen membranes. Implant survival rates of 95% over 10 years could be observed with this approach. 

Stefan Fickl focussed on the topic of extraction socket in the aesthetic zone, and explained that immediate implant placement can prevent ridge volume changes, but only when the implant is placed in a palatal position, and when the gap to the bone is filled with grafting material. If ridge preservation is performed to preserve the volume for late implant placement, he recommended to fill the socket with DBBM, and to cover it with a 3D collagen matrix seal, i.e. a soft-tissue substitute, which leads to less scaring than autogenous tissue (Fickl et al., in press). In defect sockets he recommended the use of DBBM in combination with a native collagen matrix, and primary closure of the socket with a connective tissue graft.

Massimo Simion focussed on the treatment of more demanding cases, and presented regeneration concepts for vertical ridge augmentation. In the aesthetic area it requires a CTG, 4 months healing, and then a 3D augmentation with a mixture of autologous bone and DBBM (70:30), he explained. The provisional restoration must not touch the mucosa, for successful healing. A second soft-tissue augmentation should be performed before the final restoration is placed. After that the tissue will mature year by year.

A big thank you to the local organisers, to all speakers, from China and abroad, and to all participants for making it such a great event. We are already looking forward to the next symposium in China in three years from now.
