The 3rd International ISQ Symposium took place on October 13 in Athens, Greece, in conjunction with the EAO congress. It attracted more than 250 participants listening to prominent lecturers speaking about the clinical use of ISQ and related new research. The themes for this year’s EAO congress in Athens were Avoiding and Managing Complications, Risk Indicators, Loading and Treatment Protocols, and Outcome Predictability – all subjects correlated to the clinical benefits of using Osstell ISQ. Dr Marco Degidi, Italy, chaired the meeting and presented the three speakers:

Dr Jan Gottlow, Sweden
Researcher at the Department of Biomaterials, Institute for Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, private practice in Gothenburg.

Prof Peter Moy, USA
Professor, Department of Oral and Maxillofacial Surgery. Nobel Biocare Endowed Chair, Surgical Implant Dentistry. Director, Straumann Surgical Dental Center. UCLA, School of Dentistry.

Dr Paolo Trisi, Italy
Adjunct Professor, University of Chieti. Adjunct Professor, University of Naples. Private Practice in Pescara.

Dr Gottlow provided a thorough background presentation of Osstell ISQ and RFA technology, including clinical data and suggestions as to which values to expect in different situations. He presented data from other clinicians that were similar to the data presented by Prof Moy. Dr Gottlow also presented new data recently submitted for publication that correlated the ISQ measurement scale to lateral micro motion in implants.

The correlation between ISQ and micro motion was first presented in a publication in 2010 by the next speaker, Dr Trisi. Dr Trisi stated that although it would be preferable to make direct micro motion measurements in vivo, this is not possible. However, since the correlation to ISQ is very apparent, ISQ values can be used to indirectly assess micro motion. Micro motion of a dental implant is of course directly linked to the stability of the implant. He also presented data showing that although several different implants may be placed using the same final torque in the same bone quality, the micro motion of these implants can differ substantially, from 30-100 microns – indicating a similar difference in stability.

The final speaker, Prof Moy, presented clinical guidelines derived from more than 1,000 patient treatments – all assessed using ISQ measurements. The guidelines described different indications and how to use Osstell ISQ in various clinical situations. Prof Moy has more than a decade’s experience of using Osstell and showed that there seems to be a cut-off value at ISQ 56 for one-stage implants, below which the failure rate increases dramatically, to more than 10%.

“From these leading pioneers we learnt about the development of more specific clinical guidelines on how to use the ISQ scale. But also how well some very concrete meanings of implant stability – like micro motion – clearly correlates to ISQ. This demonstrates the importance of using Osstell ISQ - the only diagnostic instrument available that provides objective information about the progression of osseointegration - thereby helping clinicians make optimal loading decisions. This is especially important when treating higher risk patients”, said Jonas Ehinger, President and Managing Director, Osstell AB.
