Clinicians from all over the world participated to Osstell Scientific Symposium at EAO Congress 2018 in Vienna, on October 11th.
Have you ever placed an implant in an augmented bone site and added another few months of healing time just to be on the safe side?
It has long been recognized in the dental implant literature that implant stability is a critical factor in predictable treatment outcomes. Both primary stability (mechanical stability) and stability prior to provisionalization or restoration of the implant should be considered in the individual treatment plan. The secondary (aka biological stability) will indicate the level of osseointegration when compared to the initial primary stability (mechanical stability) at placement of the implant. There are other factors, of course, to be considered but there is little disagreement in the literature that implant stability is key.
Physiologic healing after implant placement varies from patient to patient and site to site. Surgeons must find balance between mechanical stability and avoiding excessive trauma to alveolar bone, especially the cortical bone found at the alveolar crest. The two measures of quantifying primary stability are insertion torque volume (ITV) and resonance frequency analysis (RFA). Implant stability quotient or ISQ is a value used to determine stability via RFA.
Primary and secondary stability is a much discussed topic. Which one should a clinician aim for to achieve successful implant treatments? We met with Dr. Stephen Jacobs after his lecture at the AO Annual Meeting about primary and secondary implant stability to clarify things.
Could you explain the difference between primary and secondary stability?
Measuring ISQ has become a critical component in my implant treatment, as it provides objective information about the stability of the implants I place. Based upon the initial implant stability or ISQ value, I determine the loading protocol and timing of restoration (immediate, early, delayed).
I have been placing dental implants since 1998 and as most of you, I have seen many advances in the field of dentistry that make implant dentistry safer and more predictable. The biggest boon to treatment absolutely has to be the advent of CBCT technology. This has made the surgical phase of treatment more predictable and safer for the patient.
Dr. Michael Norton talks about Osstell ISQ and RFA in his practice. Dr. Norton has been using Osstell for many years and has found value in having the information it provides to him about his patients. In addition, Dr. Norton is just completing his term of office as President of the Academy of Osseointegration which will hold its 2018 Annual Meeting in Los Angeles February 28th through March 3rd. We and Dr. Norton welcome your comments and questions on his thoughts.
Clinicians from all over the world participated to Osstell Scientific Symposium at EAO Congress in Madrid, on October 5th. This year’s symposium featured Dr Steven Eckert, Dr Giorgio Tabanella and Dr Luis Cuadrado.
We sat down with moderator Dr Marcus Dagnelid, from Gothenburg, Sweden, and collected his thoughts and reflections of the scientific content of the symposium on this blog post. Ask questions to Dr Marcus Dagnelid in the comments at the bottom of the page!

I was curious about the correlation between immediate insertion torque (IT) and ISQ and wanted to study it in my practice. This is a study I conducted and it was published in IJPRD recently. The study protocol and findings are posted here for you to read and comment on.
Every day we do a lot of things based on our intuition. We make decisions based on our own or others experience.
We do not need science to help us in our daily life, and we don't have a clear indicator that shows us if our decision is the best.
Decisions based on practical experience is our way of life.
But when it comes to our profession as dentists, we do, or at least we should, evidence-based dentistry for...almost every treatment we perform.
As the title of this article says, I´m going to present a case about "progressive loading."
Yes, I know, progressive loading is supported by few clinical studies (Rotter 1996, Appleton 2005, Ghoveizi 2013), but -and here comes the interesting part- the rationale behind this concept makes sense from a clinical and biological point of view.
