    Primary and Secondary Stability: What is Important and What Don’t We Know

    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) resonance frequency (RFA). Implant stability quotient or ISQ is a value used to determine stability via RFA.

    Decision-making in the retreatment of failures in implant dentistry

    Modern age of dental specialties is facing difficulties in treating patients who have been mistreated. Although “Primum non nocere” (“First do not harm”) should be the first goal of every medical doctor, nowadays we are used to see more and more often patients who present with iatrogenic effects or complications following a medical or dental treatment.

    Iatrogenic conditions do not necessarily result from medical errors, such as mistakes made during surgery, but sometimes they can occur also as a consequence of correct treatments, such as a supportive therapy in periodontics or bone regeneration in implantology, which maybe were not performed with a sophisticated and modern approach: what could have been considered as a good result in the past, today it could be defined as a failure, especially in terms of aesthetics and long-term stability of peri-implant tissues.

    Why secondary stability is crucial for successful implant treatments.

    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?

    How to reveal the secret that only bone and implant knows

    During the twenty-two years of my clinical and scientific work with dental implants I have been a witness to huge development in the implant dentistry. Changes to implants' macro and micro design, surfaces, and surgical and prosthetic procedures that expand today's treatment with dental implants. But for me, the most impressive improvement was an implementation of resonance frequency analysis (RFA) from scientific to clinical work in implant dentistry.

    How I determine loading protocol and timing of restoration

    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).

    How to Confidently Reduce Treatment Time? [With Case Report]

    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.

    Improve your implant planning for more predictable results

    In my daily practice as a prosthodontist I treat young adults between 18-25 years, with implants. There is not much available in the literature about implants for young adults and the little that exists is mostly about infra position of the implant crown or case reports. Instead, I want to share some thoughts and highlights around the actual treatment procedure. Aside from little available literature, there are not really any other sites or forums either - which I know of at least – with information and discussions about this specific topic. There are only a few Q&A’s about it online, and the answers are quite old.

    So what I am sharing here is based upon my own thoughts and my own experience, and it does not mean that I “invented” it in the first place. I however really try hard to create a this type of clinical environment on a daily basis, and I am passionate about raising it. Please do not hesitate to get in touch with me or share your comments below!

    Missing teeth in young dentitions are generally caused by congenital absence of tooth germs (aplasia) or by trauma and are mostly located to the anterior maxilla. Most of the patients, missing one or maybe two teeth, are treated with single implants but there are also patients with larger traumas or multiple aplasias that needs implant bridges. The implant sites in patients suffering from aplasia or trauma often have very restricted bone volume and many of these young patients have high smile lines showing the whole implant crown including the papillas and soft tissues (fig 1). In contrast to implant treatment in adults the challenge with young patients is also that the treatment is expected to last for a very long time, in most cases at least 60 years. During these years continued growth and changes in the face occurs which causes the positioning of the implant crown to change over time1-4. Due to all of the above mentioned, these cases need to be planned and performed as optimal as possible both when it comes to implant placement, implant stability, emergence profile and shape and shade of the crown5.

    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!

    The Correlation Between Immediate Implant Insertion Torque and Implant Stability Quotient

    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.

    How Progressive Loading Solved a critical Implant Case.

    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.
