Contaminated sterile packaged implants?
Our quality assessment of hundreds of dental implant samples revealed considerable residues on nearly every second tested dental implant. *
- No safety - despite FDA or CE approval of the medical device.
- Hidden danger - for patients and practitioners.
- Clinical risks - inflammatory processes, peri-implantitis, boneloss, implant failure
- Legal problems - more and more lawsuits for dental malpractice.
*) "Alarming results were found in the SEM/EDS-analyses on far too many dental implants from all over the world, even some of them were even made in Germany. All tested implants were sterile packaged and ready to use for patients. We are committed to fighting this most concerning situation! It is the ethical duty of us all, for the sake of our patients, for the safety of implant dentistry in general." Dr. Dirk Duddeck, Managing Director and Head of Research, CleanImplant Foundation

CleanImplant Pilot Study published
One surface characteristic of sterile packaged oral implants is their cleanliness. Oral implants may display different surface impurities of an inorganic or organic nature. These impurities may derive from the manufacturing handling and packaging processes and may remain on the commercially available implant. We are present ly lacking in knowledge of the precise clinical risks of implant impurities. However, contaminations are technically avoidable and, generally speaking, the authors assume all of us would prefer clean implants to avoid potential problems from surface impurities.
The article describes the problem on the implant market and the need for a global quality assessment. Criteria for "clean" implants, as well as the conditions for the globally established "Trusted Quality Mark" are discussed in detail in this paper.

2.1 million reports of bad dental implants
June, 2019: The Food and Drug Administration - FDA - has just released two decades of previously hidden data containing millions of malfunctions by medical devices.
This isn't the time to say "we told you so...". However, we should all be concerned, reconsider and double-check our choice of dental implant systems in the future. The question is: Can I blindly trust the information provided by the manufacturer or supplier?
Is the implant system that I use in my dental practice safe and at least free of major impurities? CleanImplant provides precisely this data and valuable information for all members.

Interview with Prof. Jack C. Ng, PhD, Diplomate of the American Board of Toxicology, University of Queensland, Brisbane, Australia
Inorganic and organic impurities on sterile packaged dental implants can lead to a foreign body reaction with activation of osteoclasts and a loss of bone in the follow-up. However, this is not the only concern as some of the particles that were found on implants using ToF-SIMS analysis may even have toxic potential. As these particles and impurities are technically avoidable, we should follow the Precautionary Principle, which says: "When an activity raises threats of harm to human health, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically."
In other words: It´s not our job to prove, that particles shown in this video are a problem for your patients. If an implant manufacturer cannot deliver his medical devices without impurities, it is the job of the manufacturer to give proof, that these impurities cause no harm. CleanImpant provides a stage for implants, that were tested "clean" and particle-free according to the guideline and established consensus.
"The very last thing your patients need right now is a contaminated implant."
Dr. Dirk Duddeck, Implantologist and Founder of the Cleanimplant Foundation, gives answers to current questions.
Prof. Tomas Albrektsson: "We have to study about impurities on implant surfaces!"
Prof. Ann Wennerberg and Prof. Tomas Albrektsson, Members of our Scientific Advisory Board, about their motivation to support the CleanImplant project.
How clean is your implant?
It should be a matter of course that all dental implants are clean when delivered in sterile packaging. Surface pollution with organic particles or significant inorganic residues, originating from the production process are suspected to cause insufficient or missing osseointegration of dental implants. Unintended micrometer-scale particles - particually organic materials such as polyethylene - induce a foreign body reaction with multinucleated giant cells and an osteoclastogenesis that can result in a loss of bone in the early stages of osseointegration.
For more than 10 years we have carried out four consecutive studies in close cooperation with the University of Cologne (Germany) and the Charité University Medicine Berlin (Germany). SEM imaging as well as elemental analyses (EDS) of more than 250 dental implants from over 200 brands were used to establish one of the largest, most comprehensive databases in implant dentistry. Recent analysis in 2018 shows more implants with severe pollution, compared with previous reports.
How many impurities can a patient tolerate?
Alarming remnants and contaminants were found in the SEM-based quality assessment. Areal pollution and particles with iron, copper, chromium, nickel, tungsten, sulfur and large quantities of stainless-steel particles, as well as remnants of polytetrafluoroethylene and other signigficant organic contaminations give cause for concern. However, we also revealed implants with clean surfaces. Read more
One manufacturer of an implant whose analysis showed severe organic contamination and embedded bronze-particles wrote to us that they could "refute the results". They "kindly invited" us "to avoid spreading information that could put a negative image on the company´s reputation".
Another manufacturer claimed that we are "melting the titanium with the energy of the scanning electron microscope" as an explantaion for the implant pollution (ironically, he had no idea how we can reach up to 1.665° C in the SEM). Another accused us of "using different sources of light (!) in the SEM" to produce unfavorable images (ignoring the fact that an SEM needs no light at all). When confronted with poor SEM analysis results, the most disturbing answer was, : "Dentists do not pay attention (for external quality assessments) or even don´t know how to interpret the results that they see." Moreover, as expected: they claimed our "research is biased".
Well, this project is our answer to an "unhealthy state of things" and why there is a need for this global quality assessment of dental implants.
Can dentists trust in the CE label ?
In the video: Dr. Dirk U. Duddeck, Implantologist and Managing Director of the CleanImplant Foundation speaks about possible failings of the European device regulation as studies - years after the PIP scandal - revealed masses of contaminants on sterile packaged dental implants.
A globally recognized label, the CleanImplant "Trusted Quality Mark" is the expression of a high quality level in the cleanliness of dental implants. It will raise the awareness of considerable differences in quality and, even more importantly, give orientation for clean implants which not only practitioners but also patients may trust.
It took years to build up your reputation as an implantogist. Yet, it can be destroyed by one negligent choice of an implant. Stay on the safe side. Choose a proven implant that carries the Trusted Quality Mark. Ask us about the cleanliness of your implant system if it does not carry the mark. Read more
Consensus Paper on "Clean Implants"
In September 2017, objective evaluation criteria for the "Trusted Quality 2017-2018" award were summarized in a consensus paper by the CleanImplant Scientific Advisory Board. The document also contains a process description of the required methods of analysis and gives proof of the CleanImplant project´s transparency.

Feedback from Colleagues
"I am a dentist in private practice in Johannesburg , South Africa. I recently attended your lecture at the SAOO congress in Durban.
I must both thank you and compliment you on the lecture which was delivered with much humour and academic excellence, and I must commend you on your research on such a difficult and sensitive topic! Prior to your lecture I had, probably like most of my colleagues, assumed that all implants on the market were of the highest standard of cleanliness. How wrong I have been!"
Mike Holmes, South Africa
"I attended your lecture in Skopje today and I was very positively surprised by all the information you shared with us. This is a game changer in the implant business. I hope you get your work published. I think we (dentists) do not pay enough attention in the surface quality since we blindly trust the manufacturers once they gain the CE stamp."
