Clean Implant

the global quality campaign


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. Become a member, join the community and support our quest for better quality in implant dentistry. Read more



Another milestone ! 

We achieved another milestone for the CleanImplant Project! With more than 15.000 subscribers only on Facebook we reach a fair number of dental professionals. With your help the CleanImplant Community is one of the fastest growing communities in the dental world. This website registered already 20.000 sessions from dental professionals of more than 130 countries around the globe. Time to say THANK YOU! Your feedback is a great motivation for us. 

If you want to participate in our project you can now join us as a Fellow Member of the CleanImplant Community.  You will not only get independent and non-biased answers to your questions, but also a personalized certificate about the cleanliness of your chosen implant system. This and additional benefits will show your patients and referral practices that you care. Find all information here and sign in for your membership.

Thank you all for your overwhelming response and support that allows us to be a voice for better quality in implant dentistry.

IDS 2019 - Impressions of a succesful week in Cologne

With members of the CleanImplant Scientific Advisory Board, Ambassadors, partners, members of the CleanImplant Community and hundreds of concerned colleagues - who want to know more about inferior quality implants, implant pollution and the clinical impact for their patients.

Thank you all for your feedback, support and valuable contribution that made this week a special one for CleanImplant.



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

Facts matter.
CleanImplant analyzes dental implants on a regular and neutral basis in a cleanroom environment according to ISO class 5 (DIN EN ISO 14644-1) - externally audited according to international standards such as DIN EN ISO 9001:2015 and DIN EN ISO/IEC 17025. To further ensure the safety and reliability of our reports, all results are peer-reviewed by a renowned Scientific Advisory Board prior to publication.

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 ?

CE label and FDA clearance are supposed to be seen as quality marks. However, impurities on sterile packaged medical devices give cause for concern.

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.

 Consensus Paper on "Clean Implants"

The CleanImplant "Trusted Quality" Mark

A global 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. 

Consensus paper

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.

EAO Congress 2018 - Trusted Quality Award for bredent medical

 Happy smiles at the EAO in Vienna as Peter Brehm, CEO of bredent medical, Germany, received the Trusted Quality 2018-2019 Award for the blueSKY implant.




Impurities on Sterile Packaged Implants:
Is the Rise of Cheap Copy-Cat Products
a Danger for our Patients?

30 years after the first SEM research into contaminations on
dental implants by Wahl et al., we can still find major impurities
on many sterile implants today. Not only clinical1,2 but also legal
implications may occur in the future if practitioners continue to use
implants of inferior quality. The quality of a dental implant is
always the result of appropriate quality management. Results of
SEM/EDS analyses in 2017 give cause for concern.

This project is open to manufacturers and suppliers of dental implants as well as companies related to the implant market who share the aims of the CleanImplant quality campaign. In fact, we do need the support of all stakeholders in our quest for quality. Every manufacturer of dental implants is therefore invited to apply for the CleanImplant "Trusted Quality Mark". 

Please contact us to find out how you can support the CleanImplant mission. 

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."

Gorazd Danilovski, Slovenia
