The CleanImplant Foundation reports about various studies (2018-2020), where the Medical Materials Research Institute (MMRI) in Berlin has found 30% of more than 300 dental implants (about 80 producers) contaminated with particles, hazardous to human health and not compliant to requirements in clean production. The analysis is performed with an electron microscope and requires the life long expertise both in data interpretation and understanding the medical implications to the human body of a specialist like Dr. Dirk Duddeck (MMRI).
