New implant coating could ‘eradicate bacteria’on 22nd May 2018
A ground-breaking new implant coating that could potentially prevent peri-implantitis has been developed in the UK.
The breakthrough is the result of a collaboration between The University of the West of England (in Bristol) and implant company Osteocare. The two organisations believe the new coating could promote osseointegration while also eradicating the oral bacteria that can lead to peri-implantitis.
The coating is based on an adhesive substance used by the edible mussel (Mytilus edulis), which has the remarkable ability to remain firmly fastened to a variety of wet surfaces.
The adhesives used by these mussels are specialised proteins that contain a high concentration of a substance known as dihydroxyphenylalanine, or Dopa. Interestingly, claim the researchers, Dopa and a related substance known as dopamine will polymerise to polydopamine (PDA) and form thin, robustly bound films at many different surfaces – even Teflon.
The PDA films in turn are rich in reactive groups, which the research team exploited in developing its novel dental implant coating.
The UK implant company Osteocare is heavily involved in research & development and cites one of its goals as continually striving to find solutions that benefit the dentist and patient alike.
