1.5 hours CPD is offered to all delegates who have booked and viewed the webinar. Bookings must have been made through the BSP website. Non-members will need their booking reference number to obtain CPD. Evaluation form and CPD certificates will be available after the event on the website.  



Dental implants replace missing teeth in at least 100 million people, yet over one million implants fail every year due to peri-implantitis, a bacterially induced inflammatory disease. Our ability to treat peri-implantitis is hampered by a paucity of information on host-microbiome interactions that underlie the disease. By characterising molecular events at the mucosal-microbial interface in the peri-implant crevice, we discovered an active peri-implant microbiome surrounding healthy implants. Microbial genes regulate human genes encoding cell development, metabolism, morphogenesis, adhesion, gap junctions, cell-cell signalling and immuno-inflammatory pathways, suggesting a role for commensals in protecting epithelial integrity. In disease, we discovered that microbial dysbiosis in the peri-implant sulcus promotes abandonment of host-bacterial transactions that dictate health and instead drives a move towards chronic programming of a non-healing wound.


  • Understand host-microbiome interactions.

  • Identify peri-implantitis as a source of implant failures.

  • Understand the role of commensals in protecting epithelial integrity.
